I used popen specifically to allow you continue debugging while keeping the dot
process open and functional. That would be restored with adding a '&' after
the command but then we race with the file removal ...
The following works for me though:
# Show graph in temp file
os.system("( dot -Tx11 %s; rm %s ) &" % (filename, filename) )
dot_fn()
ok for trunk with that change and thanks for the help!
Now if the TDF_ flags were available in gdb (without -g3) that would be
awsome. I guess moving them into a enum would work but also require
some extra casts everywhere...
Thanks,
Richard.
