Hi,

I am new on Mac platform. I need to port an application from linux to mac. There are couple of custom c-extensions which I am building using cython on linux using distutils. It's pretty simple and straight forward there. There are couple of things I need to know on Mac platform.

Q1. How do I create custom c-extension (cython & distutils) on mac so that they should run on both architecture (ppc & Intel)?

If cython doesn't do anything special: just use a universal build of python to build the extension.

Q2. I am on 32 bit platform and I have to make sure that deployed package (py2app) should execute on 64-bit architecture also.

What is your question? 32-bit binaries will work just fine on system that is 64-bit capable. If you cannot test 64-bit binaries on your machine I'd only ship a 32-bit binary.

Q3. Mine is Leopard 10.5.5(intel) and default python is 2.5.1 but my app requires 2.6.6. How do I build python 2.6.6 in universal binary format?

There are two options: 1) Download the 2.6.6 installer from the python.org website 2) Built it yourself using 'configure --enable-universalsdk=/ MACOSX_DEPLOYMENT_TARGET=10.5' (replace 10.5 by the earliest OSX version you want to support) Ronald

Overall idea is to deploy a package on mac 10.5.5 leopard(intel 32 bit) using py2app in such a way so that it's compatible for both architecture (ppc & intel) and both platforms(32-bit & 64-bit)

Cheers

Prashant
