llvm dev - Feb 2011 - [LLVMdev] llvm-gcc-4.2.-2.8 failed on gcc 3.4.6

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

-Wno-variadic-macros is only understood by GCC 4.0 and above.

Did you switch your compiler without re-running configure?
(configure checks that the compiler understands -Wno-variadic-macros,
among others)

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.
