Intial Re-layout of the Cogl source code and introduction of a Cogl Winsys As part of an incremental process to have Cogl be a standalone project we want to re-consider how we organise the Cogl source code. Currently this is the structure I'm aiming for: cogl/ cogl/ <put common source here> winsys/ cogl-glx.c cogl-wgl.c driver/ gl/ gles/ os/ ? utils/ cogl-fixed cogl-matrix-stack? cogl-journal? cogl-primitives? pango/ The new winsys component is a starting point for migrating window system code (i.e. x11,glx,wgl,osx,egl etc) from Clutter to Cogl. The utils/ and pango/ directories aren't added by this commit, but they are noted because I plan to add them soon. Overview of the planned structure: * The winsys/ API is the API that binds OpenGL to a specific window system, be that X11 or win32 etc. Example are glx, wgl and egl. Much of the logic under clutter/{glx,osx,win32 etc} should migrate here. * Note there is also the idea of a winsys-base that may represent a window system for which there are multiple winsys APIs. An example of this is x11, since glx and egl may both be used with x11. (currently only Clutter has the idea of a winsys-base) * The driver/ represents a specific varient of OpenGL. Currently we have "gl" representing OpenGL 1.4-2.1 (mostly fixed function) and "gles" representing GLES 1.1 (fixed funciton) and 2.0 (fully shader based) * Everything under cogl/ should fundamentally be supporting access to the GPU. Essentially Cogl's most basic requirement is to provide a nice GPU Graphics API and drawing a line between this and the utility functionality we add to support Clutter should help keep this lean and maintainable. * Code under utils/ as suggested builds on cogl/ adding more convenient APIs or mechanism to optimize special cases. Broadly speaking you can compare cogl/ to OpenGL and utils/ to GLU. * clutter/pango will be moved to clutter/cogl/pango How some of the internal configure.ac/pkg-config terminology has changed: backendextra -> CLUTTER_WINSYS_BASE # e.g. "x11" backendextralib -> CLUTTER_WINSYS_BASE_LIB # e.g. "x11/libclutter-x11.la" clutterbackend -> {CLUTTER,COGL}_WINSYS # e.g. "glx" CLUTTER_FLAVOUR -> {CLUTTER,COGL}_WINSYS clutterbackendlib -> CLUTTER_WINSYS_LIB CLUTTER_COGL -> COGL_DRIVER # e.g. "gl" Note: The CLUTTER_FLAVOUR and CLUTTER_COGL defines are kept for apps As the first thing to take advantage of the new winsys component in Cogl; cogl_get_proc_address() has been moved from cogl/{gl,gles}/cogl.c into cogl/common/cogl.c and this common implementation first trys _cogl_winsys_get_proc_address() but if that fails then it falls back to gmodule.

Adds the ability to build Cogl standalone This adds an autogen.sh, configure.ac and build/autotool files etc under clutter/cogl and makes some corresponding Makefile.am changes that make it possible to build and install Cogl as a standalone library. Some notable things about this are: A standalone installation of Cogl installs 3 pkg-config files; cogl-1.0.pc, cogl-gl-1.0.pc and cogl-2.0.pc. The second is only for compatibility with what clutter installed though I'm not sure that anything uses it so maybe we could remove it. cogl-1.0.pc is what Clutter would use if it were updated to build against a standalone cogl library. cogl-2.0.pc is what you would use if you were writing a standalone Cogl application. A standalone installation results in two libraries currently, libcogl.so and libcogl-pango.so. Notably we don't include a major number in the sonames because libcogl supports two major API versions; 1.x as used by Clutter and the experimental 2.x API for standalone applications. Parallel installation of later versions e.g. 3.x and beyond will be supportable either with new sonames or if we can maintain ABI then we'll continue to share libcogl.so. The headers are similarly not installed into a directory with a major version number since the same headers are shared to export the 1.x and 2.x APIs (The only difference is that cogl-2.0.pc ensures that -DCOGL_ENABLE_EXPERIMENTAL_2_0_API is used). Parallel installation of later versions is not precluded though since we can either continue sharing or later add a major version suffix.

Name: Cogl
Description: An object oriented GL/GLES Abstraction/Utility Layer
Version: @COGL_VERSION@
Libs: -L${libdir} -lcogl
2.0: Add cogl2-experimental.h + don't pollute .pc CFLAGS Instead of adding -DCOGL_ENABLE_EXPERIMENTAL_2_0_API to the cogl-2.0-experimental.pc file we now install a cogl2-experimental.h that #defines COGL_ENABLE_EXPERIMENTAL_2_0_API before including cogl.h. The problem with having the define in the .pc file is that you might develop a library that depends on the experimental 2.0 api internally and then you might want to use that library with Clutter which still uses the 1.0 API but the .pc file for your library will indirectly, automatically enable the 2.0 api which can cause conflicts.
