Hi Han, et. al.,

I have been able to build and use medm on Ubuntu 18.04.
I needed to install these dependencies, and I have LibXt.a in /usr/lib/x86_64-linux-gnu:
	build-essential
	libmotif-dev
	libxmu-dev

I have also (unsuccessfully) attempted to build it on Scientific Linux 7 by adding these dependencies:
	openmotif
	libXmu
	libXt
	libXm.so.4
I end up with build fail because libXt.a is unavailable, but I do have libXt.so in /usr/lib64.

Hope this helps,

Peter.

There are few more interesting cases which I've found so far :

1) EPICS Base version
2) Linux Distribution (Debian, CentOS)

The following README may help your case.

HTH,
