building python
For some pointers on how to get python to build in 64 bit mode see http://mail.python.org/pipermail/pythonmac-sig/2007-June/019045.html To quote (which is actually about 64 bit on *Tiger*): <quote> The build is universal, but for me only one of the two archictures actually worked: I did my build on an Intel system and the 64-bit build worked on that machine, but didn't work on a G5 mac. That's probably something shallow, but as that machine doesn't have the Xcode installed and is on the other side of a slow network connection I haven't tried to debug this yet. 1) Edit the configure script, look for "-arch i386" and "-arch ppc" and change that those to "-arch ppc64" and "-arch x86_64". You'll have to make multiple changes to the configure file. 2) Build using: $ mkdir build $ cd build $ CFLAGS="-arch ppc64 -arch x86_64" ../configure \ --enable-universalsdk \ --disable-toolbox-glue --prefix=/opt/python25-64bit $ make $ make install 3) Optionally: run "make testall" to run the unittests and check pyconfig.h to check the various SIZEOF definitions. You now have a 64-bit build of python in /opt/python25-64bit.
Cython {{{ 20:58 < mabshoff> There is also a bug in the way Cython builds its extensions.
20:58 < mabshoff> It needs to use the flags python was build with, not some random stuff people thing 20:58 < mabshoff> think is good. 20:58 < mabshoff> I told Robert about it.
But:
[06:36] <mabshoff> But it doesn't match the python flags. I checked on it once. [06:37] <was_> It's distutils. [06:37] <was_> Cython doesn't have anything to do with the flags. }}}
