  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.) +# This macro searches for a SWIG installation on your system. If found, +# then SWIG is AC_SUBST'd; if not found, then $SWIG is empty. If SWIG is +# found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd. # -# 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. +# 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.

If the version argument is given (e.g. +# 1.3.17), AX_PKG_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 +# As usual, action-if-found is executed if SWIG is found, otherwise +# action-if-not-found is executed. # -# LAST MODIFICATION +# In configure.in, use as: # -# 2008-04-12 +# AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ]) +# AX_SWIG_ENABLE_CXX +# AX_SWIG_MULTI_MODULE_SUPPORT +# AX_SWIG_PYTHON # -# COPYLEFT +# LICENSE #
