cryp.to ac-archive's C++ Support (released)
Test for Filesystem library from the Boost C++ libraries. The macro
requires a preceding call to AX_BOOST_BASE. Further documentation
is available at <http://randspringer.de/boost/index.html>.
This macro calls:
AC_SUBST(BOOST_FILESYSTEM_LIB)
And sets:
HAVE_BOOST_FILESYSTEM
AC_DEFUN([AX_BOOST_FILESYSTEM],
[
AC_ARG_WITH([boost-filesystem],
AS_HELP_STRING([--with-boost-filesystem@<:@=special-lib@:>@],
[use the Filesystem library from boost - it is possible to specify a certain library for the linker
e.g. --with-boost-filesystem=boost_filesystem-gcc-mt ]),
