*** WARNING: THIS COMMIT CHANGES THE BUILD ***
Do not recurse into the backend directories to build private, internal
libraries.
We only recurse from clutter/ into the cogl sub-directory; from there,
we don't recurse any further. All the backend-specific code in Cogl and
Clutter is compiled conditionally depending on the macros defined by the
configure script.
We still recurse from the top-level directory into doc, clutter and
tests, because gtk-doc and tests do not deal nicely with non-recursive
layouts.
This change makes Clutter compile slightly faster, and cleans up the
build system, especially when dealing with introspection data.
Ideally, we also want to make Cogl part of the top-level build, so that
we can finally drop the sed trick to change the shared library from the
GIR before compiling it.
Currently disabled:
‣ OSX backend
‣ Fruity backend
Currently enabled but untested:
‣ EGL backend
‣ Windows backend
If no checkoutdir is specified then jhbuild seems to use the name of
the module which in this case would be 'gtk+'. This ends up
overwriting the checkout of the master branch of gtk+ and causes all
kinds of build problems. This patch adds a checkoutdir attribute to
the gtk2 module to force it to checkout into the gtk2 directory.
• Use addprefix instead of manually concatenating $(srcdir)
• Use AM_V_GEN instead of QUIET_GEN, to avoid inter-dependencies
• Do basic checks on GLIB_MKENUMS and GLIB_GENMARSHAL being defined
• Do checks on the required variables being defined
What happens now if you rename an enum inside a header:
• glib-mkenums generates the header file
• a comparison is made with the previous version of the heade is made
and no difference is found as you don't remove or create enums
• the compilation of the generated mkenums c file fails because it has
not been regenerated with the new, renamed, enum.
That's why the generated clutter-enum-types.c needs to depend on the
headers too.
Of course such scenario should not happen in stable releases as enums
are part of the API, but renaming enums happens in the development cycle
and create compilation errors (very annoying when doing git bissects for
instance).
The tests/accessibility, tests/micro-bench and the examples directory
in the coobook create a lot of non-installed binaries. Since we know who
they are, and we ignore them, we can auto-generate the ignore files as
well.
The rest of Clutter is covered by the main ignore file.
The AS_ALL_LINGUAS m4 macro allows configure-time generation of the
ALL_LINGUAS variable from the translations inside po/ instead of using
the LINGUAS file.
The script now writes out a separate script that can be used to set up
the build environment to $ROOT_DIR/share/env.sh. This can be sourced
in a shell to set up the build environment or it can be given a
command to directly execute in the environment. This makes it easier
to build Clutter from your own source rather than checking it out from
git directly.
This updates to the latest binaries from Tor Lillqvist. zlib and iconv
are now taken from the Tor deps instead of the gnuwin32 project. SDL
is no longer downloaded because the SDL backend has been removed from
Clutter. The GL headers are downloaded from the Mesa cgit rather than
downloading the whole Mesa package. glext.h is taken directly from
khronos.org.
