# This file is your local configuration file and is where all local user settings
|
|
# are placed. The comments in this file give some guide to the options a new user
|
|
# to the system might want to change but pretty much any configuration option can
|
|
# be set in this file. More adventurous users can look at local.conf.extended
|
|
# which contains other examples of configuration which can be placed in this file
|
|
# but new users likely won't need any of them initially.
|
|
#
|
|
# Lines starting with the '#' character are commented out and in some cases the
|
|
# default values are provided as comments to show people example syntax. Enabling
|
|
# the option is a question of removing the # character and making any change to the
|
|
# variable as required.

|
# Machine Selection
|
|
#
|
|
# You need to select a specific machine to target the build with. There are a selection
|
|
# of emulated machines available which can boot and run in the QEMU emulator:
|
|
#
|
|
#MACHINE ?= "qemuarm"
|
|
#MACHINE ?= "qemuarm64"
|
|
#MACHINE ?= "qemumips"
|
|
#MACHINE ?= "qemumips64"
|
|
#MACHINE ?= "qemuppc"
|
|
#MACHINE ?= "qemux86"
|
|
#MACHINE ?= "qemux86-64"
|
|
#
|
|
# There are also the following hardware board target machines included for
|
|
# demonstration purposes:
|
|
#
|
|
#MACHINE ?= "beaglebone-yocto"
|
|
#MACHINE ?= "genericx86"
|
|
#MACHINE ?= "genericx86-64"
|
|
#MACHINE ?= "mpc8315e-rdb"
|
|
#MACHINE ?= "edgerouter"
|
|
#
|
|
# This sets the default machine to be qemux86 if no other machine is selected:
|
|
MACHINE ??= "qemux86"
|
|
|
|
#
|
|
# Where to place downloads
|
|
#
|
|
# During a first build the system will download many different source code tarballs
|
|
# from various upstream projects. This can take a while, particularly if your network
|
|
# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
|
|
# can preserve this directory to speed up this part of subsequent builds. This directory
|
|
# is safe to share between multiple builds on the same machine too.
|
|
#
|
|
# The default is a downloads directory under TOPDIR which is the build directory.
|
|
#
|
|
#DL_DIR ?= "${TOPDIR}/downloads"
|
|
|
|
#
|
|
# Where to place shared-state files
|
|
#
|
|
# BitBake has the capability to accelerate builds based on previously built output.
|
|
# This is done using "shared state" files which can be thought of as cache objects
|
|
# and this option determines where those files are placed.
|
|
#
|
|
# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
|
|
# from these files if no changes were made to the configuration. If changes were made
|
|
# to the configuration, only shared state files where the state was still valid would
|
|
# be used (done using checksums).
|
|
#
|
|
# The default is a sstate-cache directory under TOPDIR.
|
|
#
|
|
#SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
|
|
|
|
#
|
|
# Where to place the build output
|
|
#
|
|
# This option specifies where the bulk of the building work should be done and
|
|
# where BitBake should place its temporary files and output. Keep in mind that
|
|
# this includes the extraction and compilation of many applications and the toolchain
|
|
# which can use Gigabytes of hard disk space.
|
|
#
|
|
# The default is a tmp directory under TOPDIR.
|
|
#
|
|
#TMPDIR = "${TOPDIR}/tmp"
|
|
|
|
#
|
|
# Default policy config
|
|
#
|
|
# The distribution setting controls which policy settings are used as defaults.
|
|
# The default value is fine for general Yocto project use, at least initially.
|
|
# Ultimately when creating custom policy, people will likely end up subclassing
|
|
# these defaults.
|
|
#
|
|
DISTRO ?= "poky"
|
|
# As an example of a subclass there is a "bleeding" edge policy configuration
|
|
# where many versions are set to the absolute latest code from the upstream
|
|
# source control systems. This is just mentioned here as an example, its not
|
|
# useful to most new users.

# DISTRO ?= "poky-bleeding"

|
# Package Management configuration
|
|
#
|
|
# This variable lists which packaging formats to enable. Multiple package backends
|
|
# can be enabled at once and the first item listed in the variable will be used
|
|
# to generate the root filesystems.
|
|
# Options are:
|
|
# - 'package_deb' for debian style deb files
|
|
# - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
|
|
# - 'package_rpm' for rpm style packages
|
|
# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
|
|
# We default to rpm:
|
|
PACKAGE_CLASSES ?= "package_rpm"

#
|
|
# SDK target architecture
|
|
#
|
|
# This variable specifies the architecture to build SDK items for and means
|
|
# you can build the SDK packages for architectures other than the machine you are
|
|
# running the build on (i.e. building i686 packages on an x86_64 host).
|
|
# Supported values are i686 and x86_64
|

#SDKMACHINE ?= "i686"

|
|
# Extra image configuration defaults
|
|
#
|
|
# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
|
|
# images. Some of these options are added to certain image types automatically. The
|
|
# variable can contain the following options:
|
|
# "dbg-pkgs" - add -dbg packages for all installed packages
|
|
# (adds symbol information for debugging/profiling)
|
|
# "dev-pkgs" - add -dev packages for all installed packages
|
|
# (useful if you want to develop against libs in the image)
|
|
# "ptest-pkgs" - add -ptest packages for all ptest-enabled packages
|
|
# (useful if you want to run the package test suites)
|
|
# "tools-sdk" - add development tools (gcc, make, pkgconfig etc.)
|
|
# "tools-debug" - add debugging tools (gdb, strace)
|
|
# "eclipse-debug" - add Eclipse remote debugging support
|
|
# "tools-profile" - add profiling tools (oprofile, lttng, valgrind)
|
|
# "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
|
|
# "debug-tweaks" - make an image suitable for development
|
|
# e.g. ssh root access has a blank password
|
|
# There are other application targets that can be used here too, see
|
|
# meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.

# The following is a list of additional classes to use when building images which

# enable extra features. Some available options which can be included in this variable

|
# are:
|
|
# - 'buildstats' collect build statistics
|
|
# - 'image-mklibs' to reduce shared library files size for an image
|
|
# - 'image-prelink' in order to prelink the filesystem image
|
|
# NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
|
|
# NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended

|
|
# after any root filesystems are created and run tests against those images. To
|
|
# enable this uncomment this line. See classes/testimage(-auto).bbclass for
|

|
# Interactive shell configuration
|
|
#
|
|
# Under certain circumstances the system may need input from you and to do this it
|
|
# can launch an interactive shell. It needs to do this since the build is
|
|
# multithreaded and needs to be able to handle the case where more than one parallel
|
|
# process may require the user's attention. The default is iterate over the available
|
|
# terminal types to find one that works.
|
|
#
|
|
# Examples of the occasions this may happen are when resolving patches which cannot
|
|
# be applied, to use the devshell or the kernel menuconfig
|
|
#
|
|
# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
|
|
# Note: currently, Konsole support only works for KDE 3.x due to the way
|
|
# newer Konsole versions behave

# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
|
|
# shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
|
|
# of the build. The reason for this is that running completely out of space can corrupt
|
|
# files and damages the build in ways which may not be easily recoverable.
|
|
# It's necesary to monitor /tmp, if there is no space left the build will fail
|
|
# with very exotic errors.

#
|

# This can be a filesystem directory, or a remote url such as http or ftp. These
|

|
|
# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
|
|
# cache locations to check for the shared objects.
|
|
# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
