Unstubbed Entities Log

--------------------------------------------------------------------------------

*** This is not an error log ***

The existence of entities in this log does not signify that an error has

occurred. The purpose of this log is to provide a reason to you when a

symbol has not been stubbed by VectorCAST. When a link error occurs, the

'Reason Not Stubbed' column provides an explanation. In certain cases you

may be required to provide a definition for certain entities in user code.

Please consult the User's Guide for more information.

GDFLIB_FilterMAInit_FLT function Entities from non-Search directories are expected to be defined in an external library. If this entity is missing from the harness, specify the appropriate library in the linker options. If you want this entity to be stubbed instead, either specify the directory as a Search directory or add this item to Additional Stubs. However, standard library items should usually not be stubbed.

7.出现这种情况的报错一般就是编译器库函数封装不严格，尝试添加stub，首先添加GDFLIB_FilterMAInit_FLT和GDFLIB_FilterMA，暂时不考虑添加memcpy和memset（因为这两个函数来源于库函数，排查优先级较低）。添加成功后点击更新按钮

memcpy指的是C和C++使用的内存拷贝函数，函数原型为void *memcpy(void *destin, void *source, unsigned n)；函数的功能是从源内存地址的起始位置开始拷贝若干个字节到目标内存地址中，即从源source中拷贝n个字节到目标destin中。
memset是计算机中C/C++语言初始化函数。作用是将某一块内存中的内容全部设置为指定的值，这个函数通常为新申请的内存做初始化工作。
GDFLIB_FilterMAInit_FLT常规数字滤波器库，故障定位测试初始化过滤。
GDFLIB_FilterMA常规数字滤波器库，主报警信号过滤。
