shared library create by hppa64-hp11.11 can't run.

work ok on gcc-3.4.6,buit failed on gcc4.1.2/4.2.1.

some symbol required by the shared library could not be found.

Can you describe more of the problem?
Also how about a testcase.

------- Comment #2 from cnstar9988 at gmail dot com  2007-07-20 05:25 -------
My library is a java native library.

It's was build by hp cc.
I have patch all as/ld patchs from hp site.

I read http://gcc.gnu.org/install/specific.html#hppa-hp-hpux11.
It's no doubt that I can build gcc myself.
I can build gcc 4.1.2 on AIX5.1/Solaris10/Linux26.

I use hpcc/gcc3.4.5 to build gcc-3.4.6, gcc 3.4.6 works ok to buid my
library.(Use Tomcat/hppa64 JDK)

Now I want to build it with gcc 4.1.2 or gcc 4.2.1.
I use gcc-3.4.6 or hpcc to build gcc 4.1.2 or gcc 4.2.1, --with-bootstrap.
the gcc builds my library ok.
But it can't work.
"some symbol required by the shared library could not be found"

I use nm -g to display the symbols, it's ok.

Mybe HPPA64 doesn't support weak symbols.

I download gcc-4.1.2/4.2.0 from hp-gcc, it works failed too.

I build with -lgcc_stub, So works ok.

I think "_Jv_RegisterClasses" for GCJ.
        "__cxa_finalize" for G++.

My Library only use C language, so works ok.

:)

------- Comment #8 from danglin at gcc dot gnu dot org  2007-10-14 16:23 -------
Regarding comment #4, I don't believe the warnings are a problem.  hppa64-hpux
does not support undefined weak.

Regarding comment #6, '-m64' is not a valid gcc option for the hppa64-hpux
target.  Thus, it appears littlestar is using a wrapper around 32 and 64 bit
gcc builds.  This is likely the cause of the problem.

I linked a simple test program with the command options given in comment #6
and didn't see the problem (i.e., -lgcc_stub is added to the link command).
You can see this by adding '-Wl,-debug' to the gcc command.

Regarding '_Jv_RegisterClasses' and '__cxa_finalize', these currently don't
do anything.  The stubs in libgcc_stub.a simply are there to satisfy references
to these routines generated in crtbegin.o.  These result from using the
generic crt code in crtstuff.c.  This could be avoided if we provided our
own crt code. 

'__cxa_finalize' probably will never be used.  However, '_Jv_RegisterClasses'
will be used when we complete porting libffi and libjava.  Since you are
porting a native java library, you may want to look at your own implementation
of '_Jv_RegisterClasses'.
