You should try with libgl-devel based on this

[thomasarsouze]

Not sure I get this right.
From description of the package and cdt recommandation, it seems to be the right approach.
However I don't think I'm getting the difference between mesa-libgl-develand libgl-devel because the last one is not the one we're targeting.

Also not sure to understand why build is fine on 2/4 system

[AurelienBesnier]

The problem is that this package is for aarch64 which is the same thing than arm64 (another architecture we could support) more on those here and there. It's mostly used for android phones or smaller/modern laptops in general.
The {{ cdt('mesa-libgl-devel') }} thing is, from what I understand going to look what your conda install is (from miniforge github):

OS	Architecture	Minimum Version	File
Linux	x86_64 (amd64)	glibc >= 2.17	Miniforge3-Linux-x86_64.sh
Linux	aarch64 (arm64) (**)	glibc >= 2.17	Miniforge3-Linux-aarch64.sh
Linux	ppc64le (POWER8/9)	glibc >= 2.17	Miniforge3-Linux-ppc64le.sh
Linux	riscv64 (rv64gc) (***)	glibc >= 2.29	Miniforge3-Linux-riscv64.sh

and get the corresponding cdt package (eg. mesa-libgl-devel-conda-ppc64le, mesa-libgl-devel-conda-aarch64, etc...)

Those are still cdt packages. Since we are trying to get rid of them, we should use libgl-devel which from its description is the:

GL Vendor-Neutral Dispatch library

and its supported platforms are:

linux-ppc64le
linux-64
linux-riscv64
linux-aarch64

[AurelienBesnier]

everything seems to work now, only the macos-latest is not checked rn because the runner seems to be in high-demand

[AurelienBesnier]

I guess everything works now

[thomasarsouze]

Great work !
Not that great to pin an exact version of a dependency. Could we instead pin sip to a minimal version (>=6.10) ? Can you set somewhere why do we need this version ?

Also, in pyproject.toml, we should be consistent and set the same minimal version of sip in the dependencies.

[AurelienBesnier]

the sip version should actually be <=6.10 because more recent version will try to more recent version of the pyqt-sip bindings at runtime. The versions of everything sip is kinda broken on conda, which is why I tried to use pip instead but on the conda build, it wouldn't use pip to install the deps. I don't really know why
