制作GTest时出错

Question

我试图在我的Ubuntu机器上设置GTest环境.但在使GTest获取库时,我收到以下错误...

Answer 1

尝试在g ++命令中-lpthread转到after gtest_main.a.

Answer 2

我有同样的问题,我-lpthread在Makefile中更改为-pthread.(我放弃了小'L'.)之后编译'make'没有错误.

Answer 3

您是否看过Erik Smistad关于如何在Ubuntu上使用gtest的优秀教程？我刚刚在(K)ubuntu 12.04上尝试过,它运行得很好.简而言之,您需要做的是

sudo apt-get install cmake libgtest-dev
cd /usr/src/gtest
sudo cmake CMakeLists.txt
sudo make
sudo cp *.a /usr/lib

如果您觉得以root身份运行make和cmake会感到不舒服,则必须将/ usr/src/gtest复制到用户可写的目录中.在本教程中,Erik还提供了一个带有CMakeLists.txt的示例测试来构建它.
