I see

I downloaded my synApps version from the first link in this table:

https://www.aps.anl.gov/BCDA/synApps/Where-to-find-it

Inside the support folder, grep -r shareLib.h reveals plenty of stuff, but grep -r shareLib.h | grep sscan reveals nothing. Inside support/sscan-R2-11-3/sscanApp/src grep -r shareLib.h also reveals nothing.

Just reporting because this information might be useful.

Best regards,

Marco

I fixed that sscan error 1.5 years ago in this commit:

https://github.com/epics-modules/sscan/commit/420274ca2e4331e92119bd0524d0bcd7ffdd9f93

Hi all

Thanks for the tips!

I dont clearly understand Makefiles syntax yet, so i might be doing some mistake, but uncommenting TIRPC = YES and adding

 # Some linux systems moved RPC related symbols to libtirpc
  # Define TIRPC in configure/CONFIG_SITE in this case
  ifeq ($(TIRPC),YES)
   USR_INCLUDES_Linux += -I/usr/include/tirpc
   asyn_SYS_LIBS_Linux += tirpc
  endif

to asyn/Makefile did not solve my problem.

A colleague of mine (Pedro Junji) noticed that saveData_writeXDR.c was missing a #include <shareLib.h> statement and this solved.

I then advanced in the compilation and got a "Xos.h: no such file or directory" error but this here worked: https://stackoverflow.com/questions/5299989/x11-xlib-h-not-found-in-ubuntu

So i guess things are evolving. Thanks again for the help.

The first solution is preferred. The error you are getting in sscan is completely separate, and may be solved in a more recent version.

Hello all.

Im trying to compile synApps in my local machine. I had the problem in which make release inside synApps_6_1/support was freezing but as Iain suggested, commenting XXX in configure/RELEASE solved it.

Im now having trouble with make rebuild. I found two strategies that take me further into the compilation process, but both end up in barriers i cannot advance. Simply trying "make rebuild" ​​right after commenting XXX in configure/RELEASE gets me:


In file included from vxi11core.h:9,

                 from vxi11core_xdr.c:6:

/usr/include/rpc/rpc.h:38:10: fatal error: rpc/types.h: No such file or directory

   38 | #include <rpc/types.h>          /* some typedefs */

      |          ^~~~~~~~~~~~~

compilation terminated.

I found two strategies, one in tech-talk and one in ask ubuntu.

1 (tech-talk solution in https://epics.anl.gov/tech-talk/2020/msg00444.php): uncomment # TIRPC=YES in asyn_version/configure/CONFIG_SITE. I append the result below.

2  (ask ubuntu solution in https://askubuntu.com/questions/1360945/fatal-error-rpc-rpc-h-no-such-file-or-directory): do "apt-get install libntirpc-dev" and create symlinks in /usr/include/rpc pointing to /usr/include/tirpc/rpc.

Anyone have any tips on how to proceed?

2 - Result of second solution:

First compiler complains about not finding netconfig.h. I then create a symlink to it in /usr/include poiting to /usr/include//usr/include/tirpc/netconfig.h.
