Error:make[1]: *** No rule to make target `Hai_Extern.obj', needed by `build/GXQ26_07B/gprs/MT6226o/lib/conn_app.lib'. Stop.
Reason:
1.在make文件中添加了 Hai_Extern.c文件的编译，但在对应的文件目录下找不到对应的.c文件。
2.在make文件中没添加生成Hai_Extern.obj目标文件的源文件.c或.h.

在生成database BPLGU文件出错原因 可能是因为缺少 以下三个文件：造成。
BPLGUInfoCustomApp_MT6226_S01_MAUI_07B_W08_16_MP_V2
BPLGUInfoCustomApp_MT6226M_S01_MAUI_07B_W08_16_MP_V2
BPLGUInfoCustomApp_MT6227_S01_MAUI_07B_W08_16_MP_V2
还有其他原因造成，则需要查build/log下log文件根据提示的错误信息来更改工程文件。

编译某个文件时提示 can not open XXX.h文件
Solve mothed:
1. 在make 文件中修改对应的XXXinc文件,添加对.h文件的编译
2. 在.h文件中包含的字符、变量、函数等，用extern 对其进行定义。
Error: L6218E: Undefined symbol Image$$ZI$$Limit (referred from sys_stackheap.o).
Not enough information to produce a SYMDEFs file.
Finished: 1 information, 36 warning and 1 error messages.
错误原因：
这个问题我们之前是有遇到过的，我记得是以为nativeInterface.c文件中以下三个函数写为空函数，即可编译通过。
void printfString(const char* message,const nano_u2* buffer,nano_s4 iLength)
void printfByteArray(const char* message,const nano_u1* buffer,nano_s4 iLength)
void printfShortArray(const char* message,const nano_u2* buffer,nano_s4 iLength)
这个问题是由于代码或者Lib中调用了 C Lib的malloc或者类似于strdup，printf 这样的会调用malloc的C Lib function 引起的。MTK Platform不支持 C lib的malloc，而用 Ctrl Buffer机制代替了malloc，以便于调试memory leak问题。

错误原因：重复包含 FunctionControl.h 文件,导致在.h文件中定义的struct 在其他文件调用时一直出错。注意：.h文件一定不能重复包含，否则编译通不过。
