我正在尝试在Windows 8机器上使用Eclipse和ARM Sourcery Windows GCC C构建一个示例代码。当我编译代码时:我得到这个错误:
Undefined reference to symbol 'sem_post@@GLIBC_2.4
未定义的对符号“sem_post@@GLIBC_2.4”的引用。
The error doesn't say any line number or any location about the error, so I don't know which part of the code I should post. How can I get rid of this error? Thanks.
错误并没有说任何行号或错误的位置，所以我不知道应该在哪个部分上发布。我怎样才能摆脱这个错误呢?谢谢。

sem_post() lives in the pthread library, so make sure you use the -pthread flag when compiling and linking.
sem_post()生活在pthread库中，所以在编译和链接时要确保使用-pthread标记。
