| # 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 |
