How to build Python 2.6.2 on HP-UX Itanium with thread support? Note: I know that the first address to post this question is comp.lang.python, but I posted this question a week ago on comp.lang.python (http://groups.google.com/group/comp.lang.python/browse_thread/thread/c7006ad...) and unfortunately, I didn't receive any answers.
According to Patch 1225212, at least Peter Kropf was able to get Python running with threading support on this platform, though AFAIK he was not using GCC.
But I guess it should be possible with GCC as well.
Is anyone able to confirm that Python (built with GCC) does or does not work with multi-threading on HP-UX Itanium?
The good news: I did get Python 2.4.x working on HP-UX Itanium, with threading. The compiler was gcc 4.0.x. (I also tried building Python with aCC, but failed.) I remember building both 32-bit and 64-bit versions. I don't remember it being that hard. Used the source for the package at hpux.connect.org.uk as a starting point, since it had a lot of good porting tweaks, but it needed some further tweaking. (The main one I remember that is that the shared library extension for Itanium should be .so not .sl There were also a bunch of paths that required appending 32 or 64.) We used that build of Python in production, for very heavily multithreaded code, on multi-CPU boxes. Worked fine. AFAIK they're still using it. I'm not sure why the binary available at hpux.connect.org.uk has threading disabled. I suspect that some older version of HP/UX had pthread bugs that got fixed somewhere along the line. The bad news: I did this about 3.5 years ago, and I don't work there anymore, so I don't have access to that HP-UX hardware anymore, or to the notes I made when I was doing the port. So I can give you encouragement but not step-by-step instructions. Sorry. -- David Ripton dripton@ripton.net
