Hello all,
    Below I include the description of a problem somebody in my office is
having. We have been searching in the mailing list archive but we couldn't
find any solution. The funny thing is the same module in my computer works
fine without any special linking, just including math.h. I saw a post from
Paolo saying that should be enough from gcc 2.95.2.
    I'm using gcc 2.95.3 and the same RTLinux kernel than my partner, but
with Mandrake 7.2. You can see below he's using newer versions of gcc and
Mandrake.
    Can anybody help us?. Thank you.
