opam pinning to the git repos. does not help

UnixJunkie commented 3 years ago

maybe related to https://github.com/ocamllabs/ocaml-ctypes/issues/647

UnixJunkie commented 3 years ago

I cannot reproduce, but this is the second time I end up in an opam and system state where ctypes cannot be installed...

UnixJunkie commented 3 years ago

If I opam uninstall ctypes-foreign, then ctypes installs successfully... ?!

yallop commented 3 years ago

The ctypes opam build instructions build the foreign subpackage only if ctypes-foreign is installed.

Just for the record:

opam depext -i ctypes-foreign ctypes # fails with the above error
opam remove ctypes-foreign; opam install ctypes # just works
