I've got yet another problem with C++ and GCC here.  I have written a
small 3D library type thing (:) which worked fine in DJGPP, but when I
ported it over to Linux I've all of a sudden run into problems.  When I
compile I get the following errors:

/lib/libstdc++.so: undefined reference to 'fabs'
/lib/libstdc++.so: undefined reference to 'log'
/lib/libstdc++.so: undefined reference to 'sqrt'
/lib/libstdc++.so: undefined reference to 'cosh'
/lib/libstdc++.so: undefined reference to 'cos'
/lib/libstdc++.so: undefined reference to 'sin'
/lib/libstdc++.so: undefined reference to 'atan2'
/lib/libstdc++.so: undefined reference to 'sinh'
/lib/libstdc++.so: undefined reference to 'exp'
/lib/libstdc++.so: undefined reference to 'hypot'

Those are all math functions, BUT I'm including math.h AND I'm linking
with libm!!!  What the hell else have I forgotten? :)

PLEASE help me out here.  I'm been trying my hardest to get some
portable 3D code going, but, as you can see, not everything is working
out as planned!

Thanks a lot,
Jeff

PS: As with my other message, it would be perfered if you could respond
via email if possible.
