Initialization problem of shared library in HP-UX11

[gother]

Thanks again for your reply.

I used gcc compiler. I tried once using ld to build the shared lib and
found that even the executable main linking to this shared lib doesn't
do the initialization properly.

Yes, I definely need a HP developer expert.

Gother
