Thank you for the replies. In type_class.ml and type_class.mli, I replaced (*pp cpp $ARCH_FLAGS *) with (*pp gcc -E $ARCH_FLAGS *). The compilation gets further but now fails with:... ocamlfind ocamlc -package type-conv -c -I +camlp4 -for-pack Bin_prot binable.ml File "binable.ml", line 36, characters 21-46: Unbound type constructor Type_class.writer On Wed, Oct 22, 2008 at 4:16 AM, Mark Shinwell wrote: > On Tue, Oct 21, 2008 at 04:22:09PM -0400, Markus Mottl wrote: > > 2008/10/21 Ashish Agarwal : > > > I am having trouble installing JaneStreet's Core library through godi. > > > On Mac OS X, it fails while installing the prerequisite bin-prot: > > > ... > > >> ocamlfind ocamlc -package type-conv -c -pp "cpp $ARCH_FLAGS " -I > +camlp4 > > >> type_class.mli > > >> File "type_class.mli", line 93, characters 15-16: > > >> Syntax error > > > ... > > > Line 93 of type_class.mli is: > > > MK_BASE(unit) > > > > It's possible that the C-preprocessor works differently on Mac OS X. > > I haven't investigated this yet, but would be grateful if anybody who > > has set up Godi on a Mac could try to find a patch. > > There is something about the preprocessors on Mac OS X which causes cpp to > behave differently from gcc -E; I've hit this before but can't remember the > full explanation offhand.
