Created attachment 764007 [details] Build log When building wpa_supplicant on a powerpc musl system it complains about undefined references to bswap16, bswap32 and bswap64. This is only exposed when adding the -meabi cflag which is recommended for targetted system however when building without this flag it does compile but wpa_supplicant will not connect to any wireless network. # emerge --info Portage 3.0.28 (python 3.9.9-final-0, default/linux/ppc/17.0/musl/hardened, gcc-11.2.0, musl-1.2.2-r6, 3.15.10ngx+ ppc)

No idea what this is, but use of -meabi is wrong. It is an ABI-changing option and is not an ABI supported by musl. Where did the recommendation to use such an option come from? If some libraries on the system have been compiled with -meabi, that's very likely the cause of your breakage in the case where the build succeeded. If there's still a problem you should open a bug about failure to connect, rather than about mixing unsupported ABIs failing at build time, which is to be expected.
This is building on a Nintendo Wii so it's in the documentation on GCLinux (from memory). I'll build a test system without -meabi and see what happens, I'll update this bug once I have those results.
After spending some more time with it, removing -meabi from the whole build seems to fix the issue so I'll mark this resolved.
