New comment by jrigg on void-packages repository https://github.com/void-linux/void-packages/issues/25839#issuecomment-717783252 Comment: I got the Motif ICS version to compile on Void x86_64 glibc a while ago, but didn't try it with musl. The Alpine motif package uses the ICS version, so I guess it's possible. My motivation for using ICS motif is that I use the Snd audio editor, which doesn't work well with lesstif. (Until recently Snd could use either Motif or GTK, but GTK support was removed in the current version. I always used the Motif version anyway as it worked better).
