| # 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 |
