synergy 无法编译——未定义的对 `pthread_xxxx 的引用答案

【问题标题】：synergy won't compile -- undefined reference to `pthread_xxxxsynergy 无法编译——未定义的对 `pthread_xxxx 的引用

【问题描述】：

关注build instructions for Synergy 时，出现以下错误。

是否有已经开发的解决方案来构建 Synergy？
如果没有，我如何让 Synergy 在 Ubuntu 13.10 上编译？

【问题讨论】：

在 Ubuntu 存储库中没有协同作用吗？你为什么要自己编译而不是从 repos 安装它？
虽然 Synergy 在 repos 中可用，但我希望为项目的改进做出贡献。在我这样做之前，我需要能够编译它。我希望在这件事上得到帮助。

【解决方案1】：

解决方案：手动将/synergy-1.4.15-Source/src/cmd/synergyd/CMakeFiles/synergyd.dir/link.txt的内容顺序更改为@987654321 @。

【解决方案2】：

您宁愿编辑CMakelists.txt 文件以在@987654323@ 命令的末尾添加pthread。

您也可以添加link_libraries(pthread)。
