[LLVMdev] llvm configuration error

[Bo Wu]

The problem was solved by setting environment variable CXX. But somehow a
new one came. The gcc is installed in /usr/local/gcc-4.2.3. I managed to
change

clang/lib/Frontend/InitHeaderSearch.cpp

clang/lib/Driver/ToolChains.cpp

to force clang use the crt lib for that version. For details, plz see
http://www.advogato.org/person/redi/diary/228.html.

So now I have no problem of using clang to compile a trivial C program of
20 lines. When I tried to compile programs of spec2006, such as bzip2 or
mcf, the following erros showed up.

invocation)

Any suggestion would be greatly appreciated.
