[cfe-dev] clang and scan-build help?

[Plank, Stefan]

Hello,

I found the hint t email to this email list and hopefully you can help me, because I don't know what is going wrong.
All seems good but no defekts are found and logged.
Just trying to use clang as valgrind alternative and scan-build for static code analysis together.

This I have done:

I checked out llvm, clang and compiler-rt and updated it with make update.

Then I did
        mkdir build
        (cd build && ../configure --enable-optimized && make -j 10 && make install)

After this I copied all files from
        /root/svn/llvm/tools/clang/tools/scan-build
to
        /usr/local/bin
where the installed files from clang are.

My linux kernel version is 3.3.2.1 und the llvm revision is 154805

I did a maven profile using clang and scan-build

But on screen every time this message is logged:

[exec] scan-build: Removing directory '/tmp/scan-build-2012-04-16-1' because it contains no reports.

Even if there are placed errors no report is done?
Can you tell me my mistake and what I have done wrong?
