Hi all,
I ported [1] wxruby [2] but am running into an issue wrt pthreads. The
wxruby library gets linked like this:
cc -shared `wx-config --libs` -Wl,--version-script,./version-script
-Wl,-soname,wxruby.so -L'/usr/local/lib' -Wl,-R'/usr/local/lib'
-L'/usr/local/lib' -Wl,-R'/usr/local/lib' -o wxruby.so <lots of objects>
-Wl,-R -Wl,/usr/local/lib -L/usr/local/lib -L. -lruby18 -lcrypt -lm -lc
with
$ wx-config --libs
-L/usr/X11R6/lib -L/usr/local/lib -liconv -L/usr/X11R6/lib -pthread -lwx_gt=
k2-2.4
ldd(1) says this:

And running a ruby program requiring wxruby I get this error:
/libexec/ld-elf.so.1: /usr/local/lib/libgthread-2.0.so.400: Undefined symbo=
l "pthread_getschedparam"
When I link the library with -lpthread instead of -pthread ldd(1) has
this to say

and the module works fine. What to do? Why doesn't -pthread take care of
the situation?
