Re: hpux linking shared library with static library

[Alon Bar-Lev]

‎‎Thank you!

But I do link the static library as PIC.

Attached is a sample.

When I remove the restriction all  works, shared can call static, main
can call both.

         =>
        /usr/lib/libc.2 =>      /usr/lib/libc.2
        /usr/lib/libdld.2 =>    /usr/lib/libdld.2
        /usr/lib/libc.2 =>      /usr/lib/libc.2
        /tmp/alon/test-1/xxx/lib/libb.sl =>     /tmp/alon/test-1/xxx/lib/libb.sl
        /usr/lib/libc.2 =>      /usr/lib/libc.2
