I noticed when debugging a segfault, even though my binary was linked to
the Qt_debug libraries no line numbers or other symbols were available.
My investigation found that no -g flags were passed to the
Makefile.Debug LFLAGS, thus when the shared library was built the
symbols disappeared.
I added the flags (-g -gdwarf-2 like what was in CXXFLAGS) and rebuilt
Qt and retried my gdb session. I got symbols, line numbers, code
listings, etc.
Given that the Makefiles are generated from the qmake project files, is
the bug in the way that they are generated or is this an upstream
problem with the Qt release?
The port was qt4-mac @4.7.4_0+debug+quartz
Cheers,
