[MLton-user] Using MinGW version of MLton on Vista

[John Reppy]

Thanks for the pointer.  The r6811 msi version works better for me, although it installs its own copy of MSYS and MinGW,
which seems strange.  The problem that I'm hitting now is that MLton is reporting a syntax error on a mlb file (the file in
question has been used successfully on both Linux and Mac OS X systems).

$ make
/bin/mlton -const 'Exn.keepHistory true' -mlb-path-map /c/Users/t-johrep/Work/sml3d/src/sml3d-path-map -link-opt '-L/c/Users/t-johrep/Work/sml3d/windows/lib -lglut32 -lglu32 -lopengl32 /c/Users/t-johrep/Work/sml3d/src/glut/glut-glue.o'  -output ortho main.mlb
Error: main.mlb 27.0.
  Parse error.
compilation aborted: parseAndElaborate reported errors
make: *** [ortho] Error 1

The MLB file is

    16    $(SMLXD_LIB)/glut/glut.mlb
    17    $(SMLXD_LIB)/util/util.mlb
    18
    19    main.sml
    20
    21  in
    22
    23    structure Main
    24
    25  end
    26

So the error is at the end of the file.

Is this a known problem?  Should I be using a different version of MLton?

I don't know of anyone who has tried MLton/MinGW on Vista yet. Tom Murphy reported problems using MLton/cygwin on Vista, but I don't know if this was ever resolved. You could >try< a newer MLton, for example the msi installer on mlton.org/Experimental<http://mlton.org/Experimental>, but I doubt it will work either.

I would be happy to look into this for you, as it seems I am currently the MinGW port maintainer. :-) However, as I don't have Vista, it would be very slow going. I would suggest using a non-Vista machine to build a debug version of hello-world (compiled with -g and linked to the -dbg libraries). Then, run that hello world in gdb and report back to us the stack trace.

Or, convince your employers to buy a MLton developer a copy of Vista.
