Hello,
Is there a way to get the path to the META file of a package ?
Or will $(ocamlfind query $PKG)/META always do ?
Best,
Daniel

`ocamlfind install` requires that either the META file is installed in
the package directory (so your command will work), or the -metadir
option is passed and the META file is installed in some META-only
directory that is global to the ocamlfind configuration. You can query
this directory with $(ocamlfind printconf metadir) (which returns an
empty line if no such directory is used).
This means that the following logic should always find your package file:
- if $(ocamlfind printconf metadir) is not empty, look at
$(ocamlfind printconf metadir)/META.$PKG
- otherwise look at
$(ocamlfind query $PKG)/META

Thanks. Though it would be nice to have a query flag that implements the logic, rather than each of us reimplementing it.
Best,
Daniel
