camlp4rf allows __LOCATION__ in macros. Here is the output of "camlp4rf Io.ml": let () = ignore (Loc.of_tuple ("Io.ml", 1, 0, 11, 1, 0, 23, false)) The problem here is just that the Loc module is not defined. You have to write: open Camlp4.PreCast; before using __LOCATION__. |

why should use __LOCATION__ brings dependency on the whole camlp4? |

It doesn't. You can write you own Loc module. |
