2.1 extension errors on Solaris/gcc

[Andrew Dalke]

Hello,

  An extension module I develop isn't building under Python 2.1
on a Solaris box which has gcc installed but not the vendor's
cc.  I can't figure it out.  Looking for advice.

Original attempt was to compile Python with gcc 2.95 using
the archive from ftp.sunfreeware.com .  That caused a problem.

 solana> /usr/local/bin/python
 Python 2.1.1 (#1, Aug 25 2001, 04:37:28)
 [GCC 3.0.1] on sunos5
 Type "copyright", "credits" or "license" for more information.
 >>> import cStringIO
 Traceback (most recent call last):
   File "<stdin>", line 1, in ?
 ImportError: ld.so.1: /usr/local/bin/python: fatal: libgcc_s.so.1:
 open failed: No such file or directory
 >>>

and there was no libgcc_s.so anywhere on the machine.

Next was to upgrade to gcc 3.0.1.  That compiled Python just
fine, but there were problems with the extension.

Now what?
