The “-gnu” in your devkit path is a sign that it’s likely a devkit for the GNU C library. You’ll need to grab or create one for aarch64-linux-musl instead.

Sorry, this is wrong. I should have gone to sleep instead. The -gnu is of course for the build platform where the compiler is running, so given that you have glibc installed on your build machine that should work just fine. You do still need to make sure is that the cross compiler creates binaries for musl though. I’m not sure how the linaro devkit you’re using handles that. There may be some argument to gcc/g++ you need to specify if it doesn’t happen automatically. If some explicit argument is needed it would be nice to have the (portola) autoconf/make files do so automatically.

Cheers,
Mikael
