Original bug ID: 4855
Reporter: Dmitry Grebeniuk
Assigned to: @bobzhang
Status: closed (set by @xavierleroy on 2015-12-11T18:21:11Z)
Resolution: fixed
Priority: normal
Severity: minor

Bug description

I'm using a syntax extension that installs to ocamlc -where/dir.
I've tried to use it with

$ camlp4 ... -I +dir pa_someext.cmo ...

but with no success:

Camlp4: Uncaught exception: DynLoader.Error ("pa_someext.cmo", "file not found in path")

However, ocamlc/ocamlopt does handle this correctly:

$ ocamlc -I +dir pa_someext.cmo -o somebin

shows to me that pa_someext.cmo is found and processed.

Looking at camlp4 sources I've figured out why camlp4 doesn't handle +directory notation: function "include_dir" in "$ocamlsources/camlp4/Camlp4/Struct/" doesn't have any special processing of "+directory" syntax.

IMHO every ocaml-related tool (toplevel, compiler, preprocessor) should have the same semantics for -I option.

fixed in revision 13940.
A bit difference is +dir is related to 'camlp4 -where' instead of 'ocamlc -where'
