谷歌测试在 Eclipse 中是否支持 c++11？答案

【问题标题】：Does google test support c++11 at eclipse?谷歌测试在 Eclipse 中是否支持 c++11？
【发布时间】：2015-05-11 10:36:14
【问题描述】：

我正在使用xubuntu 14.4、eclipse luna、google test1.7。

当我通过c++11 使用谷歌测试时，它不起作用。

在我使用xubuntu 12.4 之前，它有效。

gcc 版本为：gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2。

google test 不支持c++11？

有错误信息：

我的代码是：

#include "gtest/gtest.h"

TEST(Ex,test)
{
    std::cout<<"hello googletest"<<std::endl;

}

int main(int argc, char * argv[])
{
    ::testing::InitGoogleTest(&argc, argv);
    RUN_ALL_TESTS();
    return 0;
}

【问题讨论】：

你的构建编译选项命令行是什么？
将错误信息缩进4个空格并添加标签，使其看起来更有吸引力。还从代码中删除了额外的缩进。

标签： eclipse unit-testing c++11 gcc googletest

【解决方案1】：

简短的回答是肯定的，googletest 确实支持 C++11，尽管你所说的“支持”不是很清楚。如果这就是您的意思，您绝对可以使用实现 C++11 标准的编译器来编译 googletest。

关于错误，您在链接时似乎缺少 pthread 库。我不确定如何在 eclipse 中执行此操作，但一般情况下，您需要在编译时将“-pthread”传递给 GCC。
