1. You need /lib, /include, and /bin.
   1. 1) Keep everything in the epics/ folder, but copy the folder over, then update $LD_LIBRARY_PATH(lib), $PATH(bin),  $CPATH(include)?
      1. cp -r /mnt/eed/ad-build/registry/epics-base/R7.0.8/rocky9/epics-base/ /build/

      2. # If this works add to .bashrc because this'll be dev image
         export EPICS_BASE=/build/epics-base
         export EPICS_HOST_ARCH=$(${EPICS_BASE}/startup/EpicsHostArch)
         export PATH=${EPICS_BASE}/bin/${EPICS_HOST_ARCH}:${PATH}

      3. Works for binaries, need to try building simple ioc with it.

         Code Block
         language bash
         mkdir -p /build/testIoc cd /build/testIoc makeBaseApp.pl -t example testIoc makeBaseApp.pl -i -t example testIoc make cd iocBoot/ioctestIoc chmod u+x st.cmd ./st.cmd

         Building works, and can run the ioc. 

         Code Block
         language bash linenumbers true collapse true

      4. Now need to try asyn as that would need 'include' statements of epics. After this then we can conclude epics can be built/ran in a container, although still unclear if can access s3df pvs?
         1. For registry git clone --depth 1 --branch R4-39 https://github.com/epics-modules/asyn.git

         2. Steps to build asyn

            Code Block
            language bash
            mkdir /build/support/ cp -r /mnt/eed/ad-build/registry/asyn/R4.39-1.0.1/rocky9/asyn/ /build/support/ export LD_LIBRARY_PATH=/build/epics-base/lib/linux-x86_64 # Update asyn/configure/RELEASE # Change EPICS_BASE to point to your epics base =/build/epics-base # Change SUPPORT to point to your support folder = /build/support # Comment out IPAC and SNCSEQ # if get xdr.* missing error, then uncomment TIRPC in configure/CONFIG_SITE dnf --enablerepo=crb install libtirpc-devel # -devel is important, its (developer) and gives header files in /usr/include/rpc yum install -y rpcgen cd asyn/ make

         
         
         1. Now you have the libraries and binaries needed, in /asyn/lib.
         2. try test-ioc with asyn with your guardian 'example' branch
            1. cd /build 
            2. git clone -b example https://github.com/pnispero/Guardian.git
            3. in configure/RELEASE
               1. Update EPICS_BASE   to point to /build/epics-base
               2. Update ASYN to point to /build/support/asyn
            4. make
            5. cd iocBoot/iocGuardianTest/
            6. in st.cmd
               1. Update the shebang to point to #!../../bin/linux-x86_64/Guardian
            7. chmod +x st.cmd
            8. ./st.cmd

            9. Optional:

               Code Block
               language bash
               # Then in the shell you can 'dbl' to get pvs # And in another terminal write to 'device' pv. $ caput FBCK:FB02:GN01:S2DES_TEST 5 # Trigger the 'trigger' pv. $ caput SIOC:B34:GD_PATRICK:SNAPSHOT_TRG_EN 1 # The code will then takeSnapshot(). And your output should be 5

1. 1. 1. 1. Patrick left off here, still gives error. How about try these options
            1. Get the prebuilt one from afs, and upload to ad-build-test github, and download in registry and use that
            2. Get test-ioc to have the basic ioc in there.
      2. How would channel access work if epics is in container? Can it be accessed from main server?
   2. 2) Or try moving everything (/include (.h), /lib (.so/.a), and /bin (binaries)) to according directories
