Hi3516DV300芯片报错“ undefined reference to ×”

我在使用海思硬件接口的时候，用到了mpi库，然后Makefile里面链接了这个库，但是编译到了链接的时候报错了：

这些信号相关的函数链接pthread库，HI_*相关的接口去文档查属于哪个库，或许我的文档跟当前开发板不匹配，我连续找了三个没找到，不过这么火的芯片别人肯定也用过，所以方案一直接上网搜该函数；方案二我有一份领导给的头文件和库文件，我到整个头文件里面能找到相应的函数，然后就去把名字差不多的库文件链接进去，果然编译通过了。还有要特别注意的是基础库要靠右侧。最后，strncpy_s等几个函数海思有自己的实现，在库libsecurec.so（或静态库libsecurec.a）里面，这个基础库要靠右侧放。

附上自己的Makefile吧，省得下次忘记了
