Vtune and MinGW

Wed, 04/11/2012 - 05:08

I have problems using Vtune Analyzer to profile a an open source project (the origami tool TreeMaker to be specific) which has been build using the MinGW-Compiler for the Win-64-bit plattform. When building the project I have specified the compiler flag "-g3". In the vtune project settings I have specified the directory which include the source files.

After runing the VTune analyzer I see a call stack full of [treemaker.exe] and no function names. An when clicking on one of these items I get an error "Failed to show source and assembly code." How can I get more information what is going wrong? Does anyone have experience with using VTune in combination with MinGW? Thanks, Constantin

Hi Constantin,

You are not alone.

This is a known issue, and treated as "new feature request".

Hi Peter, ok, this is good to know. Can you tell me what the problem exactly is? Does Vtune not understand the debug symbols written by gcc? Regards, Constantin

Yes. VTune doesn't recognize debug infogenerated bymingw gcc...that is a new feature request.

Hi Peter, thanks for clarification. However, I am still a little confused: mingw supports different debug standards- f.e. stabs, dwarf-2. And as far as I know VTune also supports those standars - or is it just the linux version which supports them? Regards, Constantin

Hi Constantin,

You are right, again:-)

MinGW produces DWARF format.The toolsupports DWARF on Linux, but not for Windows PE executable format.

This is a new feature request.

Any update on this? I tried profiling a gcc target on windows, and noticed I am at least getting mangled function names and can look at the assembly, but not at the source code. P.S. can the status of feature requests like this be tracked somewhere?
