我正在尝试为iOS构建Allegro 5.0.8游戏库，看起来CMake 2.8.10.2在Xcode 4.6中失败了：
localhost:build steve$ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-iphone.cmake -G Xcode ..
-- The C compiler identification is Clang 4.2.0
-- The CXX compiler identification is Clang 4.2.0
-- Check for working C compiler using: Xcode
-- Check for working C compiler using: Xcode -- broken
CMake Error at /usr/local/Cellar/cmake/2.8.10.2/share/cmake/Modules/CMakeTestCCompiler.cmake:61 (message):
The C compiler
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"
is not able to compile a simple test program.
It fails with the following output:

有什么想法吗？
