Hi. I've noticed that the `mesa' package we provide is missing some symbols that according to the OpenGL specification should be present on the `libGL.so.1` library.
The following commands demonstrate the issue: --8<---------------cut here---------------start------------->8--- $ guix build mesa /gnu/store/ds15k8bzqf1m861w17hshd8i54pffig9-mesa-23.1.4-bin /gnu/store/hxvp1sp897rnnpbpb0xk887m4822gf77-mesa-23.1.4 $ nm -gD /gnu/store/hxvp1sp897rnnpbpb0xk887m4822gf77-mesa-23.1.4/lib/libGL.so.1 | grep glBindTextureUnit $ glxinfo | grep "OpenGL version" OpenGL version string: 4.6 (Compatibility Profile) Mesa 23.1.4 --8<---------------cut here---------------end--------------->8--- As you can see the grep does not match any symbol. In contrast, if we do the same under an Ubuntu installation, we can see the following output: --8<---------------cut here---------------start------------->8--- $ nm -gD /usr/lib/x86_64-linux-gnu/libGL.so.1 | grep glBindTextureUnit 0000000000046b60 T glBindTextureUnit 0000000000046b80 T glBindTextureUnitParameterEXT $ glxinfo | grep "OpenGL version" OpenGL version string: 4.6 (Compatibility Profile) Mesa 23.0.4-0ubuntu1~22.04.1 --8<---------------cut here---------------end--------------->8--- This symbol is also present on the `libGL.so.1` provided by the proprietary Nvidia driver: --8<---------------cut here---------------start------------->8--- $ guix build nvidia-driver /gnu/store/8xhdq3rf9k80n6vz5cwi7z1dg5wjq002-nvidia-driver-515.76 $ nm -gD /gnu/store/8xhdq3rf9k80n6vz5cwi7z1dg5wjq002-nvidia-driver-515.76/lib/libGL.so.1 | grep glBindTextureUnit 00000000000476c0 T glBindTextureUnit 0000000000047700 T glBindTextureUnitParameterEXT $ glxinfo | grep "OpenGL version" OpenGL version string: 4.5 (Compatibility Profile) Mesa 23.1.4 --8<---------------cut here---------------end--------------->8--- I've noticed the problem because I'm packaging a rust up that I wanted to contribute as an example on how to build applications that use meson to build rust packages. This app uses `rust-minidl' to load `libGL.so.1` at runtime. The app tries to use the `glBindTextureUnit` symbol and panics. Does anyone know why this symbol could be missing? Could we fix the `mesa' package? I would like users of the open source drivers to be able to run the package. Thanks, Sergio.
