Xcode4 CppUTest示例生成失败

我是麦克的新手！ 我下载了xcode4.2并尝试构建CppUTest-v3

1） 当我制作时，我有以下日志

ld: library not found for -lgcov
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我发现我可以使用llvmmake命令进行构建

CC=/Applications/Xcode.app/Contents/Developer/usr/bin/llvm-gcc-4.2 make

2） 然后我将cd刻录到示例目录。我犯了以下错误。我试图调查，但找不到解决办法。谢谢你的帮助

我在我的Mac running Lion上找到了CppUTest丢失的libgcov.a的位置

/usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin11/4.2.1/libgcov.a
/usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin11/4.2.1/x86_64/libgcov.a

显然，这些位置不在加载程序的默认搜索路径中，因此在将64位变量链接到/usr/local/lib之后，我能够进行CppUTest，而不会出现问题

sudo ln -s /usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin11/4.2.1/x86_64/libgcov.a /usr/local/lib/libgcov.a

祝你好运
