# =========================================================================== # 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 # # 2008-04-12 # # COPYLEFT # # Copyright (c) 2008 Sebastian Huber <sebastian-huber@web.de> # Copyright (c) 2008 Alan W.
