[CMake] CMake 2.8.8 : Reproducible Crash in Mac OS X 10.8

[David Cole]

Yes, it's true, but now there's extra required beyond simply "installing Xcode".

Brad's partially addressed the problem here today, with this commit,
now in 'next':

  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=e88bae77c3388a5b474b081e572004f02772d162

However, in order to run on one of these new systems, and get a good
command line build going, you probably have to do something like:

  xcrun bash
  cmake in the "Xcode environment"
  Ctrl+D to go back to the non-Xcode env

So..... just like all the other makefile generators, you have a sane
"build env" at CMake configure time.

Using xcode-select should get us part way there, but now that we have
this new world of command line tools separate from "installing Xcode",
we do have to adapt to it somehow.

Having these emails in the mailing list archive is at least a start to
get people thinking in the right direction.


Cheers,
David


P.S. -- thanks for chiming in and being a little pedantic... good word
for a Friday :-)

With 10.8 it would seem that installing "Xcode" is not enough to get the command line tools any more. The developer now needs to know to also install the "Command Line Tools" in addition (or in leau of*) Xcode.

Beyond that we are getting to the point that Windows is at where one is expected to have a fully functioning Visual Studio Command Prompt for CMake to generate Visual Studio Projects. A pain yes, but a fact of life.

That said we will try to make cmake print a helpful message or work out of the box.  I am just wondering how other projects are handling the sudden disappearance of the compiler from the command line...  (it has been there since the very first OSX Mac...)
