DSTAR2YSF compiling error

[Seong-Hwan]

I have a raspberry pi 3B and pi version is
pi@raspberrypi:~/MMDVM_CM/DSTAR2YSF $ uname -a
Linux raspberrypi 5.10.103-v8+ #1530 SMP PREEMPT Tue Mar 8 13:06:35 GMT 2022 aarch64 GNU/Linux

DSTAR2YSF compiling error happens as follows;

pi@raspberrypi:~/MMDVM_CM/DSTAR2YSF $ sudo make
g++ -g -O3 -Wall -std=c++0x -pthread -c -o Conf.o Conf.cpp
g++ -g -O3 -Wall -std=c++0x -pthread -c -o CRC.o CRC.cpp

g++ -g -O3 -Wall -std=c++0x -pthread -c -o Log.o Log.cpp
g++ -g -O3 -Wall -std=c++0x -pthread -c -o ModeConv.o ModeConv.cpp

28 | #include <md380_vocoder.h>
| ^~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:16: ModeConv.o] Error 1

How can I overcome this error?
