There is a trial to improve the situation:

That fixed it.  I should have noticed that the Makefile has a commented out line to do that.  This is the "git diff" that fixes the problem.

  #Xp is not available and not needed on Linux Mint 18

Mark,

Try to compile without Xp. makefile should contains

USR_LIBS_Linux = Xm Xt Xmu X11 Xext

instead of

USR_LIBS_Linux = Xm Xt Xp Xmu X11 Xext

IIRC there are some libraries that are no longer needed and that might be one of them, try modifying the Makefile to take that out and see whether it builds.

I solved that.  I was missing this file that needs to define X11_LIB and MOTIF_LIB:

extensions/configure/os/CONFIG_SITE.linux-x86_64-ub18.linux-x86_64-ub1
8

However, now I get this error:

    -lANLwidgets -lPrintUtils -lca -lCom -lXm -lXt -lXp -lXmu -lX11 -lXext   -lpthread   -lreadline -lm -lrt -ldl -lgcc
/usr/bin/ld: cannot find -lXp
collect2: error: ld returned 1 exit status
/corvette/usr/local/epics/base/configure/RULES_BUILD:212: recipe for
target 'medm' failed

I have Googled to see what package provides libXp.so on Ubuntu 18, and I can’t find it.  Others have the same problem.

Pete and Bob how did you install libXp.so?

That PR builds OK on Centos 7, but it fails to build on Ubuntu 18.  I see the same failure on Ubuntu 18 with the MEDM_3_1_14 tag.
