When --enable-shared-glapi is specified, libGL will share libglapi with
OpenGL ES instead of defining its own copy of glapi. This makes sure an
app will get only one copy of glapi in its address space.
The new option is disabled by default. When enabled, libGL and libglapi
must be built from the same source tree and distributed together. This
requirement comes from the fact that the dispatch offsets used by these
libraries are re-assigned whenever GLAPI XMLs are changed.
For GLX, indirect rendering for has_different_protocol() functions is
tricky. A has_different_protocol() function is assigned only one
dispatch offset, yet each entry point needs a different protocol opcode.
It cannot be supported by the shared glapi. The fix to this is to make
glXGetProcAddress handle such functions specially before calling
_glapi_get_proc_address.
Note that these files are automatically generated/re-generated
src/glx/indirect.c
src/glx/indirect.h
src/mapi/glapi/glapi_mapi_tmp.h
Move _glapi_* symbols from libGLESv1_CM.so and libGLESv2.so to
libglapi.so. This makes sure an app will get only one copy of glapi in
its address space.
Note that with this change, libGLES* and libglapi must be built from the
same source tree and distributed together. This requirement comes from
the fact that the dispatch offsets used by these libraries are
re-assigned whenever GLAPI XMLs are changed.
With core mesa doing runtime API checks, GLES overlay is no longer
needed. Make --enable-gles-overlay equivalent to --enable-gles[12].
There may still be places where compile-time checks are done. They
could be fixed case by case.
If you want to enable noop set GALLIUM_NOOP=1 as an env variable.
You need first to enable noop wrapping for your driver see change
to src/gallium/targets/dri-r600/ in this commit as an example.

st/egl should be enabled with --enable-openvg even the driver is xlib or
osmesa. Also, GLX_DIRECT_RENDERING should not be defined because libdrm
is not checked.
This driver is a fake swdri driver that perform no operations
beside allocation gallium structure and buffer for upper layer
usage.
It's purpose is to help profiling core mesa/gallium without
having pipe driver overhead hidding hot spot of core code.
scons file are likely inadequate i am unfamiliar with this
build system.
To use it simply rename is to swrast_dri.so and properly set
LIBGL_DRIVERS_PATH env variable.

Make autoconf decide the client APIs enabled first. Then when OpenGL
and OpenGL ES are disabled, there is no need to build src/mesa/; when
OpenGL is disabled, no $mesa_driver should be built. Finally, add
--enable-openvg to enable OpenVG.
With these changes, an OpenVG only build can be configured with
$ ./configure --disable-opengl --enable-openvg
src/mesa, src/glsl, and src/glx will be skipped, which saves a great
deal of compilation time.
And an OpenGL ES only build can be configured with
$ ./configure --disable-opengl --enable-gles-overlay
First, it changes autoconf to use a "python2" binary when available,
rather than plain "python" (which is ambiguous). Secondly, it changes
the Makefiles to use $(PYTHON) $(PYTHON_FLAGS) rather than calling
python directly.

Currently makedepend is used by the Mesa Makefile-based build system,
but not required.
Unfortunately, not having it makes dependency resolution non-existent,
which is a source of subtle bugs, and is a rarely tested
configuration, since all Mesa developers likely have it installed.
Furthermore some idioms require dependency resolution to work at all,
such as making headers depend on generated files.
Code in glx/glxcmds.c which uses the XF86VIDMODE extension is already guarded. Also use
that guard to control inclusion of the xf86vmode.h header, and only enable that guard if the
XF86VIDMODE extension is found by pkgconfig.
This changes the behaviour on platforms which XF86VIDMODE exists, in that XF86VIDMODE used to
be mandatory, but is now optional.
Presumably other build systems are already arranging for -DXF86VIDMODE to be supplied to the
complier when glxcmds.c is compiled, so are not affected by this change

Teach mklib/minstall more about cygwin so libraries are properly installed
Have mklib install the .dll into the lib/ staging directory as well
Have minstall install the .dll into PREFIX/bin at the same time as
installing the .dll.a link library into PREFIX/lib
mklib uses a '-' rather than a '.' as the separator before the version
number in library names on cygwin. Change the install globs so they match
library names like that.
