Synopsis

  `AC_caolan_SEARCH_PACKAGE(PACKAGE, FUNCTION, LIBRARY LIST, HEADERFILE [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])`

Version

  1.2 (2002/12/12) Installed_Packages @ ac-archive-0.5.39

Author

  Caolan McNamara <caolan@skynet.ie>

Description

  Provides --with-PACKAGE, --with-PACKAGE-include and --with-PACKAGE-libdir options to configure. Supports the now standard --with-PACKAGE=DIR approach where the package's include dir and lib dir are underneath DIR, but also allows the include and lib directories to be specified seperately

  adds the extra -Ipath to CFLAGS if needed adds extra -Lpath to LD_FLAGS if needed searches for the FUNCTION in each of the LIBRARY LIST with AC_SEARCH_LIBRARY and thus adds the lib to LIBS

  defines HAVE_PKG_PACKAGE if it is found, (where PACKAGE in the HAVE_PKG_PACKAGE is replaced with the actual first parameter passed) note that autoheader will complain of not having the HAVE_PKG_PACKAGE and you will have to add it to acconfig.h manually

  with fixes from... Alexandre Duret-Lutz <duret_g@lrde.epita.fr> Matthew Mueller <donut@azstarnet.com>
