The original answer that I wrote almost 2 years ago is now outdated; here is how to do it today.
我大约两年前写的原始答案现在已经过时了；这是今天的方法。
Either right click on the project folder or File > Properties, then C/C++ Build > Settings. At the GCC C++ Linker > Linker flagsadd -pthreadand finally hit the Applybutton. That's all.
右键单击项目文件夹或File > Properties，然后C/C++ Build > Settings。在GCC C++ Linker > Linker flags添加-pthread并最后点击Apply按钮。就这样。
I have tested this with gcc 4.8 and Eclipse Luna on Ubuntu 14.04. Thank to Neil Traft for pointing it out in a comment.
我已经在 Ubuntu 14.04 上使用 gcc 4.8 和 Eclipse Luna 对此进行了测试。感谢 Neil Traf 在评论中指出。
The original answer from February 2014, now outdated:
2014 年 2 月的原始答案现已过时：
Either right click on the project folder or File > Properties, then C/C++ Build > Settings.
右键单击项目文件夹或File > Properties，然后C/C++ Build > Settings。
At the GCC C++ Compiler > Miscellaneousadd -pthreadto Other flagsand hit the Applybutton.
在GCC C++ Compiler > Miscellaneous添加-pthread到其他标志并点击应用按钮。
At the GCC C++ Linker > Librariesclick the icon with the green plus sign on the Librariesbar to add pthreadand finally hit the Applybutton.
在GCC C++ Linker > Libraries单击Libraries栏上带有绿色加号的图标进行添加pthread，最后点击Apply按钮。
This must solve it.
这必须解决它。
Note that you have to tell both the compiler and the linker that you are compiling a multi-threaded application (passing -pthreadto the compiler and -lpthreadto the linker).
请注意，您必须告诉编译器和链接器您正在编译多线程应用程序（传递-pthread给编译器和-lpthread链接器）。
