Pretty obvious question/answer but thought I'd ask anyhow.
The Source Search path - my application pre-processes source files but puts the processed .c and .cxx files in a completely different path and directory tree from the source .C and .CXX files. I am sure the Source Search path should be to the post-CPP files, to the .c and .cxx files correct? It's a stupid and obvious question, but thought I'd be 100% sure on the answer.
VTune source search needs to find the source files which were actually passed to Intel C++. If you are using other tools to pre-process, VTune will be able to use the debug symbol tables only to refer back to the source actually seen by the compiler.
