[CMake] CMake 2.4.6 and Xcode 4.2 on Mac OS X 10.7

[Sean McBride]

Hi all,

I've updated one of my dashboard machines to 10.7 and Xcode 4.2 and am having trouble with the Xcode generator.  It fails with:

---------
The C compiler "/usr/bin/llvm-gcc" is not able to compile a simple test
  program.

  It fails with the following output:

   Change Dir: /Users/builder/external/CMake-xcode-dbg-x86_64/CMakeFiles/CMakeTmp

  

  Run Build Command:/Applications/CMake.app/Contents/bin/cmakexbuild -project
  CMAKE_TRY_COMPILE.xcodeproj build -target cmTryCompileExec -configuration
  Debug
---------

The Xcode project file at:

/Users/builder/external/CMake-xcode-dbg-x86_64/CMakeFiles/CMakeTmp/CMAKE_TRY_COMPILE.xcodeproj

is but an empty folder, and Xcode crashes trying to open it.

If I use /usr/bin/clang things work.

Anyone tried a similar setup?  How to debug this further?

Cheers,

--
