* glapi: add glapi_gen.mk to help header generationChia-I Wu2011-08-131-5/+4
| | | | | | | | | | | glapi_gen.mk is supposed to be included by glapi users to simplify header generation. This commit also makes es1api, es2api, and shared-glapi use it. Reviewed-by: Brian Paul <[email protected]> [olv: updated after reviewing to prefix all variables in glapi_gen.mk by glapi_gen]
* mapi: Workaround a bug in makedepend.Chia-I Wu2011-01-291-1/+6
| | | | | | | | | | | | | makedepend would crash when a source includes a header indirectly, such as #define HEADER "some-header.h" #include HEADER Do not define HEADER (makedepend would detects this as an incomplete include) and add the dependency manually in the Makefile. This should hopefully fix bug #33374.
* glapi: Fix OpenGL and OpenGL ES interop.Chia-I Wu2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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
* glapi: Fix OpenGL ES 1.1 and 2.0 interop.Chia-I Wu2011-01-201-0/+61
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.
