This works fine on Linux.

Maybe this is the -pack option not working on OSX?

I don't think -pack worked on OSX until a more recent version of ocaml 
3.09. Which one are you using?

Can you try building Dypgen directly from the dypgen tarball using

I have NO idea what _camlParser is. A grep on lpsrc does not
reveal any symbol 'camlParser'.

This looks like an Ocaml bug .. weird that this thing builds
on Linux, and builds on your OSX box using the dypgen makefile,
but not the Felix build scripts.

The Felix build scripts ARE different .. but the effect should
be the same. Any which way it should either fail on all platforms
or build on all platforms .. there's no C code here, and Ocaml
is supposed to be portable.

Somewhere... someone lied.

Haha, just kidding. The difference is that the tarball uses ocamlc and
flx here is using ocamlc.opt. Could that be relevant?

As I understand it:

No. ocamlc.opt and ocamlc are functionally equivalent.
The only difference is ocamlc is compiled with ocamlc,
whereas ocamlc.opt is compiled with ocamlopt.

In other words, ocamlc.opt is faster because it is
built as native code, but they're built from the
same ocaml sources. Bootstrapping is cool!

In fact there ARE differences between ocamlc
and ocamlopt built code, apart from speed:
for example bytecode supports dynamic loading
of bytecode whereas native code does not ..
but this shouldn't affect ocamlc.

However, -pack MAY be different; it is a new feature
and didn't work on any processor other than x86 originally,
so this might be a difference. -pack does nasty stuff
with native code which requires arcane knowledge of 
object files, whereas with bytecode it's the same on
all platforms.

The -pack option 'packs' several object files into
a single object file and makes the submodules
of a the new master file.

For native code -for-pack has to be specified,
whereas it isn't used with bytecode -- so there's
a difference between ocamlc and ocamlopt .. but this
is related to the object file formats and what information
they contain (bytecode contains what ocaml wants it to,
whereas native code is machine binary and is restricted
by the platform linker format).

Can we disable -pack?
Can I fall back to ocamlc? How?

I can reproduce this on my mac, in ocaml 3.09.3. It works with just 
ocamlc though. We can turn off ocamlopt by setting this:

NATIVE_CODE_COMPILER=0

in config/ocaml_config.py. I'll poke around some more to see if there's 
a real fix.

In the next version of dypgen I will get rid of -pack, because it

I'm not sure if it's a pack issue. I can take your Makefiles and get it 
to work using ocamlopt, so I think it's a problem in our build system.

Ahem .. the lines are backwards -- that's a huge dyslexia :)

So the bug in Ocaml is, on OSX we use:

ocamlopt.opt  -w yzex -warn-error FDPSU  -pack -o dypgen/dyplib/dyp.cmx
dypgen/dyplib/sig.cmi dypgen/dyplib/gs.cmx
dypgen/dyplib/priority_by_relation.cmx dypgen/dyplib/automaton.cmx
dypgen/dyplib/parser.cmx 

but we needed:

ocamlopt.opt  -w yzex -warn-error FDPSU  -I dypgen/dyplib -pack -o
dypgen/dyplib/dyp.cmx dypgen/dyplib/sig.cmi dypgen/dyplib/gs.cmx
dypgen/dyplib/priority_by_relation.cmx dypgen/dyplib/automaton.cmx
dypgen/dyplib/parser.cmx
