Re: [Gnash-dev] setting breakpoints in a supporting library

[dww]

I followed the order you mentioned from a console window

set args  [command line arguments from use of writelauncher]
tb main
set breakpoint pending on
run

at this point the symbols for libgnashbase-trunk.so were not loaded
and when I set a pending breakpoint with the br command it still does
not get hit.

What else am I missing at what point are the symbols for
libgnashbase-trunk.so loaded in your scenario?

Thanks
Dennis
