CppUTest示例构建失败

Question

我是Mac新手！ 我下载了xcode4.2并尝试构建CppUTest-v3

1）当我做的时候，我有以下日志

Linking CppUTest_tests

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

我发现可以使用llvm make命令进行构建

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

2）然后我进入示例目录。 我收到以下错误。 我试图进行调查，但找不到解决方法。 您的帮助将不胜感激。

Answer 1

我可以在运行Lion的Mac上找到CppUTest缺少的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，因此将64位变体链接到/ usr / local / lib后，我可以轻松地制作CppUTest。

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
