Question about linking actual rewriter with ocamlbuild

[Kakadu]

There is a command to build custom rewriter using ocamlfind but I currently have some troubles making things work

The problem is that current approach relies on the fact that ppx plugin is built as findlib library. And if I'm developing syntax extension in my project and want to run some tests than I need to compile syntax extension and after that compile tests with adjusted OCAMLPATH variable. I tried to pass cmxa manually and remove dependency on findlib package but it seems that the order of cmxa's matters and only way to do every all right is to reference PPX package. With this approach there is also an issue with dependencies: tests should be recompiled when the package changes and this currently doesn't work as I want.

Can you give me a piece of advice without recommending switching to dune?

P.S. This is a question mentioned in #18

You can try replacing -package ppxlib.runner by my-rewriter.cmxa runner.cmx where runner.ml contains:

Ppxlib.Driver.standalone ()

then things should be linked in the right order

@diml It is very helpful. Do you think about adding it to the README?

that seems fine to me. Would you mind writing a PR? :)
