Hi there - I want to build a cross-compiler from Linux x86_64 (host) to AIX PowerPC (target). Eventually, while building gcc, I get: > collect2: fatal error: libgcc.a: cannot open as COFF file While Linux uses ELF and AIX uses coff, I would have assumed that the binutils I built for the cross-compiler would have produced a linker that was able to link COFF files. The configure for binutils was: > configure --disable-gold --prefix=/aix-powerpc --disable-multilib --disable-nls --target=powerpc-ibm-aix7.1.0.0 --with-sysroot=/aix-powerpc --with-arch=powerpc --disable-werror --enable-plugins where /aix-powerpc contains headers and libraries copied from a live AIX system. Apparently back in 2016 on this same mailing list: https://gcc.gnu.org/legacy-ml/gcc-help/2016-10/msg00108.html somebody was trying to build the same cross-compiler and got the same error. Unfortunately, there’s no answer there. The only advice given was: > Judicious use of "-v" can help spot calling the wrong linker, linking the wrong libraries, wrong header file include paths, etc. Can anyone perhaps give a _little_ more help? Thanks. - Paul
