OsmocomGMR

Hello, I am trying to install OSMOCOM-GMR.
Before I started this, I have already intalled libosmocore and libosmo-dsp library.
However,I have some issues about "undefined reference to xxx".
When I make in osmo-gmr folder, there are some issue below.

----------------- Error Message --------------------
/home/xxx/osmo-gmr-master/src/gmr1_rx.c:425: undefined reference to 'gsmtap_sendmsg'
gmr1_rx.o: In function 'main':
/home/xxx/osmo-gmr-master/src/gmr1_rx.c:951: undefined reference to 'gsmtap_source_init'

/home/xxx/osmo-gmr-master/src/bcch.c:951: undefined reference to 'osmo_conv_decode'

These message are not everything. there is more.
How can I fix this issues?
Also, I use Ubuntu 16.04.7 LTS.
Thank you in advance.
