Introduction

This is the EPICS base and various modules Configuration Environment for the ALS-U project and my purpose. There are plenty of diverse ways we can do this. However, it is designed for me to minimize my limited resources to support the reproducible EPICS environment in various platforms. I want to use almost pure Makefile instead of packages, and continuous integration tools, such as Ansible, Conda, Puppet, and even shell scripts. Unfortunately, I used "shell tricks" within Makefile rules, but I tried to use the generic Makefile rules as much as possible. I want a system that works without looking for their dependencies over the next ten years.

TL;DR

That you know, one should install all relevant packages for the EPICS base and modules.

Note that due to pyDevSup, one must carefully set up its python version. The minimum required package is numpy. Please check the .github/workflow action files for the relevant packages.

Note that due to measComp, one needs to set up a vendor library. Please check https://github.com/jeonghanlee/uldaq-env with /usr/local installation path.

Note that due to pvxs, one needs to run make symlinks mandatory. It allows us to use the proper path for pvxs executable files and libraries with the environment. We use the bundle libevnet instead of a system library.

  • additional makefile rules
make exist             : Show Base and Modules Installation Path  (one can use `LEVEL` argument, e.g., `make exist LEVEL=4`)
make init.modules      : Generate dynamic modules variables and clone all
make conf.modules      : Make conf.modules.show will print out all local configuration files.
make conf.modules.show : Show all local configurations (RELEASE.local, CONFIG_SITE.local, and so on)
make clean.modules     : Some modules have the infinite compiling loop, so we have to clean up existing things within git repositories.
make build.modules     : Build and install each module into its installation location
make install.modules   : We may not need this rule because of the standard EPICS building system default could be to build and install
make uninstall.modules : Execute uninstall within each module source, and remove the installed module directory.
make exist.modules     : Show where the modules are installed.
make vars              : Print all important variables
make PRINT._var_name   : Print the selected variable
make symlinks.modules   : Create / Overwrite symbolic links for all modules defined within active configuration. Remove all dead links.
  • Delete all download sources
make distclean.modules

A Module Setup

If we define each module properly, all module build rules are generated automatically. For example,

make build.iocStats

make clean.StreamDevice

make install.asyn

The rule name is used in the form as

build_name.module_name

where build_name is one of build, install, clean, and uninstall And module_name is the module directory name without -src suffix.
