I installed XEphem without much trouble just now on brand new hardware using Linux Mint O.S. ver. 20.1:

0) Unziped the file from and as instructed by the INSTALL file:
cd GUI/xephem

1) Downloaded and expanded the MOTIF libraries into my /usr/lib directory as a new directory /usr/lib/linux-x86-motif-dev

2) Following the recommendation on , inserted this line into Makefile above the "ifdef MOTIF" line:
MOTIF = /usr/lib/linux-x86-motif-dev
(because that's where I parked the file referred to in the step above)

3) Made Alexander Wessel's edits to Makefile, as he recommended in his 8 March 2021 e-mail:
XLIBS = -lXm -lXt -lXext -lXmu -lX11
CFLAGS := $(LIBINC) $(CFLAGS)
LIBS = $(LIBLNK) $(XLIBS) $(LIBLIB) -lm

4) As instructed by the INSTALL file:
make MOTIF=../../libXm/linux86

5) Only one wrinkle: my /usr/bin/ld could not find -lXext and -lXmu so I just deleted those two items from the XLIBS specification and ran the "make" again. (Am I right to understand that these libraries pertain to printing?)

6) Continued with Steps 2, 3, ..., n in the INSTALL instructions.

Thanks for everybody's help,
Bernie
