You do need to build LLVM first before building llvm-gcc. This may seem
a bit weird, but here's what's going on:
1. All of the LLVM tools build without llvm-gcc/llvm-g++. So, if you
run configure and then build LLVM with "make tools-only," it will
build
all of the LLVM tools. You'll get a warning from configure telling you
that it cannot find llvm-gcc. This warning is benign and can be ignored.
2. Next, build llvm-gcc/llvm-g++. The compiler will invoke gccas and
gccld (built in step 1), so you need to make sure that the LLVM tools
are in your $PATH.
3. Now you have the LLVM tools and the llvm-gcc/llvm-g++ compiler.
However, there are some libraries in the LLVM source tree (in
llvm/runtime, to be exact), which need to be built by llvm-gcc.
So, go back to the LLVM source tree and re-run configure so that it can
find the llvm-gcc/llvm-g++ binaries (which you should put into your
$PATH). Then, go into llvm/runtime and run "make install-bytecode".
That will build the remaining bytecode libraries and install them into
the llvmgccdir/lib directory.
That should be it. Please let us know the above does not work.
