Re: SynApps compilation error

[Lucas Russo via Tech-talk <tech-talk at aps.anl.gov>]

Hello Marco,

Commenting on the second solution.

I would say that even though you created symlinks from /usr/include/rpc 

pointing to /usr/include/tirpc/rpc (that solves the header issues) you still 

need asyn to be linked against tirpc.

Looking at asyn R4-36 files I think you should set

configure/CONFIG_SITE:

TIRPC=YES 

So that would enable asyn to be linked against tirpc and solve your undefined reference issue.

asyn/Makefile:

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

Hope this helps,

Lucas

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?

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.
