hidden symbol __dso_handle reference: link error

hidden symbol __dso_handle reference: link error

[Gary Hughes-Fenchel]

I am seeing this:
  /usr/bin/ld: pgmreceiver: hidden symbol `__dso_handle' in
/usr/lib/gcc/x86_6
     4-redhat-linux/4.1.1/crtbegin.o is referenced by DSO
  26 /usr/bin/ld: final link failed: Nonrepresentable section on output
  27 collect2: ld returned 1 exit status

I am calling ld directly. I am building 2 separate libraries and trying
to link with the dynamic libraries. The libraries are being created with:
-fvisibility=default
-shared
-soname foo.so -lc mylib1.a mylib2.a

I don't have the option of either rebuilding the compiler (suggested in
one post at http://gcc.gnu.org/ml/libstdc++/2000-06/msg00134.html) or
ceasing to call ld directly. The version I'm using is:
g++ --version
g++ (GCC) 4.1.1 20070105 (Red Hat 4.1.1-52)

The linker I'm using is:
ld --version
GNU ld version 2.17.50.0.6-2.el5 20061020


Any assistance would be greatly appreciated.

Are you using '-shared' when you invoke gcc/g++ to compile your source 
objects?

No I was not. I tried it, and that cleared it up! Thanks!

Yes. I am attaching 3 files: BuildSmall, which is a bash script to build 
  the cpp files, reallysmall.cpp which contains main, and 
reallysmalllib.cpp which contains a call to stat & printf. I COULD have 
written a makefile but I think the bash script is even more trivial.

This apparently works using gcc 4.x, but not the version of gcc I am using.
  gcc --version
gcc (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-53)

Upgrading gcc is not going to be an option for the actual product.
