Error while compliing quectel_cv2x_SDK

Hello,
Follow the documentation when compiling acme,
The cross compiler was installed successfully,

cd ~/cv2x/acme
make

The following error appears
acme.c:32:10: fatal error: tunnel_mode.h: No such file or directory
#include <tunnel_mode.h>
compilation terminated.

Have you encountered any of the above problems?
Where can I find the header file tunnel_mode.h ?
I really hope someone can help me.

Hi, there
Please confirm the path of tunnel_mode.h
find / -name tunnel_mode.h
and check whether the path setting is correct .


If the file does not exist, please update the SDK version.

Thank you for your help !!!
The tunnel_mode.h does not exist.
