[question] something searching for libglvnd using pacman on windows.

[TrevorCash]

What is your question?

Hello All,

I get the following error when calling conan install on windows. something is specifying libglvnd as a system dependancy using pacman (but this is not an msys2 package). Is there a way of narrowing this down? Fixing it?

Thanks for your report @TrevorCash

The relevant line would be

conan/conan/tools/system/package_manager.py

Line 48 in 7179562

"pacman": ["arch", "manjaro", "msys2", "endeavouros"],

This implements that pacman is the default package manager for msys2 environments. It is true that line

conan/conan/tools/system/package_manager.py

Line 40 in 7179562

elif os_name == "Windows" and self._conanfile.conf.get("tools.microsoft.bash:subsystem") == "msys2":

is not that evident that it should use that conf, but the os.subsystem setting.

While we have a look, you can use the conf tools.system.package_manager:tool to explicitly define which system package manager you would use, if it is a Windows machine, maybe none or chocolatey could do the job

I am proposing changing this for next Conan 2.9 in #17103, as a fix, I think it makes sense.

Thanks for your feedback!

#17103 was merged, it will be included in next Conan 2.9

Note in the meantime you can force the tool to use with the conf tools.system.package_manager:tool=choco to avoid the errors.
