Description Noah Ready-Campbell 2009-05-25 04:06:03 UTC

I emerged extlib, but found it unusable initially.  For example:

# open Std;;
Unbound module Std

I was able to get the "Std" module to work by copying the std.cmi and std.mli files from /usr/lib/ocaml/site-packages/extlib (where they were by default) to /usr/lib/ocaml.


I am new to OCaml, so I may be doing something wrong, but it was a bit of a hurdle.

Reproducible: Always

Steps to Reproduce:
1. emerge dev-ml/extlib
2. try to use it (e.g. open Std;;)

Actual Results:  
I get an error stating that OCaml can't find the module in extlib.

Expected Results:  
It should have found the module properly, and I should have been able to use it.

Actually, moving the .mli and .cmi files didn't fix the problem.  After the copy, "open" works fine, but you can't actually use the contents of the modules.  I just get "Reference to undefined global `Std'".

I think I must be doing something wrong, but it would be pleasant if emerging extlib resulted in a workable library, or maybe further instructions on using it properly.

Well, in case anyone finds this, you can get extlib to work properly in the top loop like this:

ocaml -I `ocamlfind query extlib` extLib.cma

You can can get it it work properly with ocamlbuild like this:

ocamlbuild -cflags -I,/usr/lib/ocaml/site-packages/extlib/ -lflags -I,/usr/lib/ocaml/site-packages/extlib/ -lib extLib target

where target might be something like "test.native", and your working directory for the command has "test.ml" in it.

yes; thats the point of installing it there, so that ocamlfind (findlib) helps finding it.
