如何在詹金斯中使用 GoogleMock？

Question

我在 CentOS 虚拟机上安装了 Jenkins。现在我想用模拟（谷歌模拟）运行单元测试（谷歌测试）。我尝试安装here 中描述的框架。 （在我的 lubuntu 机器上，使用这些步骤可以正常运行）

当我尝试构建时：

g++ -O2 -pthread -Werror -Wall -o unitTest DriveTest.cpp Drive.cpp PWM.cpp -lgtest -lgtest_main -lgmock

我收到以下错误：

 make unitTest
 g++ -O2 -std=c++0x -pthread -Werror -Wall -o unitTest DriveTest.cpp Drive.cpp PWM.cpp -lgtest -lgtest_main -lgmock

我该如何解决这个问题？

Answer 1

您在 CentOS 上的 GCC 版本似乎太旧，无法处理这些可变参数模板。我希望 4.4.7 可以使用它们，因为 the status page 似乎表明它们应该可用。不过this question 似乎证实了这种情况。

我的建议是使用dev-toolset 2 repo 升级编译器。这将使您可以访问 CentOS 6 上的 GCC 4.8（我猜您正在使用的是 GCC 版本），但使用经过修改的 stdlib，这意味着您的二进制文件仍将使用 CentOS/RedHat 5 的运行时运行。
