I expect that at compilation time we get the right headers,

<pre wrap="">If you check this at build time, the resulting glamor binaries will only
work with the same EGL/gbm implementation they were built against, won't

<pre wrap="">Thanks for raising the question. I could not find a non-mesa
implementation. Strictly from a package configuration point of view, it
is acceptable to limit what the package can cope with. I suspect
glamor_egl.c cannot handle unknown EGLNativePixmapType(s).
It is generally preferred to detect problems early in the configuration
rather than at build time or at runtime. Whether glamor should be able
to support all current and future implementations is a separate discussion.

I think I found a non-mesa implementation, reading the patch "GLX:
Enable glx support."<br>
<blockquote>"If you are not using normal MESA, for example PVR's
private GLES
implementation, then it should be ok to use GLES2 glamor and the
GLX should work as expected. In this commit, I use gbm to check
whether we are using MESA or non-mesa. Maybe not the best way."<br>

That would be the PowerVR INsider SDK
