xcode4 - 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

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

我发现我可以使用 llvm make 命令来构建

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

OK (293 tests, 293 ran, 791 checks, 0 ignored, 0 filtered out, 7 ms)

2) 然后我 cd 到示例目录。我收到以下错误。我试图调查但找不到解决方法。您的帮助将不胜感激。

Answer 1

我能够在运行 Lion 的 Mac 上找到 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 位变体链接到/usr/local/lib 之后，我能够顺利地创建 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
