Question

我正在尝试在Rehat 7系统上构建并安装google-cloud-cpp。我正在使用https://github.com/googleapis/google-cloud-cpp-common/blob/master/INSTALL.md上的说明使用cmake安装选项。

我已经安装了所有先决条件。

根据指示，最后2个步骤是：

cmake -H。 -Bcmake-out cmake --build cmake-out --target安装

当我运行第二个命令命令时，出现链接错误，该错误似乎来自Google测试：

此库已安装。

有人可以帮我吗？

感谢您提供任何信息，

google-cloud-cpp / doc / setup-cmake-environment.md中似乎存在一种设置机制，该机制不同于INSTALL.md中的指示。该文件中的说明描述了如何设置工作站以使用CMake构建Google Cloud C ++客户端库，这就是我正在尝试的方法。使用这些说明可以使构建质量更好。
