  7. # AX_BOOST_FILESYSTEM
  8. #
  9. # DESCRIPTION
  10. #
  11. # Test for Filesystem library from the Boost C++ libraries. The macro
  12. # requires a preceding call to AX_BOOST_BASE. Further documentation is
  13. # available at <http://randspringer.de/boost/index.html>.
  14. #
  15. # This macro calls:
  16. #
  17. # AC_SUBST(BOOST_FILESYSTEM_LIB)
  18. #
  19. # And sets:
  20. #
  21. # HAVE_BOOST_FILESYSTEM
