Hi,
I got the following error message when I try to compile llvm-gcc with gcc 3.4.6:

cc1plus: error: unrecognized command line option “-Wno-variadic-macros”
make[3]: *** [llvm-main.o] Error 1

Someone have an idea ?

thanks

Yes, C++ parts of llvm-gcc are built via your system compiler which
does not support this option.
Current workaround is either to upgrade compiler or hack the makefiles
to remove this option.
