Hi there,

Is it possible to use GCC 3.4 with LLVM 2.0? I tried to compile GCC 3.4 with LLVM 2.0 and get following error message:

Is it possible to use GCC 3.4 with LLVM 2.0? I tried to compile GCC
3.4 with LLVM 2.0 and get following error message:

No. LLVM 2.0 removed a lot of stuff that is critical to get llvm-gcc3 working (ie. runtime libraries). llvm-gcc3 also does not output the right syntax. Its a lot of work to get it working.

Why can't you use llvm-gcc4?
