Re: [Python-Dev] Python 2.7 Won't Build
Continuing on with investigating Python 2.7 build problems, one problem I just discovered is a different installation on one 64-bit system (Debian Lenny) versus another (Ubuntu 10.04.1 LTS). I used gcc-4.5.1 on both systems, with no *PY* environment variables set. On Debian I got two directories: /usr/local/lib64/python2.7 /usr/local/lib/python2.7 and only the first had the config subdirectory. On Ubuntu I got only /usr/local/lib/python2.7 I see that the configure file has some architecture choices (--with-universal-archs=ARCH) but no explanation about the consequences. Can anyone explain the two different default installations I got? It seems to me I should force the Ubuntu-style installation by the --with-universal-archs=64-bit configure option, and I will try that on Debian while I await expert help. Thanks. -Tom ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

On Ubuntu I got only
/usr/local/lib/python2.7
Okay, that leads to an install problem with bazaar on the Debian beast:
Could not find platform dependent libraries exec_prefix
Consider setting $PYTHONHOME to prefix[:exec_prefix]

raise IOError(msg)
IOError: invalid Python installation: unable to open
/usr/local/lib/python2.7/config/Makefile (No such file or directory)
I tried setting PYTHONHOME to various things but none worked. The
problem is that the config directory is under /usr/local/lib64 and
none of the documents I have found describes how to handle that
situation. All the environment variables seem to be for libraries,
modules, and executables, and there is no reference to any lib64.
The pkg-config program looks as if it could be used by such packages
as bazaar but it doesn't look like it's one of the usual installation
tricks.
I'll go to the bazaar mailing list while awaiting an answer here.
Thanks,
-Tom

The more I look into it, though, it seems to be a legitimate developer question. The python installation scripts know how to install on a mixed 32/64 bit system but missed fixing it to look like a more universal system (if that's the proper word) for programs wanting to read its installation configuration.

I think universal arch builds only apply under OS X where they
produce fat binaries.
Under 64-bit Linux, you can compile either a 64-bit executable (the
default) or a 32-bit executable (by specifying e.g. CC=gcc -m32 to
the configure script).
However, the /usr/local/lib{,64}/python2.7 issue is a bit different,
since those directories can host architecture independent files
(such as .py and .pyc files). For example, on my Mandriva
install, the 64-bit Python executable can import packages from
both /usr/lib/python2.6/site-packages/
and /usr/lib64/python2.6/site-packages/.
Thanks, Antoine.
And I think I just found the problem with the installation (it may be
worth a note): I had a special configuration file
(/usr/local/share/config.site) for autoconf to force the primary local
libraries to be installed in /usr/local/lib64 (left over from early
64-bit days of this old system). Removing that file, removing the
/usr/local/lib64/python2.7 directory, and rebuilding and reinstalling
seems to have solved the immediate problem.
Moral of the story: watch out for old cruft in /usr/local when
installing a new distribution.
I apologize for the noise.
However, I'm still investigating the original build problem (gcc trunk
and corrupted byte compile), but it may be related--I'll see.

[Python-Dev] Python 2.7 Won't Build
I am trying to rebujild the 2.7 maintenance branch and get this error on Ubuntu 10.04.1 LTS: XXX lineno: 743, opcode: 0 Traceback (most recent call last): File /usr/local/src/python-2.7-maint-svn/Lib/site.py, line 62, in module import os File /usr/local/src/python-2.7-maint-svn/Lib/os.py, line 743, in module def urandom(n): SystemError: unknown opcode I installed it successfully once so I may be getting conflicts, but I can't figure out why. There were some similar bugs reported in previous versions but I didn't see a clear solution. I have done make distclean and ./configure. I have unset my PYTHONPATH and LD_LIBRARY_PATH, but python2.7 is my default python. I guess my next step will be to manually remove the installed python 2.7 unless I hear some other suggestions. And I will file a bug report soon unless that is inappropriate. Thanks, -Tom Thomas M.
