thread in _tags?

[jnfoster]

I had to add

true:thread

to the _tags file to get this package to compile on Linux.

Here's a build from a fresh clone:

Any idea why?

[basus]

Maybe try pkg_threads instead? That's what oasis seems to do.

[jnfoster]

adding true: thread to _tags did the trick.

[arjunguha]

no need to manually hack tags. add thread as a dep in ocamlbuild. works?

[jnfoster]

What does "add thread as a dep in ocamlbuild" mean? Adding it to the BuildDepends section does not work.

[jnfoster]

Ahh, threads not thread. OMG WTF FML.
