##### http://autoconf-archive.cryp.to/ac_pkg_swig.html # # SYNOPSIS # # AC_PROG_SWIG([major.minor.micro]) # # DESCRIPTION # # This macro searches for a SWIG installation on your system. If # found you should call SWIG via $(SWIG). You can use the optional # first argument to check if the version of the available SWIG is # greater than or equal to the value of the argument. It should have # the format: N[.N[.N]] (N is a number between 0 and 999. Only the # first N is mandatory.) # # If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks # that the swig package is this version number or higher. # # In configure.in, use as: # # AC_PROG_SWIG(1.3.17) # SWIG_ENABLE_CXX # SWIG_MULTI_MODULE_SUPPORT # SWIG_PYTHON # # LAST MODIFICATION # # 2006-10-22 # # COPYLEFT # # Copyright (c) 2006 Sebastian Huber # Copyright (c) 2006 Alan W.
