c++ - Gtest 无法在 mac 上使用默认编译器进行链接

Question

当我尝试构建一些使用 GTest 的代码时，在我的 mac 上使用最新的 clang，它无法链接到

Undefined symbols for architecture x86_64:
  "testing::Message::Message()", referenced from:
      parse::testing::DiffWithGoldenFile(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&) in v8test_helper.o

...

有人对修复它有想法吗？

通过使用标志编译 Gtest 解决了这个问题

./configure CXX="clang++ -std=c++11 -stdlib=libc++" && make
