Page History

The purpose of this page is to create a quick reference for all the macro (and variable) definitions we find in the EPICS build environment.  Often times, the names of the macros do not give much of a clue of their purpose, and sometimes the names are misleading.  Makefiles typically have the name "Makefile" but in EPICS they can have just about any name.  For example, RELEASE or CONFIG or RULES.  I still call them Makefiles as their syntax is defined by the Makefile parser program "make".

Terms

An EPICS application is an application that is linked with EPICS libraries.

An EPICS module is a library (.a or .so) that are specifically designed for the EPICS environment.  Typically modules are statically linked to the EPICS application.

A package is a standard OS (e.g. Linux) library that is linked with an EPICS application.  An example is boost or an XML parsing library.

Application

src Directory

If you're building an app (not a module, not a library), your app will have a Makefile in its src directory.
