Re: Help needed to configure gdb


Thanks Jon. I tried that and in that case gdb launched kicad, but it couldn't find the source file to set a breakpoint. If someone can give me an example of setting the breakpoint that would be great. I tried relative path and full path, but still couldn't set the breakpoint in copper_zone_dialog.cpp.- Pradeepa Sent on the go with Vodafone
