Message-ID: <39F5AACB.1501EF5F@argo.es> Date: Tue, 24 Oct 2000 17:29:15 +0200 From: Jesus Cea Avion <jcea@argo.es> Organization: Argo Redes y Servicios Telematicos, S.A. - http://www.argo.es/ Newsgroups: comp.lang.python To: mod_python@modpython.org Subject: BUG compiling Python 2.0 with dinamic modules in Solaris, with GCC
(I can't post the patch in sourceforge since the SSL login seems to be down in the last three hours)
Python 2.0 (dinamic modules)
Mod_Python 2.6.2 (dinamic module)
GCC 2.95.2
Apache 1.3.14 (dinamic modules)
SunOS5 (Solaris 2.x)
I send the email also to "mod_python" mailing list since I detect the problem using this package. Other developers could see the very same problem!.
Mod_python runs smoothly until I do a "import zlib", for example, in a handler. In this case, the request is aborted with the following log:

<<<<<
That is, "zlibmodule.so" tries to link to a function called "main".
Doing a "nm object | grep main", I see the unresolved reference in "zlibmodule.so", but not in "zlibmodule.o". So, the problem seems to be the creation of the shared library.
I tracked down the problem to the "configure" script: "cc -G" is (I think) the right thing to do to create a shared library if you are using the Sun compiler, but if you are using GCC (like me), the right command is "gcc -shared".
Patch for Python 2.0:
