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.

         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. Code Block
               language bash
               cd /build

               git clone -b example https://github.com/pnispero/Guardian.git

               in configure/RELEASE

               Update EPICS_BASE   to point to /build/epics-base

               Update ASYN to point to /build/support/asyn

               make

               cd iocBoot/iocGuardianTest/

               in st.cmd

               Update the shebang to point to #!../../bin/linux-x86_64/Guardian

               chmod +x st.cmd

               ./st.cmd

            2. 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
