[CMake] Problem with Xcode generator

Pim Schellart Sun, 17 May 2009 06:10:23 -0700

I want to use cmake with the Xcode generator in OSX.

Xcode 3.1 is installed (OSX 10.5.7) and building the project with the default makefile generator works fine. But if I add the flag -G Xcode to the cmake command I get the following error:


Temp $ cmake -G Xcode CMakeLists.txt
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- broken

CMake Error at /usr/local/share/cmake-2.6/Modules/ CMakeTestCCompiler.cmake:32 (MESSAGE): The C compiler "/usr/bin/cc" is not able to compile a simple test program.


  It fails with the following output:

   Change Dir: /Users/pim/Temp/CMakeFiles/CMakeTmp



  Run Build Command:/usr/local/bin/cmakexbuild -project

CMAKE_TRY_COMPILE.xcodeproj build -target cmTryCompileExec - configuration

The output I get if I use the default makefile generator is:

Temp $ cmake CMakeLists.txt
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works

-- Detecting CXX compiler ABI info

Does anyone know what is wrong here?

Kind regards,
