How did you compile (or try to compile) the sources ?
If I use C::B to compile C::B it does not work, but if I do it from command-line there's no problem.
Just type (in root of the C::B source-tree):
./bootstrap
./configure --enable-contrib
make
make install
I only tried it until make, because I have latest nightlies installed as deb-Packages, build from svn, but it works like a charm.
I used a fresh download from svn4483 in a clean directory.
Edit:sorry it works, even from inside codeblocks. I forgot to change my standard compilers, before I started C::B. It does not work with gc-4.3 from debian-experimental, I use a shell script to switch to 4.2, I ran it before commandline compiling, but not before starting codeblocks.
