Install fails with 4.04.0 compiler

[burnoutberni]

Hi, Disclaimer not an ocaml person here, just wanted to compile a package that depends on websocket.2.9 and ran into problems.

Tried to install websocket.2.9 on armhf (Raspberry Pi) with 4.04.0 first which failed, then tried installing it on amd64 with 4.02.0 which worked, but as panama requires 4.04.0 I updated to that and now I get the same error message as on the Raspberry Pi when compiling websocket.

I deduct that that means there's a problem with websocket.2.9 but maybe I'm also missing a native dependency or something, any help would be greatly appreciated.

[ERROR] The compilation of websocket failed at "ocaml pkg/build.ml native=true
        native-dynlink=true lwt=true async=false async_ssl=false nocrypto=false
        cryptokit=false test=false".

I can't reproduce. Which version of conduit are you on? Could you try pinning conduit to version 0.15.0 (the latest)?

This solved the problem for me. Thank you very much.
