Hi Brandon,
  • Has anyone had any luck installing EPICS on CentOS 7?
Yes, I have been using EPICS on Centos 7 for many years.  I am currently using it on Centos 6, Centos 7, Centos 8 Stream, and Centos 9 Stream.
  • When I try to "caget temperature:water", it responds with "Channel connect timed out: 'temperature:water' not found.". 
  • I'm guessing this is because it isn't installed correctly. 
I think it is unlikely that the problem is with the installation.
  • Is it possible that the install is okay and there is a configuration issue preventing the caget from talking to the EPICS server?
Yes, that is more likely.  Please send the output of the following in the console window running caget:

printenv | grep EPICS

And send the output of the following at the IOC prompt on the EPICS server:

epicsPrtEnvParams

Mark

Subject: Trying to install EPICS on CentOS 7
 
Hello,

Has anyone had any luck installing EPICS on CentOS 7? Of the required packages for CentOS 8, I can install all but one (gcc-toolset-8-make) and there is no powertools for config-manager. It throws some errors but ultimately looks like it installs, but the basic tutorial does not work. When I try to "caget temperature:water", it responds with "Channel connect timed out: 'temperature:water' not found.". I'm guessing this is because it isn't installed correctly. Is it possible that the install is okay and there is a configuration issue preventing the caget from talking to the EPICS server?

Thank you,
Brandon
