Debugging wine with winedbg - wine-devel

21 May 2014


      I'm trying to debug Wine, and I want to step into the BitBlt function using
winedbg. I've set a breakpoint at BitBlt, and it is being hit, however,
when I list the source code, it points somewhere completely differently in
the source. I have no idea why that is. Does it mean that Wine is not setup
correctly for debugging?
I cloned Wine from Git a few days ago, and I've used "./tools/wineinstall"
to compile and install it.
This is an excerpt of the debugging session.
