Do you have a plan to support LoongArch? #14146

Do you have a plan to support LoongArch?

memsharded commented 1 year ago

What do you mean to support LoongArch?

It is possible to define any architecture in your settings.yml or in your settings_user.yml: https://docs.conan.io/2/reference/config_files/settings.html#customizing-settings. So this wouldn't be a blocker, you can add it there and use in your recipes with self.settings.arch.

A different issue is if build-systems like CMake understand that architecture. It would be necessary to understand the possible gaps, compilation flags, architecture mapping that the different build systems (CMake, Autotools, Meson, etc would be doing)

Thanks for your reply.

It appears that autotools are not compatible with the Loongson platform. my settings_user.yml is

arch: [loongarch64]

It seems that you are in cross-building. That would happen if someone forget to tweak the defaut profile and then run with -pr <host-profile>. Try -pr:a <profile> instead, or manually specify tools.gnu:host_triplet and tools.gnu:build_triplet.

Thank you for your feedback. I'm pleased to hear that modifying the default profile correctly resolved your issue.
