Following message is displayed in the log file:
....
[Cppcheck] Starting the cppcheck analysis.
[Cppcheck] Processing 1 files with the pattern '**/*cppcheck.xml'.
[Cppcheck] [WARNING] - The source file 'file:/hudson/jenkins/jenkins/jobs/xxxx/workspace/ARCH/i386/DEBUG/false/binsrc/yyyyyy.cpp' doesn't exist on the slave. The ability to display its source code has been removed.

The result is, that the file has no link in the cppcheck results.

The cause is, cppcheck reports the file with an relatve path, binsrc/xxxxx.cpp, but the plugin search the file in the wrong path.
The local module directory should be added to the path if it exists (we use svn repository), it should look like
file:/hudson/jenkins/jenkins/jobs/xxxx/workspace/ARCH/i386/DEBUG/false/xxxx/binsrc/yyyyyy.cpp.
While xxxx is the local module directory, defined as optional scm subversion property.
