Hey Steve! Thanks for the reminder...I've yank the 3.12.1 compilers from the OPAM repository, as they're now well deprecated.  The switch to 4.x was quite easy, and there are many, many performance and stability improvements in the new tree.

I'd recommend 4.01.0dev+mirage-xen to play with.  It gives you the trunk version with new compiler intrinsics that Pierre put in to optimise handling of low-level int16/32/64s.  It'll be what the first alpha release uses.

(documentation update on the website coming as soon as mirari has first release, real soon now!)

Happy to be a guinea pig. :-)

I switched to 4.01.0dev+mirage-unix but it looks like xenstore is requiring a newer version of cstruct than is provided?

Is `mirage` the correct thing to install if I want to build a mirage app? I notice that mirage-www is not in OPAM any longer.

$ opam list |grep mirage

Available packages for 4.01.0dev+mirage-unix:

mirage                     --  Mirage stdlib

mirage-fs                  --  Mirage filesystem utilities

mirage-net                 --  Mirage TCP/IP networking library

oasis-mirage               --  This is a fork of OASIS with support for native output-obj.

$ opam install mirage

The following actions will be performed:

 - install ounit.1.1.2 [required by mirage]

 - install cstruct.0.5.2 [required by mirage]

 - install xenstore.1.1.0 [required by mirage]

 - install mirage.0.6.1
