I want to know how complex is the work to create a patch for any Python version. For example If i want to create a patch for Python3.1, is it a very cumbersome process? Does this work require a speacial expertise? If possible please explain me about your approach in doing this. So that i can try for myself. Thanks & regards, Anand Hi Chris,

I couldn't find any patch for Python3.1. Do you have patch for Python3.1? Thanks & Regards, Anand Hi Chris,

I just don't know the configure scripting to get the ./configure script to NOT do the "checking for %zd printf() format support" test. Any pointers there? Do you know that scripting? Once I get that done I think it will work. Thanks again. I am trying to follow the instructions from “K’s clutter loft”.

Great article. I too am looking for the 2.5.2 patch. I've poked around everywhere but couldn't find it. I tried the dholm.com address above but it's a dead link now. Any ideas? BTW: I'm cross compiling for a mips64 bit Cavium Processor. I'm pretty good (at least I think I am, as he pats himself on the back) at cross compiling. I must admit, this python stuff is a PAIN to cross compile. :) Hi Chris.

I believe that if you follow the comment above yours to dholm.com they had it working with 2.5.2. You can also look in the rej files to see what failed and try to apply the patches manually. -Chris Genar: There were some changes in 2.5.2 that make the patch not apply cleanly.

Thanks in advance I cannot cross-compile Python 2.5.2, I have execute the following commands:

Then I run the following commands:
