How to debug a plugin?

<< < (2/2)

cyberkoa:
I used to use wxMessageBox to debug but now this time I need to use the GDB to debug. I still couldn't get the way to debug wxSmith .. but I really a newbie in debugging C++ GUI program  ..

I have tried to toggle a break point at ScanForPlugins() at main.cpp and press F4 to let the program run to cursor .

another CB instants running , and I try to check the message , the 10 plugins have been loaded , and the keybind has also been loaded  :shock: ? the program does not stop at breakpoint ?

I check the Debug menu, only Debug Windows and Stop debugger are not grey , cannot press continue /step over/step into.

Since wxSmith has a different project file , how should I do the debug ? I load the CB project file and toggle the breakpoint at ScanForPlugins and load wxSmith project file , toggle the break point at wxSmith source , is it correct ?

...when this happens to me I usually had forgotten to enable the "-g" debug compiler switch and/or forgotten to do a full re-build with the new settings. It's an obvious thing but maybe it happened to you as well...?!

The debugger in SVN HEAD supports putting a breakpoint *anywhere*, even in DLLs. No need to break on ScanForPlugins or anywhere else. Just put a breakpoint where you need it and press F8.

I just want to clarify that "*anywhere*" does not include C++ constructors with gdb.exe. I 'm still converting the hack we used for this...
