Is there anyway to specify the path to the annot files when using tuareg-mode in emacs? I am trying to find out the type for my functions and the mode complains with "not annotation file".
My build structure is:
lib
obj
*.o
*.cmi
*.cmx
*.annot
src
*.ml
*.mli
I don't think you can easily configure this: have a look at the caml-types-locate-type-file function in the caml-types.el file in your ocaml installation.
This is the function that searches for .annot files. You can probably edit it to replace the "_build" (which is where ocamlbuild puts the generated files) with obj and be done with that.
A much better option is to define a variable in your .emacs.el, and use it in the caml-types.el file. this way, you could even propose the patch to the ocaml people.
