Subject Re: Use GDB but no debugging symbols found
Date Tue, 20 Aug 2013 12:20:37 GMT
Apache OpenOffice uses both dmake and gnu-make build systems. We know
that is a PITA and the project will clean this historical mess up in the
future.

Enabling debug symbols is done by using a "debug=1" parameter in the
module of interest. For dmake modules you do
   build killobj ; build debug=1
in that module. For gnu-make modules you do
   make clean ; make debug=1
in that module.

The first command in each line makes sure that the object files are
removed so the source file gets recompiled.
