EPICS Base Structure
Acquiring and Unpacking the EPICS Source
Prepare your system
You need make, c++ and libreadline to compile from source. On Linux you can use "apt-get install".
Install EPICS
epics@workstation:~$ cd $HOME/EPICS
epics@workstation:~$ git clone --recursive https://github.com/epics-base/epics-base.git
epics@workstation:~$ cd epics-base
epics@workstation:~$ make
Set environment variables
After compiling you should put the path into $HOME/.bashrc by adding the following to either one of those files:
export EPICS_HOST_ARCH=$(${EPICS_BASE}/startup/EpicsHostArch)
export PATH=${EPICS_BASE}/bin/${EPICS_HOST_ARCH}:${PATH}
Tip:
The export command above will be useful for future software development. Add it to the ~/.bashrc file with a text editor (such as nano ~/.bashrc).
Test EPICS
Now log out and log in again, so that your new path is set correctly. Alternatively, you can execute the three lines above beginning with export directly from the terminal.
Run softIoc and, if everything is ok, you should see an EPICS prompt.

You can exit with ctrl-c or by typing exit.
