[cfe-dev] Using ccc with an absolute path

[Moritz Lenz]

Hi,

I tried to compile the parrot virtual machine
(http://www.parrotcode.org/) with llvm-gcc, but utils/ccc always aborts
with 'OSError: [Errno 2] No such file or directory'


perl Configure.pl --verbose \
--cc=/home/moritz/tmp/llvm/tools/clang/utils/ccc
Parrot Version 0.7.0 Configure 2.0

Compilation failed with '/home/moritz/tmp/llvm/tools/clang/utils/ccc'

I manually tried to compile the file (test_3685.c) by going to
the llvm dir and then running tools/clang/utils/ccc $file (and I tried
it from tools/clang as well) and always got the same error. This feels
like some stupid path problem, which I can't seem to figure out; any ideas?

I built llvm+clang as described on
http://clang.llvm.org/get_started.html in the section "Building clang
while building llvm", revision is r55495, on Debian GNU/Linux i386 (32 bit)

Any ideas how I can get ccc to work for me?

Cheers,
Moritz
