[Pythonmac-SIG] Link against Python Framework
Hi, In my Cocoa app, I link agains the Python framework to be able to call "PyRun_SimpleString" and load bundles based on python. If I set the Base SDK to 10.5, it runs on 10.5 and 10.6. But if I set it to 10.6 and MACOSX_DEPLOYMENT_TARGET = 10.5 it complains in Leopard that it can’t find python 2.6. Is there a my to always use the current python version (2.5 on Leopard and 2.6 on Snow Leopard) I link against the "/System/Library/Frameworks/Python.framework" Regards Georg ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Major Python releases (such as 2.5 and 2.6) are not necessarily binary compatibel. If you are careful you can get a single binary that works with 2.5 and 2.6, but you then have to load the framework manually and also manually resolve any python API functions you are using. The easiest way to do that is using the CFBundle APIs in CoreFoundation. It might be easier to create two plugin bundles for your application: one that links against 2.6 and one that links against 2.5. You can then load the plugin that is most appropriate for the currently running OS version.

[Pythonmac-SIG] Compiling libhid with python support : configure can't link to test program
Hello everyone, I would like to compile libhid (because I couldn't find it already compiled) on mac os x 10.5.x. When I run configure it dies saying it can't link against my python lib and that it may be installed in an alternative location or that I need to install a dev version of python. I'm using the version shipped with 10.5, does anyone know how to fix this?

I've always wondered about this. That could in theory break applications. Luckily Apple is very reluctant about breaking applications and hence ships multiple versions of Python (/System/Library/Frameworks/Python.framework on 3 versions of python: 2.3, 2.5 and 2.6). This means that you can safely link to the system Python on a 10.5 system (or even a 10.3.9 system) and run your application on a 10.6 system.

I've always wondered about this. In theory, it is possible. But Apple takes care to maintain backwards compatibility. If you poke around in /System/Library/Frameworks/ Python.framework/Versions, you'll see that (on Snow Leopard) they ship 2.6, 2.5, *and* 2.3 (2.3 shipped with Tiger). So the version of Python to which your app links should be available going forward. If you want to make absolutely sure that Apple can't break you, you could bundle the version of Python.framework upon which you depend into your app. However, that's probably not necessary unless you want to use a newer version of Python than the system has (say, 3.0+, or 2.6 on Leopard).

Hey actually whats my requirement is i need to gather information from SAP system and Store it in Python appliction server. For this i am thinking to construct a web service on python in order to get the data from SAP system. Is this the correct way or is there any other possibility get in formation and store it in python application and i use mysql database for python. Please give your valuable suggestion.
