Check your .ocamlinit, you must have something mentionning camlp4 in there which is not compatible with ppx.

@trefis

$ cat ~/.ocamlinit

open Core.Std
open Core_bench.Std

Does there anything mention camlp4?

trefis commented 8 years ago

I believe core.syntax is camlp4-related. Try requiring ppx_jane instead?

Great thanks, it works now:)
