Can't use Buffer module in Jenga

[rgrinberg]

Doing something like ignore (Buffer.create 128) in your jengaroot.ml doesn't work:

line 43, characters 12-25:\nError: Unbound module Buffer\n

The jengaroot.ml is an ocaml_plugin plugin.
As explained here such plugins are compiled using the environment embedded with your executable. In the case of jenga the environment is defined in myocamlbuild.ml and doesn't include the stdlib.

To use the Buffer module you can probably use Core.Std.Caml.Buffer. Alternatively you can build your own jenga embedding the cmis from the stdlib.

Thanks for the reply. I will see how I can build my own jenga
executable.

However, the workaround with the qualified Buffer path doesn't work
either.

What's the issue when using the fully qualified path?

[rgrinberg]

You're right. Looks like it's a different issue. The module seem to be there - I can alias it with module M = Core.Std.Caml.Buffer for example. But none of the bindings seem to be present inside the module:

Error: Unbound value Core.Std.Caml.Buffer.create

Core.Std.Caml.Buffer is defined as an alias for the standard buffer module, but the problem is that we dont embed the buffer.cmi for this. So currently, building your own jenga.exe is probably the only solution. Sorry.
