Compilation error: unknown type name ‘PFNGLGETINTEGER64VEXTPROC’ in fx_renderer.h

[RegisAttila]

Hi,

I'm encountering the following compilation errors when building the project:

../include/render/fx_renderer/fx_renderer.h:174:17: error: unknown type name ‘PFNGLGETINTEGER64VEXTPROC’
174 | PFNGLGETINTEGER64VEXTPROC glGetInteger64vEXT;
../render/fx_renderer/fx_pass.c:78:17: error: called object is not a function or function pointer
78 | renderer->procs.glGetInteger64vEXT(GL_GPU_DISJOINT_EXT, &disjoint);
../render/fx_renderer/fx_pass.c:82:17: error: called object is not a function or function pointer
82 | renderer->procs.glGetInteger64vEXT(GL_TIMESTAMP_EXT, &timer->gl_cpu_end);

It seems that the type PFNGLGETINTEGER64VEXTPROC is not defined, causing subsequent calls to glGetInteger64vEXT to fail.

Could you please advise on how to fix this or whether there is a missing dependency or OpenGL extension that needs to be enabled?

Thank you!

You need to install the gles2 dependency (glesv2). In fedora just run sudo dnf install "pkgconfig(glesv2)"

Thanks for the tip!
I'm on Ubuntu and I already have what I believe is the equivalent package installed (libgles2-mesa-dev).
To check, I ran:

pkg-config --modversion glesv2

and it returned:

3.2

So it seems the package is present, but I'm still encountering the same error.
Could there be other dependencies or steps I might be missing?

Thanks again for your help!

Try these: https://packages.debian.org/experimental/libwlroots-0.19-dev

Thank you for the suggestion.
I’m currently running Ubuntu 22.04 Jammy, and it seems that the libwlroots-0.19-dev package is not available for this distribution. I have installed the standard wlroots version 0.19, but unfortunately, the build still fails with the same errors.

From what I understand, some dependencies like libdisplay-info-dev and libliftoff-dev required by wlroots 0.19 dev are not available in Jammy’s official repositories, which might be causing the issues.
Thanks again for your help!

There is a list of dependencies that are required by the wlroots devel package that might be of interest :)
