Hi Guys!

I try to profile my code on Ubuntu, and it seems to not work.

I read on the troubleshooting forum the posts, and I tried the suggestions, but with no results.
Can somebody help me, please?

Many thanks beforehands

You 're right, that is a mistake.
Linux doesn't need libgmon.a (I don't think it even exists)...
Will fix it. Thanks for the info

If you need to fix this yourself, edit plugins/compilergcc/compilerMINGW.cpp and remove "-lgmon" from the line where "Profile code when executed" is defined...
I will add a conditional there for non-windows platforms.

Thanx.

I made the mentioned modification on C::B, but still no results. 
The line that we're talkin' about is:
   m_Options.AddOption(_("Profile code when executed"), "-pg", _("Profiling"), "-pg - lgmon");
which is in plugins/compilergcc/compilerMINGW.cpp at line number: 82

Currently this line in my C::B looks like:
   m_Options.AddOption(_("Profile code when executed"), "-pg", _("Profiling"), "-pg");


The error message that I get with the newly compiled C::B is the same, as in the previous post.

Check your project's linker options. The option to link gmon must be left there. You should remove it yourself...
