为什么我的 yaml 构建测试失败？yaml-cpp-0.6.0：handler_test.cpp:(.text+0x9f2)：对“testing::internal::GetWithoutMatchers()”的引用未定义

Question

当我安装天文学软件 purify 时。它需要最新版本的 yaml，例如 yaml-cpp-0.6.0 我没有遇到任何错误，标准输出如下

看起来还不错。但是当我在 Linux shell 中输入“make”时，它在构建过程结束时抛出一个错误，似乎没有通过一些测试。我需要安装单独的测试框架吗？

我太笨了，无法从错误代码中得到任何有用的信息。我需要帮助QAQ

为了向自己证明问题的根源，在第 24 行CMakeLists.txt，暂时地将“启用测试”选项更改为关闭并重试：

option(YAML_CPP_BUILD_TESTS "Enable testing" ON)

if(YAML_CPP_BUILD_TESTS) enable_testing() add_subdirectory(test) endif()

请注意，yaml-cpp 使用“谷歌测试“ A

合并以前独立的 GoogleTest 和 GoogleMock 项目

因此，要么您的路径中存在另一个版本的 Google Test，要么 yaml-cpp 项目未在其树中自动构建 Google Test 套件。因此，请确定https://github.com/jbeder/yaml-cpp/tree/master/test 并且子组件正在构建中。
