[acs] EPICS 3.15.6 on RHEL9

[Gary Croke]

Hi All,

When I got iocsoftinj3 running 3.15.6 on RHEL9 (opsbat9), it entered a continual reboot cycle.  This seems to be related to the system database 7.1.  Sue has reported having the same problem.  The ioc runs fine without system.  As a test I also built 7.0 against 3.15 on RHEL9, and the ioc runs fine with this version.  Does anyone know what causes this?

I also attempted to use epics 3.15.9 as Brian suggested.  I had to build a bunch of stuff.  The outcome is the same, fine with system 7.0, crashes with 7.1

Gary

Thanks Brian,

I had been building on my local machine, which is 9.1.  I rebuilt, relinked and restarted, and now it's booting, but immediately crashing, which is progress I guess!  Maybe I just hadn't run makelynx or something.  I'll try 3.15.9.  Thanks again.

It looks like the 64bit version didn't get installed:

-rwxrwxr-x. 1 gcroke epics 9835008 May 23 13:41 O.rhel-9-x86_64/iocsoftinj3Apps*

Gary,

Where are you doing the build? /usr/lib64/libstdc++.so.6 is a standard system library and should be in place on all rhel9 machines. It's definitely there on opsbat9.

BTW, R3.15.6 would not fully build on rhel9. There's probably enough there to build your soft ioc app, but if you run into missing EPICS libraries you might need to upgrade to R3.15.9, which shouldn't be a big change.

Hi Folks,

Trying to port iocsoftinj3 to opsbat9, get the following:

./iocsoftinj3AppsO/iocsoftinj3Apps: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

Is this just a case of copying files?  Seems we don't have an operational soft ioc with this combo of 3.15.6 and RHEL9 yet.

Thanks,

Gary
