Our program that makes use of cx_Oracle and multi-threading (and works fine on Windows, Linux and other platforms, including HP-UX PA-RISC), fails to run on HP-UX Itanium. When trying to start the first daemon thread, the program raises an exception: ... File "/usr/local/lib/python2.6/threading.py", line 471, in start _start_new_thread(self.__bootstrap, ()) error: can't start new thread
I guess there's something wrong with the way we built Python, but I have absolutely no clue what (I'm not too familiar with HP-UX). >From what I found in the internet, it's probably something about the threading libraries at the C level. So the question is: Which steps are necessary to build Python 2.6.2 (32bit or 64bit) on HP- UX Itanium 11.31 with working multi-threading support? Note: For whatever reasons, in order to get cx_Oracle 5.0.1 to work on HP- UX, I have to build it as a built-in module. That's why I have to build Python myself (and unfortunately there's no Python 2.6.2 binary distribution for HP-UX itanium available). Everything works fine except multi-threading. Before running configure and make, I set up the environment like this: export PATH=$PATH:/usr/local/bin export CPPFLAGS=-I/opt/openssl/0.9.8/include export LDFLAGS="-L/usr/lib/hpux32 -L/usr/local/lib/hpux32 -L/opt/ openssl/0.9.8/lib" I have the files generated by configure and make available, but it's too much to post it all, as as I don't know what is relevant and what not. So, here's just the first few lines of the config.log output: This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by python configure 2.6, which was generated by GNU Autoconf 2.61.
