[Bf-committers] mac OSX 10.10.5 and Xcode 7 cmake fix

[Levon]

Overnight my computer auto updated to OSX 10.10.5 (from 10.10.4) and to
Xcode 7.0. even though auto updates were turned off.

OSX 10.10.5 and xcode 7.0 introduce a new SDK version of 10.11 which
src/blender/CMakeLists.txt is not aware of.


Fortunately uname -r reports the system as 14.5 now.

patch to fix it.

This is problematic (not your patch, that its checking for exact OSX
versions in the first place).

This means you can't build older Blender versions on a new system,
which is needed for bisecting.
At least not easily, without manually editing the CMakeLists.txt file each step.

Did anyone look into using CMake's ability to detect the SDK on OSX?

It looks like this is supported:

- 
https://github.com/Kitware/CMake/blob/master/Modules/Platform/Darwin-Initialize.cmake#L72
- http://www.cmake.org/cmake/help/v3.3/variable/CMAKE_OSX_SYSROOT.html

Of course the patch can be applied, but would prefer if this
workaround could be avoided altogether.

I think this aggressive updating policy on Apple's part could be a real
problem for us.

uname -r on OS X 10.10.5 does give 14.5
and xcode 7 is released. I do not really get the "The patch moves
requirenment for a new CMake from 14.0 to 14.5" comment though

CMake already does this detection, LLVM AFAICS isn't hard coding the
paths with its CMake files, we can likely avoid it as well.

Yep, this goes without saying. Martijn would need to double check its
working properly before applying.

Re: [Bf-committers] mac OSX 10.10.5 and Xcode 7 cmake fix

[Sergey Sharybin]

Levon, is the OSX and new XCode officially released or they're still on the
beta state?

In any case, the patch lacks two things:

- SCons needs support of new XCode as well
- The patch moves requirenment for a new CMake from 14.0 to 14.5

Campbell, don't think we really looked into making XCode detection smarter
in CMake. It's probably possible, but to me patch is good enough (apart
form two points raised above).

I would be conservative here storngly suggest not doing more global changes
here unless it's done by someone who actually uses the platform, ready to
solve regressions and so on.
