# driver.makefile
#
# This generic makefile compiles EPICS modules (drivers, records, snl, ...)
# for all installed EPICS versions.
# Read this documentation and the inline comments carefully before
# changing anything in this file.
#
# Usage: Create a Makefile containig the line:
#        include /ioc/tool/driver.makefile
#        Optionally add variable definitions below that line.
#
# This makefile automatically finds the source file (unless overwritten with
# the SOURCES variable in your Makefile) and generates a module consisting
# of a library and .dbd file for each EPICS version and each target architecture.
# Therefore, it calls itself recursively.
#
# - First run: (see comment ## RUN 1)
#   Find out what to build
#   Iterate over all installed EPICS versions
#
# - Second run: (see comment ## RUN 2)
#   Find the sources etc.
#   Include EPICS configuration files for this ${EPICSVERSION}
#   Iterate over all target architectures (${T_A}) defined for this version
#
# - Third run: (see comment ## RUN 3)
#   Check which target architectures to build.
#   Create O.${EPICSVERSION}_${T_A} subdirectories if necessary.
#   Change to O.${EPICSVERSION}_${T_A} subdirectories.
#
# - Fourth run: (see comment ## RUN 4)
#   Compile everything.
#
# Module names are derived from the directory name (unless overwritten
# with the MODULE variable in your Makefile).
# A LIBVERSION number is generated from the latest CVS or GIT tag of the sources.
# If any file is not up-to-date in CVS/GIT, not tagged, or tagged differently from the
# other files, the version is a test version and labelled with the user name.
# The library is installed to ${EPICS_MODULES}/${MODULE}/${LIBVERSION}/lib/${T_A}/.
# A module can be loaded with  require "<module>" [,"<version>"] [,"<variable>=<substitution>, ..."]
#
# User variables (add them to your Makefile, none is required):
# MODULE
#    Name of the built module.
#    If not defined, it is derived from the directory name.
# SOURCES
#    All source files to compile. 
#    If not defined, default is all *.c *.cc *.cpp *.st *.stt in
#    the source directory (where you run make).
#    If you define this, you must list ALL sources.
# DBDS
#    All dbd files of the project.
#    If not defined, default is all *.dbd files in the source directory.
# HEADERS
#    Header files to install (e.g. to be included by other drivers)
#    If not defined, all headers are for local use only.
# EXCLUDE_VERSIONS
#    EPICS versions to skip. Usually 3.13 or 3.14
# ARCH_FILTER
#    Sub set of architectures to build for, e.g. %-ppc604
