OK, I think I found the right way: I selected "Project" and "Set programs' arguments". In the "Select target" window I set the "Host application". But if I start debugging I get this message:
Setting breakpoints
Debugger name and version: GNU gdb 6.7.50.20071127
No symbol table is loaded. Use the "file" command.
No symbol table is loaded. Use the "file" command.
And I found this in the debuggers log:
>>>>>>cb_gdb:
> break "E:/........./myfile.cpp:41"
No symbol table is loaded. Use the "file" command.
I compiled by DLL with -g and (to be realy safe) -ggdb. Sure, Winamp is compiled without debugging symbols. Is this the problem? The Winamp Team told me to ignore the message that symbols are not loaded (if I would use Visual Studio) but I can't find an option to set it for gdb.
Any idea?
