No implementation provided for Re_pcre #5

Closed boynux closed 5 years ago

boynux commented 5 years ago

I'm trying to use ppx_regexp, but I get this error when trying to compile my app. I already have "re" as a dependency, but not sure what else I'm missing.

ocaml: 4.04.2 opam: 1.2.2

output:

Error: No implementations provided for the following modules:
         Re_pcre referenced from dispatch.cmx

As a side note I'm very new to Ocaml, could be I'm missing something very basic. Thank you

Assuming you are using the latest version (0.4.x), you need re.perl.

Since you are now to OCaml, I would also recommend building with dune, since it will pick up the runtime dependency. To do so, create a file dune next to your source code with something like

(executable
  (name hello)
  (preprocess (pps ppx_regexp)))

and execute it with dune exec ./hello.exe.

Will give it a try and let you know. Thanks for the quick response. btw, this ppx helped me a lot to simplify my code logic!

I'll close this, adding re.perl solved the issue. Thanks for your support!
