I think Jane Street Core team added the "-w @Aemr-28" flags. They did
it in myocamlbuild.ml section not managed by OASIS. The only solution
is to change by hand.

I CC the core mailing list which will provide you more information
about this issue (I have the same kind of issue because of "@" on
Windows).

[Gabriel Scherer]

I react to "the @ issue on Windows", because I'm the one to blame in this case.

This was discussed on the OCaml bug tracker (
http://caml.inria.fr/mantis/view.php?id=5312 ) and later on the Caml
mailing-list ( http://www.mail-archive.com/caml-list@inria.fr/msg01993.html
), and it was decided to remove support for @responsefiles from OCaml
to solve that conflict with the warning specification syntax.

Fate assigned the bug to me, but I've been busy with other things and
have not implemented it (if someone wants to help on this, feel
free!). As we're late in the release process, I don't think it would
go in for 4.00, so the best bet for now is to consider this warning
specification unportable and use -warn-error instead.

I welcome feedback on such issues on the bugtracker or mailing-list;
feedback helps setting good priorities.
Sorry for not taking care of this earlier.

Mmmh. I'm a little bit stuck (too lazy to delve into odb.ml, in fact).  

Tried to remove the flag manually in `~/.odb/install-type_conv/type_conv-108.00.01/myocamlbuild.ml` but it seems that when I reissue `odb --unstable type_conv`, odb restarts everything from scratch, download included.  

There is `--get` that only downloads and extracts the package is there a flag like `--no-get` to be able to start from that state in odb ?  

Best,

Daniel

Hi Daniel,

> Tried to remove the flag manually in `~/.odb/install-type_conv/type_conv-108.00.01/myocamlbuild.ml` but it seems that when I reissue `odb --unstable type_conv`, odb restarts everything from scratch, download included.

You can simply reissue:

ocaml setup.ml -build
ocaml setup.ml -install

in ~/.odb/install-type_conv/type_conv-108.00.01/

that should work.

> There is `--get` that only downloads and extracts the package is there a flag like `--no-get` to be able to start from that state in odb ?

at the moment I can't look into that, but I hardly can remember if
that was possible.

At the moment, the way to have odb.ml install a package from a local 
directory is to add it to your packages file, like this:

type_conv dir=~/.odb/install-type_conv/type_conv-108.00.01

At the moment, odb allows the use of tarballs (http or local) on the 
command line, but doesn't properly handle local directories.  I'll see 
if I can add support for this quickly.

Thanks. That did it --- however it installed the whole thing in `/usr/local/lib/ocaml/site-lib/type_conv/`, but I don't really care.  

Except that problem, oasis 0.0.3 installed fine with odb and ocaml 4.00.0+beta2 on osx 10.7.4 simply with :

    ocaml odb.ml --unstable oasis

Best,

Daniel

Strange - it should do the right thing, perhaps you have another
installation of OCaml, usually I do everything from home when using odb,
so the "bin" directory containing current ocaml binaries is a just below
the root of the distro. Otherwise you can always specify the location in the
configure step.

Don't hesitate to propose patches for odb.ml, the code is fairly simple
and completely standalone. Also, github is very nice for collaborating.

Another way would be to create your own tarball, already patched, then 
give it to odb via your ~/.odb/packages file.

[Damien Doligez]

I think I'm the one to blame here: I chose the @ character for
this purpose.

A workaround for the authors of the original software (and indeed
a portability note for all OCaml software):

Instead of "-w @Aemr-28", you can use "-w A@Aemr-28", which will
do exactly the same thing, without triggering the bug.  Just avoid
having the @ at the beginning of the argument.
