Hi Pedro: I think there are some specific CMake options for making sure the -g option is used on all compilations, but the one I always use is to set the appropriate environment variables (which CMake recognizes as well). So before executing cmake in an initially empty build tree do something like the following: export CXXFLAGS=-g export CFLAGS=-g export FFLAGS=-g I always just use the command line to build (with make) and debug (with gdb) rather than some IDE like QtCreator, but I assume setting the above environment variables will insure the QtCreator builds will be done with the -g option so that you can debug (likely with gdb doing the work in the background) with that IDE as well.
