[LLVMdev] Problems compiling llvm-gcc4 frontend on x86_64

Hi Warren,
you can try to configure with the following

export CFLAGS="-m64"
export LDFLAGS="-L/usr/lib64"

LLVM:
../src/configure --prefix=`pwd`../install --enable-optimized --enable-jit
--enable-targets=host-only
make

LLVM-GCC:
../llvm-gcc4-2.0.source/configure --prefix=`pwd`../install
--program-prefix=llvm- --enable-llvm=/home/warren/llvm/obj/
--enable-languages=c,c++ --disable-shared --disable-multilib

make

Sometimes the gcc you use to compile matters. I wasn't able to compile with
4.1.* for example. I use 4.0.4 right now.

Regards,
Ferad Zyulkyarov
