b521659f 1# Makefile template for ROOT dictionary generation
2#
85e53837 3# This is a common include file which handles generation of the ROOT dictionary
4# files. It creates:
5# - the dict.cxx (variable DICTCPP)
6# - the dict.h (variable DICTCPP:.cxx=.h)
7# - optional: the linkdef.h (variable MODULE postfixed by -LinkDef.h)
8#
9# If the MODULE_DHDR variable is set in the package definition lib<module>.pkg
10# to a custom LinkDef file, the automatic generation of the LinkDef header is
11# disabled. Instead, the specified one is used.
12#
b521659f 13# usage:
14# 1. set variable CLASS_HDRS to the class header files
15# 2. set DICTCPP variable to dictionary c++ file name
4a6b4894 16# e.g. <module>-DICT.cxx (<module> replaced by your module name)
b521659f 17# 3. add the source file name to the list of generated sources
18# nodist_lib<module>_la_SOURCES = $(DICTCPP)
4a6b4894 19# 4. add additional include files which are necessary for the compilation
20# of the dictionary files and which are not part of the CLASS_HDRS to
21# the DICTINCLUDE variable
22# 5. include this file from your Makefile(.am)
b521659f 23# e.g. include ../make.dict
