[Caml-list] ocamlfind does not find pinned packages

[Helmut Brandl]

Hello list,

I have a package not yet in the opam repository. I install it with ‘opam pin add project .’ which performs sucessfully. It installs the needed binaries in the ‘.opam/system/bin/project’ directory and some library files in the ‘.opam/system/lib/project’ directory.

Now I want to use ‘ocamlfind query project’ to find the library. But ocamlfind always reports project not found. Have I missed some important step?

Regards
Helmut

Did you install a META file in '.opam/system/lib/project' ? Since you are using a system compiler are you sure the right ocamlfind is being invoked ? Try $(command -v ocamfind) and check that you get .opam/system/bin/ocamlfind.  

Best,  

Daniel

Thank you Daniel,

I didn’t know that ocamlfind needs a META file. Even an empty file seem to be sufficient for ocamlfind for a successful application of the query command.
