You want to pass the -g option to the compiler, to get gdb to emit source
file names and linenumbers. Most of the time something like this works:
/usr/ports/x11-wm/windowmaker# make CFLAGS="-g" STRIP="" all install
But this depends on whether the port honors your custom CFLAGS.
Note that usually you don't have to install the debug version, you can
also run the resulting binary from the work/windowmaker-0.xxx/...
subdirs.
Hope this helps,
