Using Clang as a cross-compiler, build on Windows for Linux x86_64

Hello,

I’m currently trying to get Clang to work as a cross compiler in order to enable my colleges to compile the code for Linux (x86_64) on Windows. So far I have a working version GCC to cross compile my, so I have access to the native linkers and binary tools on Windows.

I’m currently using the windows snapshot build of clang and I’m trying to compile a simple hello world example in both C and C++. I invoke clang as follows:

clang --target=x86_64-unknown-linux-gnu --toolchain= main.c

clang++ --target=x86_64-unknown-linux-gnu --toolchain= main.cpp

At the moment I have the following issues:

  1. I am unable to use the stdlib++ from the cross compiled GCC, am I missing a flag?

  2. I am unable to link the final binary for the C example, clang crashes with the following output: http://justpaste.it/dnpb

In theory this should work right? Clang compiles the code to LLVM IR and then uses the native linker to generate the object files, as far as I can tell from the documentation. Or, should I compile Clang from source on Linux, just like I did with GCC in order to have a working cross-compiler?
