# 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
