Haskell loading modules problem in emacs

Question

I have 2 Haskell modules in emacs: Mod1.hs and Mod2.hs

Mod1.hs:

module Mod1 where
...

In the second module i try to import first module:

import Mod1

But get error:

 Could not find module `Mod1':
      Use -v to see a list of the files searched for.
Failed, modules loaded: none.

In emacs i use standard Haskell-mode. Mod1.hs and Mod2.hs files in the same directory.

How can i fix it?

Thank you.

You need to set the search-path of the interpreter running in Emacs to include the directory with your files. In the GHCi interpreter do:

Prelude> :cd /home/you/projects/yourproject

Replacing /home/you/projects/yourproject with the path to your .hs files of course. (Do :!pwd in the interpreter to print the current path.) You should then be able to do:

Prelude> :l Mod2

(Or C-c C-l in the Mod2.hs buffer.) See the GHC user guide for details.

This may help, if you put it in your .emacs:

(setq inferior-haskell-find-project-root nil)

It tells ghci not to move from the current directory.
