Hi experts,

A probably very naive question- I am trying to set up Whizard on Mac OSX in the standard way (configure, make, make install) but I consistently get this error no matter what I try

119 | let a = Array2.map_file fd float64 fortran_layout true dim1 dim2 in
Error: Unbound value Array2.map_file
make[2]: *** [events.cmx] Error 2
make[1]: *** [all-recursive] Error 1
make: *** [all-recursive] Error 1

Do you have any suggestions as to how to get around this?

Thanks in advance,

The map_file functions have been moved from Bigarray to Unix in ocaml 4.08.0. For
inexplicable reasons, our tests missed this ...

It's straightforward to fix, but I need to work on a fix that compiles with the currently
supoorted versions before 4.06.0 as well.

Our tests missed this because we are only using versions 4.07 up to now. I have to say I don't like some of the new policies of the OCaml development team to delete deprecated features in one module already two minor version after the new features in another module have been introduced.
