New comment by q66 on void-packages repository https://github.com/void-linux/void-packages/pull/25011#issuecomment-696439186 Comment: you should check if the ARM errors are cross-related (one thing i can think about: maybe the buildsystem checks for the header without properly accounting for cross sysroot? in that case you could workaround it by installing `glibmm-devel` on the host as well) i don't see anything bad for ppc, but i'll test it after it's merged, i just don't have time to deal with everything
