2to3 and version numbers with distribute
by Andrew McNabb 08 Feb '12

08 Feb '12

I'm trying to use 2to3 in setup.py for the first time. I have distribute installed, so it sounds like I should be able to just add "use_2to3=True" to my call to setup, and things should just work. Unfortunately, the setup.py is currently importing the package in order to determine the version number. Specifically, setup.py has: from xyz import version setup(name='xyz', version=version.VERSION, ...) If I run "python3 setup.py build", this fails because the "from xyz import version" causes lots of python3-incompatible code to get called. It seems like there's probably an easy way around this that I'm missing. In theory, I could specify the version number in two different places and hope that they would stay synced, but I'm not smart enough to pull that off. :) Is there anything else I should try?

[RFC] real cross-compiling support for Distutils2
by Yegor Yefremov 06 Feb '12

06 Feb '12

What is the state of real cross-compiling support in Distutils2? AFAIK cross-compiling is supported only for various Windows compilers Visual Studio, MinGW, Borland etc. What I need is an option to cross-compile software for other architecture like: host - x86, target - ARM. I encountered following problems trying to cross-compile netifaces 6.0 for ARM Linux: 1. the cross-compiler was not used for all compilation stages without following package: http://pypi.python.org/pypi/distutilscross 2. during header search process temp c files were created, compiled and executed. Execution led to an error (cross-compiled binary). What is the proper way of searching for required headers/libs aka autoconf? 3. Libraries search paths (LDFLAGS) were ignored at linking stage Version 7.0 fixes problems 2 to 3, but the first one still remains. Projects/distros that are using cross-compilation are: Yocto (http://www.yoctoproject.org/) Buildroot (http://buildroot.uclibc.org/) many others Regards, Yegor

where should one download distutils2 from?
by Bill Janssen 05 Feb '12

05 Feb '12

I just tried to download distutils2 from PyPI (1.0a3) for my OS X 10.5.8 system (that's Python 2.5). Errors out trying to run setup.py: % python setup.py build ... running build_scripts creating build/scripts-2.5 error: file 'distutils2/mkpkg.py' does not exist % This seems an unhappy state of affairs. So, where should I download a real copy from, and why isn't the package on PyPI up-to-date? Bill

trouble determining source for gcc command arguments
by Robert Altman 05 Feb '12

05 Feb '12

I have two mac os/x computers, each up to date with the same compiler and environments, yet it appears that distutils is emitting different gcc arguments. Specifically, one of the computers is attempting to compile Mercurial using the -isysoot ... argument, effectively causing the build process to fail. Details: os/x 10.7 Python 2.7.2 (installed from 10.7 installer at python.org) Mercurial source is 2.1 I don't see any environment settings which would cause gcc to use to -isysroot argument and I cannot determine where else it might be coming from (it is not in the Mercurial project), so I believe it must be coming from distutils. Thanks! Robert

getting the local site_packages
by Andrea Crotti 03 Feb '12

03 Feb '12

With something like this site_packages = pkg_resources.get_python_lib() I get the python global path of the site-packages directory, is there a way to get also the local one, which for example on Linux might be something like $HOME/.local/lib/site-packages ? Thanks, Andrea
