Camera bug in CyanogenMod 12.1 sources - Android Q&A, Help & Troubleshooting

Hello everyone!
I try to compile CyanogenMod 12.1 on my Samsung Galaxy Note 10.1. But when I compile the code i get an error:
PHP:
In file included from frameworks/av/services/camera/libcameraservice/CameraService.h:26:0,
from frameworks/av/services/camera/libcameraservice/CameraDeviceFactory.cpp:21:
hardware/libhardware/include/hardware/camera.h:65:9: error: 'camera_frame_metadata_t' has not been declared

What is it? The 'camera_frame_metadata_t' definition can be found in system/core/include/system/camera.h:
PHP:
typedef struct camera_frame_metadata {
/**
* The number of detected faces in the frame.
*/
int32_t number_of_faces;
/**
* An array of the detected faces. The length is number_of_faces.
*/
camera_face_t *faces;
} camera_frame_metadata_t;
So, how to solve this problem? Hope for your help.

Nobody knows?

The problem has been solved. I just moved the structure 'camera_frame_metadata' a little higher after 'camera_face'.

No, the problen has not been solved. I still get the error.
Please help.
