Dependency Analysis

Please note that this analysis is highly experimental. The aim here is to make maintenance easier by inspecting the package's dependencies. Importantly this analysis does not support optional dependencies, please double check those before making changes. If you do not want hinting of this kind ever please add bot: inspection: false to your conda-forge.yml. If you encounter issues with this feature please ping the bot team conda-forge/bot.

Analysis by source code inspection shows a discrepancy between it and the the package's stated requirements in the meta.yaml.

Packages found by source code inspection but not in the meta.yaml:

• pyopengl

Interestingly, this never happened before.

I reproduced the problem, and it does not seem related to the CMake version.

[traversaro]

A simple find_package(OpenGL REQUIRED) works, so probably it is something specific of how ign-cmake looks for OpenGL.

After investigating a bit more, it seems that a way to fix the problem is to add the {{ cdt('libglvnd-devel') }} dependency on Linux.

After investigating a bit more, it seems that a way to fix the problem is to add the {{ cdt('libglvnd-devel') }} dependency on Linux.

Apparently that package is not avalable in centos6, see:

conda_build.exceptions.DependencyNeedsBuildingError: Unsatisfiable dependencies for platform linux-64: {MatchSpec("libglvnd-devel-cos6-x86_64")}

Probably I think it is fine to just update to centos7 here, as other key packages for the typical robotic users are on centos7 (see conda-forge/opencv-feedstock#346) and in general I think centos6 compatibility is just relevant for some specific niche HPC users that I do not think are users of this package, see conda-forge/conda-forge.github.io#1436, https://conda-forge.org/docs/user/announcements.html#centos-7-docker-images-are-now-the-default, robotology/robotology-superbuild#929 for the context.

@conda-forge-admin please rerender

I also reported the strange behaviour of FindOpenGL I found in https://gitlab.kitware.com/cmake/cmake/-/issues/24814 .
