Since the issue of "what do I link against" pops up constantly,
despite there being a documented policy for this, and reams of closed
out falsely reported bugs in the Deban Bug database about libguile not
linking with libqthreads, I'll write up what I put in all the bug
reports.
The proper way to do this is to use guile-config. So for tortoise2.c
wen you compile and link in the same step try this:
gcc `guile-config compile` -L/usr/X11R6/lib -lX11 \
`guile-config link` tortoise2.c -o tortoise2
On a Debian box you get the following:
gcc -I/usr/include -L/usr/X11R6/lib -lX11 \
-L/usr/lib -lguile -lqthreads -ldl -lm tortoise2.c -o tortoise2
This is the recommended way for several reasons. The most pressing
are that it is portable across machines that both support and don't
support qthreads. This is important in Debian because some
architectures don't support qthreads.
If we areincluding compilation instructions in the tutorial, we should
prolly include the use of guile-config, otherwise we're just going to
be propogating problematic behavior some more.
