That's currently broken due to a bug in obuild. You need to downgrade to cow.0.5.5 (just "opam install cow.0.5.5").

I'll be removing the dependency on obuild soon, but it's pending a switch to OCaml 4.1.

Thanks for the tip. I've been trying to install ocamlopt package.

I also installed 'camlp4-extra' package and now I got this error (while Installing cow.0.6.1):

Camlp4: Uncaught exception: DynLoader.Error ("xmlm.cma", "file not found in path")

Where can I get this "xmlm.cma", where should it be found?

Please find appended below the full error:

Thanks for your help.

You can solve the issue by:
* pointing OCAMLFIND_CONF environment to the right configuration file
* making sure that the ocamlfind program in your path is the right one (ocamlfind printconf)

this is likely to cause various compilation problems

That should be simply just:

$ opam init
$ opam remote add mirage-dev git://github.com/mirage/opam-repo-dev
$ eval `opam config -env`
$ opam install mirari
$ git clone git://github.com/mirage/mirage-www
$ cd mirage-www
$ make
$ make run
