[Caml-list] problem installing janestreet core through godi
Ashish Agarwal
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)
On a Red Hat Enterprise Linux system, bin-prot successfully installs.
However, janestreet-core fails:
..
> ocamlfind ocamlc -package res,sexplib,bin_prot,threads -c -thread -dtypes
-for-pack Core -dtypes -I +camlp4 -I . binable.ml
> File "binable.ml", line 12, characters 21-47:
> Unbound type constructor Map_to_safe.sw_arg
..
Line 12 of binable.ml is
val bin_sw_arg_t : binable Map_to_safe.sw_arg

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.

janestreet-core is out of date, and a new version will be released
within the next few weeks. You might want to downgrade the bin-prot
package installed in your Godi tree to an older version.

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. You can see the difference, for example, if you
try to use the ## operator. Does everything work if you get everything
to use gcc -E for preprocessing?

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

Great! This means that this fix solved the problem. You have now run
into another, known one: the "core" library is badly out of date, and
needs to be updated to work with newer releases of bin-prot. We will
make a release within (probably) the next few weeks. In the meanwhile
you might want to downgrade bin-prot to make it work with "core".
I'll add a patch to bin-prot to make it work on Macs in the meanwhile...
Regards,
Markus

Another option is to use /usr/bin/cpp-4.2 instead of /usr/bin/cpp.
After making symbolic link ~/bin/cpp to /usr/bin/cpp-4.2 (and put `~/
bin' in PATH), I succeed to build bin-proto without source code
modification.
