Sudo Installation instructions
==============================
Sudo uses a `configure' script to probe the capabilities and type
of the system in question. In this release, `configure' takes many
more options than it did before. Please read this document fully
before configuring and building sudo. You may also wish to read the
file INSTALL.configure which explains more about the `configure' script.
Simple sudo installation
========================
For most systems and configurations it is possible simply to:
0) If you are upgrading from a previous version of sudo
please read the info in the UPGRADE file before proceeding.
1) Read the `OS dependent notes' section for any particular
"gotchas" relating to your operating system.
2) `cd' to the source or build directory and type `./configure'
to generate a Makefile and config.h file suitable for
building sudo. Before you actually run configure you
should read the `Available configure options' section
to see if there are any special options you may want
or need.
3) Edit the configure-generated Makefile if you wish to
change any of the default paths (alternatively, you could
have changed the paths via options to `configure'.
5) Type `make' to compile sudo. If you are building sudo
in a separate build tree (apart from the sudo source) GNU
make will probably be required. If `configure' did its job
properly (and you have a supported configuration) there won't
be any problems. If this doesn't work, take a look at the
TROUBLESHOOTING file for tips on what might have gone wrong.
Please mail us if you have a fix or if you are unable to
come up with a fix (address at EOF).
6) Type `make install' (as root) to install sudo, visudo, the
man pages, and a skeleton sudoers file. Note that the install
will not overwrite an existing sudoers file. You can also
install various pieces the package via the install-binaries,
install-doc, and install-sudoers make targets.
7) Edit the sudoers file with `visudo' as necessary for your
site. You will probably want to refer the sample.sudoers
file and sudoers man page included with the sudo package.
8) If you want to use syslogd(8) to do the logging, you'll need
to update your /etc/syslog.conf file. See the sample.syslog.conf
file included in the distribution for an example.
Available configure options
===========================
This section describes flags accepted by the sudo's `configure' script.
Defaults are listed in brackets after the description.
Configuration:
--cache-file=FILE
Cache test results in FILE
--config-cache, -C
Alias for `--cache-file=config.cache'
--help, -h
Print the usage/help info
--no-create, -n
Do not create output files
--quiet, --silent, -q
Do not print `checking...' messages
Directory and file names:
--prefix=PREFIX
Install architecture-independent files in PREFIX This really only
applies to man pages. [/usr/local]
--exec-prefix=EPREFIX
Install architecture-dependent files in EPREFIX This includes the
sudo and visudo executables. [same as prefix]
--bindir=DIR
Install `sudo' in DIR [EPREFIX/bin]
--sbindir=DIR
Install `visudo' in DIR [EPREFIX/sbin]
--sysconfdir=DIR
Install `sudoers' file in DIR [/etc]
--mandir=DIR
Install man pages in DIR [PREFIX/man]
--srcdir=DIR
Find the sources in DIR [configure dir or ..]
Special features/options:
--with-CC=PATH
Specifies path to C compiler you wish to use.
--with-incpath=DIR
Adds the specified directory (or directories) to CPPFLAGS
so configure and the compiler will look there for include
files. Multiple directories may be specified as long as
they are space separated.
Eg: --with-incpath="/usr/local/include /opt/include"
--with-libpath=DIR
Adds the specified directory (or directories) to LDFLAGS
so configure and the compiler will look there for libraries.
Multiple directories may be specified as with --with-incpath.
--with-rpath
Tells configure to use -Rpath in addition to -Lpath when
passing library paths to the loader. This option is on
by default for Solaris and SVR4.
--with-blibpath[=PATH]
Tells configure to construct a -blibpath argument to the
loader. If a PATH is specified, it will be used as the
base. Otherwise, "/usr/lib:/lib:/usr/local/lib" will be
used for gcc and "/usr/lib:/lib" for non-gcc. Additional
library paths will be appended as needed by configure.
This option is only valid for AIX where it is on by default.
--with-libraries=LIBRARY
Adds the specified library (or libaries) to SUDO_LIBS and
and VISUDO_LIBS so sudo will link against them. If the
library doesn't start with `-l' or end in `.a' or `.o' a
`-l' will be prepended to it. Multiple libraries may be
specified as long as they are space separated.
--with-plugindir=PATH
Set the directory that sudo looks in to find the policy and I/O
logging plugins. Defaults to the libexec dir used by configure.
--with-efence
Link with the "electric fence" debugging malloc.
--with-bsm-audit
Enable support for sudo BSM audit logs on systems that support
it. Currently only supported under FreeBSD and Mac OS X.
--with-csops
Add CSOps standard options. You probably aren't interested in this.
--with-devel
Configure development options. This will enable compiler warnings
and set the Makefile to be able to regenerate the sudoers parser
as well as the manual pages.
--with-linux-audit
Enable audit support for Linux systems. Audits attempts
to run a command as well as SELinux role changes.
--with-skey[=DIR]
Enable S/Key OTP (One Time Password) support. If specified,
DIR should contain include and lib directories with skey.h
and libskey.a respectively.
--with-opie[=DIR]
Enable NRL OPIE OTP (One Time Password) support. If specified,
DIR should contain include and lib directories with opie.h
and libopie.a respectively.
--with-SecurID[=DIR]
Enable SecurID support. If specified, DIR is directory containing
sdiclient.a, sdi_athd.h, sdconf.h, and sdacmvls.h.
--with-fwtk[=DIR]
Enable TIS Firewall Toolkit (FWTK) 'authsrv' support. If specified,
DIR is the base directory containing the compiled FWTK package
(or at least the library and header files).
--with-kerb4[=DIR]
Enable Kerberos IV support. If specified, DIR is the base
directory containing the Kerberos IV include and lib dirs.
This uses Kerberos passphrases for authentication but does
not use the Kerberos cookie scheme.
--with-kerb5[=DIR]
Enable Kerberos V support. If specified, DIR is the base
directory containing the Kerberos V include and lib dirs.
This This uses Kerberos passphrases for authentication but
does not use the Kerberos cookie scheme. Will not work for
Kerberos V older than version 1.1.
--with-ldap[=DIR]
Enable LDAP support. If specified, DIR is the base directory
containing the LDAP include and lib directories. Please see
README.LDAP for more information.
--with-ldap-conf-file=PATH
Path to LDAP configuration file. If specified, sudo reads
this file instead of /etc/ldap.conf to locate the LDAP server.
--with-ldap-secret-file=PATH
Path to LDAP secret password file. If specified, sudo uses
this file instead of /etc/ldap.secret to read the secret password
when rootbinddn is specified in the ldap config file.
--with-nsswitch[=PATH]
Path to nsswitch.conf or "no" to disable nsswitch support.
If specified, sudo uses this file instead of /etc/nsswitch.conf.
If nsswitch is disabled but LDAP is enabled, sudo will check
LDAP first, then the sudoers file.
--with-netsvc[=PATH]
Path to netsvc.conf or "no" to disable netsvc.conf support.
If specified, sudo uses this file instead of /etc/netsvc.conf
on AIX systems.
--with-aixauth
Enable support for the AIX 4.x general authentication function.
This will use the authentication scheme specified for the user
on the machine. It is on by default for AIX systems that
support it.
--with-pam
Enable PAM support. This is on by default for Darwin, FreeBSD,
Linux, Solaris and HP-UX (version 11 and higher).
NOTE: on RedHat Linux and Fedora you *must* have an /etc/pam.d/sudo
file install. You may either use the sample.pam file included with
sudo or use /etc/pam.d/su as a reference. The sample.pam file
included with sudo may or may not work with other Linux distributions.
On Solaris and HP-UX 11 systems you should check (and understand)
the contents of /etc/pam.conf. Do a "man pam.conf" for more
information and consider using the "debug" option, if available,
with your PAM libraries in /etc/pam.conf to obtain syslog output
for debugging purposes.
--with-pam-login
Enable a specific PAM session when sudo is given the -i option.
This changes the PAM service name when sudo is run with the -i
option from "sudo" to "sudo-i", allowing for a separate pam
configuration for sudo's initial login mode.
--with-AFS
Enable AFS support with Kerberos authentication. Should work under
AFS 3.3. If your AFS doesn't have -laudit you should be able to
link without it.
--with-DCE
Enable DCE support for systems without PAM. Known to work on
HP-UX 9.X, 10.X, and 11.0; other systems may require source
code and/or `configure' changes. On systems with PAM support
(such as HP-UX 11.0 and higher, Solaris, FreeBSD and Linux), the
DCE PAM module (usually libpam_dce) should be used instead.
--with-logincap
This adds support for login classes specified in /etc/login.conf.
It is enabled by default on BSD/OS, Darwin, FreeBSD, OpenBSD and
NetBSD (where available). By default, a login class is not applied
unless the 'use_loginclass' option is defined in sudoers or the user
specifies a class on the command line.
--with-bsdauth
Enable support for BSD authentication. This is the default
for BSD/OS and OpenBSD systems that support it.
It is not possible to mix BSD authentication with other
authentication methods (and there really should be no need
to do so). Note that only the newer BSD authentication API
is supported. If you don't have /usr/include/bsd_auth.h
then you cannot use this.
--with-project
Enable support for Solaris project resource limits.
This option is only available on Solaris 9 and above.
--with-noexec[=PATH]
Enable support for the "noexec" functionality which prevents
a dynamically-linked program being run by sudo from executing
another program (think shell escapes). Please see the
"PREVENTING SHELL ESCAPES" section in the sudoers man page
for details. If specified, PATH should be a fully qualified
path name, e.g. /usr/local/libexec/sudo_noexec.so. If PATH
is "no", noexec support will not be compiled in. The default
is to compile noexec support if libtool supports building
shared objects on your OS.
--disable-pam-session
Disable sudo's PAM session support. This may be needed on
older PAM implementations or on operating systems where
opening a PAM session changes the utmp or wtmp files. If
PAM session support is disabled, resource limits may not
be updatedin for command being run.
--disable-root-mailer
By default sudo will run the mailer as root when tattling
on a user so as to prevent that user from killing the mailer.
With this option, sudo will run the mailer as the invoking
user which some people consider to be safer.
--disable-setreuid
Disable use of the setreuid() function for operating systems
where it is broken. Mac OS X has setreuid() but it doesn't
really work.
--disable-setresuid
Disable use of the setresuid() function for operating systems
where it is broken (none currently known).
--disable-sia
Disable SIA support. This is the "Security Integration
Architecture" on Digital UNIX. If you disable SIA sudo will
use its own authentication routines.
--disable-shadow
Disable shadow password support. Normally, sudo will compile
in shadow password support and use a shadow password if it
exists.
--with-sudoers-mode=MODE
File mode for the sudoers file (octal). Note that if you
wish to NFS-mount the sudoers file this must be group
readable. Also note that this is actually set in the
Makefile. The default mode is 0440.
--with-sudoers-uid=UID
User id that "owns" the sudoers file. Note that this is
the numeric id, *not* the symbolic name. Also note that
this is actually set in the Makefile. The default is 0.
--with-sudoers-gid=GID
Group id that "owns" the sudoers file. Note that this is
the numeric id, *not* the symbolic name. Also note that
this is actually set in the Makefile. The default is 0.
--without-interfaces
This option keeps sudo from trying to glean the ip address
from each attached ethernet interface. It is only useful
on a machine where sudo's interface reading support does
not work, which may be the case on some SysV-based OS's
using STREAMS.
--without-passwd
This option excludes authentication via the passwd (or
shadow) file. It should only be used when another, alternative,
authentication scheme is in use.
--with-otp-only
This option is now just an alias for --without-passwd.
--with-stow
Properly handle GNU stow packaging. The sudoers file will
physically live in ${prefix}/etc and /etc/sudoers will be
a symbolic link.
--with-selinux
Enable support for role based access control (RBAC) on
systems that support SELinux.
The following options are also configurable at runtime:
--with-long-otp-prompt
When validating with a One Time Password scheme (S/Key or
OPIE), a two-line prompt is used to make it easier to cut
and paste the challenge to a local window. It's not as
pretty as the default but some people find it more convenient.
--with-logging=TYPE
How you want to do your logging. You may choose "syslog",
"file", or "both". Setting this to "syslog" is nice because
you can keep all of your sudo logs in one place (see the
sample.syslog.conf file). The default is "syslog".
--with-logfac=FACILITY
Determines which syslog facility to log to. This requires
a 4.3BSD or later version of syslog. You can still set
this for ancient syslogs but it will have no effect. The
following facilities are supported: authpriv (if your OS
supports it), auth, daemon, user, local0, local1, local2,
local3, local4, local5, local6, and local7.
--with-goodpri=PRIORITY
Determines which syslog priority to log successfully
authenticated commands. The following priorities are
supported: alert, crit, debug, emerg, err, info, notice,
and warning.
--with-badpri=PRIORITY
Determines which syslog priority to log unauthenticated
commands and errors. The following priorities are supported:
alert, crit, debug, emerg, err, info, notice, and warning.
--with-logpath=PATH
Override the default location of the sudo log file and use
"path" instead. By default will use /var/log/sudo.log if
there is a /var/log dir, falling back to /var/adm/sudo.log
or /usr/adm/sudo.log if not.
--with-loglen=NUMBER
Number of characters per line for the file log. This is only used if
you are to "file" or "both". This value is used to decide when to wrap
lines for nicer log files. The default is 80. Setting this to 0
will disable the wrapping.
--with-ignore-dot
If set, sudo will ignore '.' or '' (current dir) in $PATH.
The $PATH itself is not modified.
--with-mailto=USER|MAIL_ALIAS
User (or mail alias) that mail from sudo is sent to.
This should go to a sysadmin at your site. The default is "root".
--with-mailsubject="SUBJECT OF MAIL"
Subject of the mail sent to the "mailto" user. The token "%h"
will expand to the hostname of the machine.
Default is "*** SECURITY information for %h ***".
--without-mail-if-no-user
Normally, sudo will mail to the "alertmail" user if the user invoking
sudo is not in the sudoers file. This option disables that behavior.
--with-mail-if-no-host
Send mail to the "alermail" user if the user exists in the sudoers
file, but is not allowed to run commands on the current host.
--with-mail-if-noperms
Send mail to the "alermail" user if the user is allowed to use sudo but
the command they are trying is not listed in their sudoers file entry.
--with-passprompt="PASSWORD PROMPT"
Default prompt to use when asking for a password; can be overridden
via the -p option and the SUDO_PROMPT environment variable. Supports
the "%H", "%h", "%U" and "%u" escapes as documented in the sudo
manual page. The default value is "Password:".
--with-badpass-message="BAD PASSWORD MESSAGE"
Message that is displayed if a user enters an incorrect password.
The default is "Sorry, try again." unless insults are turned on.
--with-fqdn
Define this if you want to put fully qualified hostnames in the sudoers
file. Ie: instead of myhost you would use myhost.mydomain.edu. You may
still use the short form if you wish (and even mix the two). Beware
that turning FQDN on requires sudo to make DNS lookups which may make
sudo unusable if your DNS is totally hosed. Also note that you must
use the host's official name as DNS knows it. That is, you may not use
a host alias (CNAME entry) due to performance issues and the fact that
there is no way to get all aliases from DNS.
--with-timedir=PATH
Override the default location of the sudo timestamp directory and
use "path" instead.
--with-sendmail=PATH
Override configure's guess as to the location of sendmail.
--without-sendmail
Do not use sendmail to mail messages to the "mailto" user.
Use only if don't run sendmail or the equivalent.
--with-umask=MASK
Umask to use when running the root command. The default is 0022.
--without-umask
Preserves the umask of the user invoking sudo.
--with-umask-override
Use the umask specified in sudoers even if it is less restrictive
than the user's. The default is to use the intersection of the
user's umask and the umask specified in sudoers.
--with-runas-default=USER
The default user to run commands as if the -u flag is not specified
on the command line. This defaults to "root".
--with-exempt=GROUP
Users in the specified group don't need to enter a password when
running sudo. This may be useful for sites that don't want their
"core" sysadmins to have to enter a password but where Jr. sysadmins
need to. You should probably use NOPASSWD in sudoers instead.
--with-passwd-tries=NUMBER
Number of tries a user gets to enter his/her password before sudo logs
the failure and exits. The default is 3.
--with-timeout=NUMBER
Number of minutes that can elapse before sudo will ask for a passwd
again. The default is 5, set this to 0 to always prompt for a password.
--with-password-timeout=NUMBER
Number of minutes before the sudo password prompt times out.
The default is 5, set this to 0 for no password timeout.
--without-tty-tickets
By default, sudo uses a different ticket file for each user/tty combo.
With this option disabled, a single ticket will be used for all
of a user's login sessions.
--with-insults
Define this if you want to be insulted for typing an incorrect password
just like the original sudo(8). This is off by default.
--with-insults=disabled
Include support for insults but disable them unless explicitly
enabled in sudoers.
--with-all-insults
Include all the insult sets listed below. You must either specify
--with-insults or enable insults in the sudoers file for this to
have any effect.
--with-classic-insults
Uses insults from sudo "classic." If you just specify --with-insults
you will get the classic and CSOps insults. This is on by default if
--with-insults is given.
--with-csops-insults
Insults the user with an extra set of insults (some quotes, some
original) from a sysadmin group at CU (CSOps). You must specify
--with-insults as well for this to have any effect. This is on by
default if --with-insults is given.
--with-hal-insults
Uses 2001-like insults when an incorrect password is entered.
You must either specify --with-insults or enable insults in the
sudoers file for this to have any effect.
--with-goons-insults
Insults the user with lines from the "Goon Show" when an incorrect
password is entered. You must either specify --with-insults or
enable insults in the sudoers file for this to have any effect.
--with-pc-insults
Replace politically incorrect insults with less objectionable ones.
--with-secure-path[=PATH]
Path used for every command run from sudo(8). If you don't trust the
people running sudo to have a sane PATH environment variable you may
want to use this. Another use is if you want to have the "root path"
be separate from the "user path." You will need to customize the path
for your site. NOTE: this is not applied to users in the group
specified by --with-exemptgroup. If you do not specify a path,
"/bin:/usr/ucb:/usr/bin:/usr/sbin:/sbin:/usr/etc:/etc" is used.
--without-lecture
Don't print the lecture the first time a user runs sudo.
--with-editor=PATH
Specify the default editor path for use by visudo. This may be a
single path name or a colon-separated list of editors. In the latter
case, visudo will choose the editor that matches the user's VISUAL
or EDITOR environment variables or the first editor in the list that
exists. The default is the path to vi on your system.
--with-env-editor
Makes visudo consult the VISUAL and EDITOR environment variables before
falling back on the default editor list (as specified by --with-editor).
Note that this may create a security hole as it allows the user to
run any arbitrary command as root without logging. A safer alternative
is to use a colon-separated list of editors with the --with-editor
option. visudo will then only use the VISUAL or EDITOR variables
if they match a value specified via --with-editor.
--with-askpass=PATH
Set PATH as the "askpass" program to use when no tty is
available. Typically, this is a graphical password prompter,
similar to the one used by ssh. The program must take a
prompt as an argument and print the received password to
the standard output.
--with-iologdir[=DIR]
By default, sudo stores I/O log files in either /var/log/sudo-io,
/var/adm/sudo-io, or /usr/log/sudo-io. If this option is
specified, I/O logs will be stored in the indicated directory
instead.
--disable-authentication
By default, sudo requires the user to authenticate via a
password or similar means. This options causes sudo to
*not* require authentication. It is possible to turn
authentication back on in sudoers via the PASSWD attribute.
--disable-root-sudo
Don't let root run sudo. This can be used to prevent people from
"chaining" sudo commands to get a root shell by doing something
like "sudo sudo /bin/sh".
--enable-gss-krb5-ccache-name
Use the gss_krb5_ccache_name() function to set the Kerberos
V credential cache file name. By default, sudo will use
the KRB5CCNAME environment variable to set this. While
gss_krb5_ccache_name() provides a better API to do this it
is not supported by all Kerberos V and SASL combinations.
--enable-log-host
Log the hostname in the log file.
--enable-noargs-shell
If sudo is invoked with no arguments it acts as if the "-s" flag had
been given. That is, it runs a shell as root (the shell is determined
by the SHELL environment variable, falling back on the shell listed
in the invoking user's /etc/passwd entry).
--enable-shell-sets-home
If sudo is invoked with the "-s" flag the HOME environment variable
will be set to the home directory of the target user (which is root
unless the "-u" option is used). This option effectively makes the
"-s" flag imply "-H".
--disable-path-info
Normally, sudo will tell the user when a command could not be found
in their $PATH. Some sites may wish to disable this as it could
be used to gather information on the location of executables that
the normal user does not have access to. The disadvantage is that
if the executable is simply not in the user's path, sudo will tell
the user that they are not allowed to run it, which can be confusing.
--enable-zlib[=location]
Enable the use of the zlib compress library when storing
I/O log files. If specified, location is the base directory
containing the zlib include and lib directories. The special
values "system" and "builtin" can be used to indicate that
the system version of zlib should be used or that the version
of zlib shipped with sudo should be used instead.
If this option is not specified, configure will use the
system zlib if it is present.
--disable-zlib
Disable the use of the zlib compress library when storing
I/O log files.
--enable-warnings
Enable compiler warnings when building sudo with gcc.
--enable-admin-flag
Enable the creation of an Ubuntu-style admin flag file
the first time sudo is run.
--disable-env-reset
Disable environment resetting. This sets the default value
of the "env_reset" Defaults option in sudoers to false.
--enable-nls[=location]
Enable natural language support using the gettext() family
of functions. If specified, location is the base directory
containing the libintl include and lib directories. If
this option is not specified, configure will look for the
gettext() family of functions in the standard C library
first, then check for a standalone libintl (linking with
libiconv as needed).
--disable-nls
Disable natural language support. By default, sudo will
use the gettext() family of functions, if available, to
implement messages in the invoking user's native language.
Note that translations do not exist for all languages.
Shadow password and C2 support
==============================
Shadow passwords (also included with most C2 security packages) are
supported on most major platforms for which they exist. The
`configure' script will attempt to determine if your system can use
shadow passwords and include support for them if so. Shadow password
support is now compiled in by default (it doesn't hurt anything if you
don't have them configured). To disable the shadow password support,
use the --disable-shadow option to configure.
Shadow passwords are known to work on the following platforms:
SunOS 4.x
Solaris 2.x
HP-UX >= 9.x
Ultrix 4.x
Digital UNIX
IRIX >= 5.x
AIX >= 3.2.x
Linux
SCO >= 3.2.2
Pyramid DC/OSx
UnixWare
SVR4 (and variants using standard SVR4 shadow passwords)
4.4BSD based systems (including OpenBSD, NetBSD, FreeBSD, and Mac OS X)
Systems using SecureWare's C2 security.
OS dependent notes
==================
Linux:
PAM and LDAP headers are not installed by default on most Linux
systems. You will need to install the "pam-dev" package if
/usr/include/security/pam_appl.h is not present on your system.
If you wish to build with LDAP support you will also need the
openldap-devel package.
Versions of glibc 2.x previous to 2.0.7 have a broken lsearch().
You will need to either upgrade to glibc-2.0.7 or use sudo's
version of lsearch(). To use sudo's lsearch(), comment out
the "#define HAVE_LSEARCH 1" line in config.h and add lsearch.o
to the LIBOBJS line in the Makefile.
If you are using a Linux kernel older than 2.4 it is not possible
to access the sudoers file via NFS. This is due to a bug in
the Linux client-side NFS implementation that has since been
fixed. There is a workaround on the sudo ftp site, linux_nfs.patch,
if you need to NFS-mount sudoers on older Linux kernels.
Solaris 2.x:
You need to have a C compiler in order to build sudo. Since
Solaris 2.x does not come with one by default this means that
you either need to install the Sun Studio compiler suite,
available for free from www.sun.com, or have a copy of the GNU
C compiler (gcc) which is distributed on the Solaris Companion
CD. You can also get them from various places on the net,
including http://www.sunfreeware.com/
NOTE: sudo will *not* build with the sun C compiler in BSD
compatibility mode (/usr/ucb/cc). Sudo is designed to
compile with the standard C compiler (or gcc) and will
not build correctly with /usr/ucb/cc. You can use the
`--with-CC' option to point `configure' to the non-ucb
compiler if it is not the first cc in your path. Some
sites link /usr/ucb/cc to gcc; configure will not notice
this and still refuse to use /usr/ucb/cc, so make sure gcc
is also in your path if your site is setup this way.
Also: Older versions of Solaris come with a broken syslogd.
If you have having problems with sudo logging you should
make sure you have the latest syslogd patch installed.
This is a problem for Solaris 2.4 and 2.5 at least.
Mac OS X:
The pseudo-tty support in the Mac OS X kernel has bugs related
to its handling of the SIGTSTP, SIGTTIN and SIGTTOU signals.
It does not restart reads and writes when those signals are
delivered. This may cause problems for some commands when I/O
logging is enabled. The issue has been reported to Apple and
is bug id #7952709.
HP-UX:
The default C compiler shipped with HP-UX is not an ANSI compiler.
You must use either the HP ANSI C compiler or gcc to build sudo.
Binary packages of gcc are available from http://hpux.connect.org.uk/.
To prevent PAM from overriding the value of umask on HP-UX 11,
you will need to add a line like the following to /etc/pam.conf:
sudo session required libpam_hpsec.so.1 bypass_umask
Digital UNIX:
By default, sudo will use SIA (Security Integration Architecture)
to validate a user. If you want to use an alternative authentication
method that does not go through SIA, you need to use the
--disable-sia option to configure. If you use gcc to compile
you will get warnings when building interfaces.c. These are
harmless but if they really bug you, you can edit
/usr/include/net/if.h around line 123, right after the comment:
/* forward decls for C++ */
change the line:
#ifdef __cplusplus
to:
#if defined(__cplusplus) || defined(__GNUC__)
If you don't like the idea of editing the system header file
you can just make a copy in gcc's private include tree and
edit that.
AIX 3.2.x:
I've had various problems with the AIX C compiler producing
incorrect code when the -O flag was used. When optimization
is not used, the problems go away. Gcc does not appear
to have this problem.
SCO ODT:
You'll probably need libcrypt_i.a available via anonymous ftp
from sosco.sco.com. The necessary files are /SLS/lng225b.Z
and /SLS/lng225b.ltr.Z.
SunOS 4.x:
SunOS does not ship with an ANSI C compiler. You will need to
install an ANSI compiler such as gcc to build sudo.
The /bin/sh shipped with SunOS blows up while running configure.
You can work around this by installing bash or zsh. If you
have bash or zsh in your path, configure will use it instead
automatically.
ULTRIX 4.x:
ULTRIX does not ship with an ANSI C compiler. You will need to
install an ANSI compiler such as gcc to build sudo.
The /bin/sh shipped with ULTRIX blows up while running configure.
You can work around this by installing bash or zsh. If you
have bash or zsh in your path, configure will use it instead
automatically.
ULTRIX ships with the 4.2BSD syslog(3) which does not
allow things like logging different facilities to different
files, redirecting logs to a single loghost and other niceties.
You may want to just grab and install:
ftp://www.sudo.ws/pub/sudo/misc/jtkohl-syslog-complete.tar.gz
(available via anonymous ftp) which is a port if the 4.3BSD
syslog/syslogd that is backwards compatible with the Ultrix version.
I recommend it highly. If you do not do this you probably want
to run configure with --with-logging=file
