But it is loaded when I want to set the breakpoint. I can see the
source file, set a breakpoint in it, but it doesn't work. I opened the
gdb console (thanks for the suggestion), and I see warnings like
Warning - No location found for "x11gui.cpp:300"
when I try to set a breakpoint in rgl. How do I tell it where to find
the location corresponding to that file?
