IRC, OFTC, #debian-hurd, 2011-07-21.
<youpi> there's one known issue with pthreads
<youpi> you can't dlopen() it
<youpi> which also means you can't dlopen() a module which depends on it if
the main application hasn't used -lpthread already
<youpi> (so as to get libpthread initialized early, not at the dlopen()
call)
<lucas> I get this while building simgrid:
<lucas> cd /home/lucas/simgrid-3.6.1/obj-i486-gnu/examples/gras/console &&
/usr/bin/cmake -E create_symlink
/home/lucas/simgrid-3.6.1/obj-i486-gnu/lib/libsimgrid.so
/home/lucas/simgrid-3.6.1/obj-i486-gnu/examples/gras/console/simgrid.so
<lucas> cd /home/lucas/simgrid-3.6.1/obj-i486-gnu/examples/gras/console &&
lua /home/lucas/simgrid-3.6.1/examples/gras/console/ping_generator.lua
<lucas> lua:
/home/buildd/build/chroot-sid/home/buildd/byhand/hurd/./libpthread/sysdeps/generic/pt-mutex-timedlock.c:68:
__pthread_mutex_timedlock_internal: Assertion `__pthread_threads' failed.
<lucas> Aborted (core dumped)
<youpi> that's it, yes
<youpi> (or at least it has the same symptoms)
<lucas> it would need fixing in lua, not in SG, then, right?
<youpi> yes
<lucas> ok, thanks
