Re: [gtk-osx-devel] Gdk::Pixbuf::create(Gdk::Window, int, int, int, int) on Mac LION

[JIm Charlton <jim jimc dyndns org>]

Setting
os.environ["CXXFLAGS"]="-ggdb"
in .jhbuildrc-custom seems to do the trick if one puts --autogen --clean 
on the build line.  Or one can wipe out the source directory and let 
jhbuild reload it and run autogen etc with the new environment 
variable.  My error was setting CFLAGS and CXXFLAGS in my local 
environment rather than putting them in .jhbuildrc-custom (seems pretty 
obvious now!).

I will post again when/if I am finally able to get the debugger to step 
into the gtkmm library.
