--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Can you provide the exact steps you are doing? Because I think you are misunderstanding how this works. So if you use --host=x86_64-w64-mingw32 . configure:2358: checking build system type configure:2372: result: x86_64-pc-linux-gnu configure:2419: checking host system type configure:2432: result: x86_64-w64-mingw32 configure:2452: checking target system type configure:2465: result: x86_64-w64-mingw32 But it uses the wrong compiler for the target libraries. Also I see you had built the cross compiler in the src directory: Configured with: ./configure --disable-libstdcxx-verbose --disable-multilib --disable-nls --enable-fully-dynamic-string --enable-languages=c,c++,lto --enable-large-address-aware --enable-mingw-wildcard --enable-threads=mcf --target=x86_64-w64-mingw32 Don't do that.
