[LLVMdev] Undefined references when LLVM is configured with "--host=x86_64-gnu-linux --target=x86_64-w64-mingw32"

[Jim Grosbach]

Hi Ruben,

Try adding a --build=x86_64-gnu-linux option to configure as well. I don't have that configuration locally, so I can't check to be certain, but IIRC, our configure wants all three for a cross compile like this.
