"undefined reference to setprocmask"是一个编译错误,意思是在链接阶段找不到setprocmask函数的定义。这个错误通常发生在使用了某个函数,但没有正确链接相应的库的情况下。根据提供的引用内容,这个错误可能与pthread库的链接有关。
解决这个问题的方法是在编译时添加相应的库。根据引用,如果出现undefined reference to 'pthread_create'和undefined reference to 'pthread_join'的错误,那么需要链接pthread库,可以通过在编译命令中添加-lpthread来实现。类似地,如果出现undefined reference to 'SetPduPowerConsumptionCnt'错误,可能需要链接相关的库。
请确保在编译命令中正确指定了需要链接的库,以解决undefined reference错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
