> Can you tell me a more elegant solution to this ?(if there is). If not at least
how can I do this more automatically? Now I do some steps manually(like going
to /tmp and modify that file and recompile it and relink).

For the shared library dependency order see PR 33704.  The PR includes a patch,
but we never reached a final resolution and copyright assignment to include the
patch.

the shared libraries with makeCCSharedLibs, and I think (not 100% sure )the
library got first initialized.

xlC now uses a program instead of a script. It generates some code to
explicitly run constructors in the right order and does not rely on AIX
semantics.
