Re: Building modbus 3-4 on rhel-9 epics 3.15.9

[Sue Witherspoon via Tech-talk <tech-talk@aps.anl.gov>]

Many thanks to Mark Rivers and Andrew Johnson! That pointed me in the right direction! 

I removed the reference to Linux in the configure/CONFIG_SITE file and let the default figure it out.  

    ie: 

           #CROSS_COMPILER_TARGET_ARCHS =

The real problem was in the order of libraries in the application's src/Makefile. I needed to put

asyn after  modbus.  Then all compiled and loaded and is now running! 

As always, this epics community is SUPERB!! 

Thanks again!!

Hi Sue,

 

I think the problem is this part of each g++ command:

-I/usr/dvlepics/epics/R3.15.9.J0/include/os/

 

That should actually say

-I/usr/dvlepics/epics/R3.15.9.J0/include/os/Linux

 

I suspect perhaps you don’t have EPICS_HOST_ARCH defined correctly?

 

Mark

Apologies in advance for what I think is an old issue, but I seem to be missing something.

I am trying to make modbus-R3-4 on a rhel-9 server. I got the src from the github.com/epics-modules/modbus/tree/R3-4

Is there a particular FLAG and define that will mitigate this problem with osdTime, osdSock, osdEvent  etc. ?

-Thanks in advance
