I'm experimenting with embedding Python in C++ programs as explained
in http://www.python.org/doc/current/ext/embedding.html.  I'm having
some trouble linking, however.

I'm running an i686 system with Red Hat 8, using gcc 3.2 and Python
2.2.

The C++ program is:
-----
#include <python2.2/Python.h>
int main()
{
  Py_Initialize();

  PyRun_SimpleString("print \"Hello, world!\"");

  Py_Finalize();
  return 0;
}
-----

It compiles cleanly, but can't resolve linking:
$ g++ hello.cc -o hello
/tmp/ccGyP0Vj.o: In function `main':
/tmp/ccGyP0Vj.o(.text+0x11): undefined reference to `Py_Initialize'
/tmp/ccGyP0Vj.o(.text+0x1e): undefined reference to
`PyRun_SimpleString'
/tmp/ccGyP0Vj.o(.text+0x26): undefined reference to `Py_Finalize'
collect2: ld returned 1 exit status

A grep in /usr/lib/python2.2/ yields:
$ grep "Py_Initialize" * */*
Binary file config/libpython2.2.a matches

But, I've attempted to add libpython2.2.a in a few ways to g++, to no
avail.

Anyone have any help?

Thanks!
Ian
