[Bf-committers] cmake Xcode question

[jonathan ferguson]

hi.

Are you sure that the build system is looking at the 10.4u SDK?   
While you will have a Python.h in the 10.4u SDK, you will also have  
one in the canonical user location of
/System/Library/Frameworks/Python.framework/Headers/Python.h.

I may be stating the obvious, but the 10.4u SDK is primarily used  
when you've got a cross compiling situation, and need or want to  
build Universal Binaries. Blender does not ship universal binaries  
due to bandwidth concerns--- afaik.

As you may recall, on Mac OS X you want to use the 2.3 Python  
Framework unless you have a REALLY good reason not to--- see my post  
of a month back:
http://projects.blender.org/pipermail/bf-committers/2006-November/ 
016168.html

 From my elementary understanding, CMake creates the XCode project  
files, yes? If so, I would ask questions of the CMake developers /  
users regarding not having the "zero linking" working (aka,  
background compiling). Perhaps they're missing something in the XCode  
project file they're generating?

Now "attacking the darkness with magic missile," external build  
systems when used in Xcode are not privy to things like zero link---  
only the XCode build system does that. So, if the XCode file  
generated by CMake actually *uses* CMake as the builder, then you  
will not get zero link and some other handy bits.

The variables set in XCode may or may not reflect what's going on,  
given that CMake produces the XCode project file, and given that  
XCode has a host of default values you may need to change--- when  
converting an older version of XCode project to a new version of  
XCode. Again, an external build system is external, and XCode has no  
special knowledge of that system in general.

I hope that helps.

have a nice day.yad
