[LLVMdev] compiling llvm-gcc4 on ubuntu

[Stefan Weigert]

hello,

i am new to llvm and can't manage to compile the gcc backend.

my steps:
i compile the llvm-source first as suggested in "README.LLVM"
that works fine and without any issues.

then i make a new dir called build. from there i do the following:

stefan at ubuntu:~/programs/llvm/build$ ../llvm-gcc4-1.9.source/configure --enable-languages=c,c++ --prefix=/usr/local/ --disable-shared
then after some time i get the follwing error:

make[2]: Entering directory '/home/stefan/programs/llvm/build/gcc'
