[Pythonmac-SIG] Anyone tried to build python or extensions with XCode 4.0?

[Mark Livingstone]

Ok, what you say is true for the release version of XCode 4.

However, I have just installed XCode 4.0.1. When it installed, it
moved my existing XCode 3..26 into the /Developer.old folder. I went
in there, ran XCode 3 and with no changes was able to compile a 10.5
SDK version of the CUDA test application.

I think Apple has just decided to draw a line in the sand with XCode
4. They are still supporting XCode3 as can be seen by the 3.2.6
release after the release of 4.0.0. I am writing this msg on an Intel
Mac Pro which I bought within days of their release so I don't doubt
there are G5s still doing Sterling service, but we all know that Apple
is not afraid to say "Time to move on". It is not Apple who is begging
their customers to stop using IE6!!

I can't wait to see what innovative software XCode 4 will inspire us to write.
