C6657导入或者创建工程编译提示unsolved symbol CSL_xxxx



你好,我想实现一个C6657的中断方式核间通信,导入一个6678的例程,想改写成6657的,导入后加了include文件目录,程序本身没有错误,但是编译就是提示有

Description Resource Path Location Type unresolved symbol CSL_chipReadReg, first referenced in ./main.obj IPC C/C++ Problem

Description Resource Path Location Typeunresolved symbol CSL_CPINTC_open, first referenced in ./Interrupt.obj IPC C/C++ Problem

等等的是个错误,试了好多方法,都没解决,请问如何解决啊?另外include目录下会有符号表示,比如${CG_TOOL_ROOT}请问这些变量代表的含义。

谢谢!
