I'm basically thinking about OpenGL.h, GLX.h, etc for programs that wish to use new ABI, and glvnd{Foo,Bar}.h which mesa and other GL implementations. </pre> </blockquote> <pre wrap="">I haven't looked much into packaging yet. I'm open to any suggestions that might make that easier, though. One thing that I'm planning to do but haven't gotten to yet is to move the public headers into a separate directory. There's a couple of header files (libglxabi.h and GLdispatchABI.h) that are intended to be used by vendor library implementations, and the other headers are all internal. The headers that you'd use for compiling an application (gl.h, glx.h, etc.) could easily go into a separate package, too. </pre> </blockquote> <pre wrap="">By 'packaging' I meant that the relevant files are available after `make install'. Currently for GLdispatchABI.h and others that's not the case. We can leave it up-to the distributions to manage the actual packages (if in doubt a document to guide them), but we can make sure that the files (including pkg-config and cmake ones, separate set for user/developer) are there. </pre> </blockquote> <pre wrap="">The 'make install' command currently doesn't do anything with the regular GL headers. I would expect that if someone's building an OpenGL application, then they've probably already installed some version of the GL headers separately. Still, I could probably add a configure option or something to include them. </pre> </blockquote> <pre wrap="">Pretty much what I was wondering. Mostly as I've noticed that the official Nvidia driver has started shipping some headers which clash with mesa ones :'( Perhaps the AMD proprietary driver ships some as well ? </pre> <blockquote type="cite"> <pre wrap="">Including the public ABI headers in a "make install" does sound like a good idea. Maybe put them next to the normal GL headers, or under a GLVND subdirectory? </pre> </blockquote> <pre wrap="">A separate location sounds better imho. Then again this information will be made available via the .pc .cmake files. People that don't use them can hardcode thing as needed :) [snip] </pre> </blockquote> I agree that a separate directory from the other GL headers would be best. I'm leaning toward putting the libglvnd headers into a sibling directory to the GL headers, probably /usr/include/GLVND. Putting them in a subdirectory under GL (/usr/include/GL/GLVND) would also be an option. But eventually, libglvnd will have an EGL header there as well, and putting that under /usr/include/GL seems less appropriate. Does that sound like a good place for them? </body> </html>
