Re: MEDM crash

["Siddons, David via Tech-talk" <tech-talk at aps.anl.gov>]

that is exactly what I did. I took out all references to libXp in the medm Makefiles and removed the dependency on PrintUtils in the main Makefile (attached).

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-ub18

 

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.

As Bob pointed out you have an empty include path in your build. The last -I option there was eating up the -MM which explains the error message, so one of your extensions config variables was probably empty.
