# SYNOPSIS
|
|
#
|
|
# AX_PKG_SWIG([major.minor.micro], [action-if-found], [action-if-not-found])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# 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.
|
|
#
|
|
# 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), AX_PKG_SWIG checks that the swig package is this version number
|
|
# or higher.
|
|
#
|
|
# As usual, action-if-found is executed if SWIG is found, otherwise
|
|
# action-if-not-found is executed.
|
|
#
|
|
# In configure.in, use as:
|
|
#
|
|
# 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
