I'm sure that's not the only thing preventing Nokia from switching to
MinGW-w64... although this is the first I've heard of slow startup of gdb.
I never use it (never seems to work quite the way I want it to, but that's
me being debugger-incapable). Could you give me a reproducible example (and
a gdb which works without the slow startup)? Maybe I could see where the
difference comes from (or at least ask around). Have you tried 32-bit vs
64-bit as well?
And thank you for promoting my builds :) It would indeed be awesome to have
Qt switch to MinGW-w64. I've been making sure all of it keeps working
(err.. building) since 4.7. If anyone asks for help with anything
build-related, feel free to redirect them to this list!
