G'day all.

Has anyone come up with some magic to let automake play nice with Haskell compilers (ghc 5 or nhc 98 preferred)? gtk+hs and gtk2hs use the macro written by Michael Weber for his hMPI binding to check for a sufficient large version number. Otherwise, the normal AC_PATH_PROG is your best bet. This is how I look for ghc and ghc-pkg:

dnl Check for GHC-5.00 or greater. dnl (The next command is not executed, if $HC is already set.) AC_PATH_PROG(HC, ghc, ghc-not-found) if test $HC = ghc-not-found; then AC_MSG_ERROR([ Could not find GHC! This is the only supported compiler. You need GHC 5.00 upwards.]) fi GHC=$HC dnl Check GHC details. AC_MSG_CHECKING([version of GHC]) GHC_VERSION=`$GHC --version | $SED "s/[[a-zA-Z ,]*\([0-9.]*\)[a-zA-Z ]]*/\1/"` AC_MSG_RESULT([$GHC_VERSION]) GTKHS_PROG_CHECK_VERSION($GHC_VERSION, -lt, 5.0.0, [ AC_MSG_ERROR([I need the FFI of GHC 5.00 upwards!])]) AC_MSG_CHECKING([new module system]) NEW_MODULE_SYSTEM=no; GTKHS_PROG_CHECK_VERSION($GHC_VERSION, -ge, 5.04.0,[NEW_MODULE_SYSTEM=yes;]); AC_MSG_RESULT([$NEW_MODULE_SYSTEM]) GHCBARE=`basename $GHC` GHCDIR=`dirname $GHC` GHCPKGNAME=ghc-pkg`echo $GHCBARE | $SED s/ghc//` dnl Check for ghc-pkg. Use the one that is in the same directory and dnl version suffix as the specified compiler. AC_PATH_PROGS(GHCPKG, $GHCPKGNAME ghc-pkg, ghcpkg-not-found, $GHCDIR) if test $GHCPKG = ghcpkg-not-found; then AC_MSG_ERROR([ghc-pkg not found. (But ghc exists!?)]); fi Cheers, Axel.
