Does this pthread(?) crash ring any bells?
Hi!
I'm still trying to port Paul Barton-Davies' splendid quasimodo program
(http://www.quasimodo.org) to a Debian PowerPC system with a view to
making a deb package of it. I've had to install some libraries from
Woody and elsewhere, namely:
libgtkmm_1.0.3-1.1.deb
libsigc++0_1.0.1-1.deb
libsigc++-dev_1.0.1-1.deb
libxml-dev_1.8.9-1.deb
libxml1_1.8.9-1.deb
With help from Paul, the program now compiles and (outside of gdb)
starts well enough, but it is easy to make it crash. Running it inside
the debugger makes it crash instantly (gdb will debug multi-threaded
programs, right?). I'm using the phtread library which came with
Potato, 0.8, and gcc/g++ 2.95.2. I am worried that the problem is in
the pthread library because of what the debugger tells me (at end). I
know this package compiles and runs on quite a few other architectures
(and will be trying it out on GNU/Linux Intel i386 soon) but need it to
work on PowerPCs because somebody senior went and bought 10 of 'em to
put in my Lab before I arrived here 8-)
Another thing, it seems some bug numbers you guys talk about don't
appear in the bug list at http://www.debian.org/Bugs/db/ix/full.html
-- do you have your own? Sorry, but I've not been able to find it...
Many thanks for your attention!
