I’ve been trying to cross-compile an ARM microcontroller app with ELLCC. I first noticed that the x86_64 distro of ELLCC could compile for multiple architectures, but didn’t have libraries for all of them. I copied over the libraries from the ARM distribution, but I’m still missing three libraries:

libc++abi
libunwind
libclang_rt.builtins-armv7a.a

The last one sounds like it could be trouble, but I can’t figure out why the first two aren’t present anywhere.
