For several reasons I have to use STLport on a HPUX 11 (PA_RISC). I
downloaded Version 4.6.2 and compiled it using the hpacc-Makefile
without any errors. The resulting libs are now in /usr/local/lib and
the headers in /usr/local/include/stlport.

Now I want to use this lib in a program. I took the sources and the
makefile from another HPUX machine. It compiled and linked very well
but when I start my program it says:

/usr/lib/dld.sl: Unresolved symbol: [Vtable]key:__dt__Q2_3std9exceptionF
v (data)  from /usr/local/lib/libstlport_aCC.sl
/usr/lib/dld.sl: Unresolved symbol: typeid__XTQ2_3std9exception_ (data)  fro
m /usr/local/lib/libstlport_aCC.sl
ABORT instruction (core dumped)

What does this mean exactly? I guess my shared lib assumes another lib
containing these symbols but I do not have one. But which one?

T.M.

It means that libstlport_aCC.sl depends on external symbols:
std::exception::~exception()
typeid<std::exception>

These come from /usr/lib/libCsup_v2.sl on my system.

That library should be automatically linked into your program,
provided you link with:

aCC -AA main.o ... -lstlport_aCC

I am guessing that you compiled libstlport_aCC.sl with the -AA flag,
but linking your main executable without -AA. You can't do that:
from "man aCC":

NOTE: Objects and libraries compiled with -AA are binary
incompatible with objects and libraries compiled without -AA.
