In 5.00.X you could say 'ghc-pkg --show-package=std --field=library_dirs' but now in 5.02 this just says "$libdir" because we made the package.conf file independent of the install location to solve some problems with installation on Windows. The value of $libdir (aka $topdir) is passed to GHC using the -B option, which on Unix is hardwired into the shell wrapper script 'ghc'. So we should have an option like '--print-libdir' to get at the value of $libdir, and then you can find out the locations of the actual libraries and include files by interrogating ghc-pkg. ok?

Right, but if all ghcs always use /usr/include/ghc then you can only run the ghc that is the `current alternative' -- if you try to run the other one, it will find the wrong libraries (which may or may not work). So, without root intervention to change the current alternative, you could still only run one, which makes having multiple versions installed a lot less useful. And, even if ghc itself did not use /usr/include/ghc, your multilingual makefile would get the wrong includes if you used the non-current-alternative ghc. -- Mieszko ___ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

And now that location is hard-coded in my Makefile. What about (finally!) adding the `--print-include-path' and `--print-library-path' switches to ghc? That would be a clean solution, IMO.

For ghc >= 5.00, but not on Windows:
#!/bin/sh
GHCDIR=`grep '^libdir' ${whichGHC} | head -1 | sed 's/^libdir=.\(.*\)./\1/'`if
[ ! -d $GHCDIR/imports ]
then GHCDIR=`grep '^TOPDIROPT' ${whichGHC} | head -1 | sed
's/^TOPDIROPT="*-B\([^";]*\).*/\1/'`
fi
echo $GHCDIR/imports
For ghc < 5.00, including on Windows:
#!/bin/sh
GHCDIR=`grep '^\$libdir=' ${whichGHC} | head -1 | sed
's/^\$libdir=[^/]*\(.*\).;/\1/'`
if [ -d $GHCDIR/imports ]
then echo $GHCDIR/imports
elif [ -d $GHCDIR/lib/imports ]
then echo $GHCDIR/lib/imports
echo echo unknown
fi

Yes, I guess GHC should really understand C++ file suffixes.

Thanks, I'll look into fixing that.

Won't help, my GHC is installed at /usr/lib/ghc-5.02/, exactly where the
Debian package put it. And now that location is hard-coded in my Makefile.

GHC didn't seem to want to compile my .cpp file -- instead it quietly and
successfully did nothing. Also I had to do this:
extern "C" {
#include "Rts.h"
}
...which I've recently entered a bug in SourceForge about.

On a Unix platform, the 'ghc' wrapper script contains the installation directory, which is passed as an option to the ghc-5.02 binary proper. On Windows platforms, there isn't a wrapper - ghc figures out the install location from the location of its binary. I've wondered at various times in the past whether there ought to be a link from /usr/local/includes/ghc to /usr/local/lib/ghc-5.02/includes. But the usual way around this problem is to use 'ghc' as your C compiler - then the -I flag gets injected automatically.
