Error running (use-modules (opencog eva-behavior))

[Eyob]

When I ran the below in guile before running ghost

(use-modules (opencog eva-behavior))

it raises the following error below but I think what is missing is the module (opencog pointmem). How do I install pointmem??


Here is the error


scheme@(guile-user)> (use-modules (opencog eva-behavior))
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-auto-compile argument to disable.

Ok, I solved it myself. What was missing was octomap (https://github.com/OctoMap/octomap/wiki/Compilation-and-Installation-of-OctoMap).

Seems the spactime and/or spatial component of opencog needed that dependency.
 
I wonder that dependency need to be listed at https://github.com/opencog/opencog

There is a check for octomap when compiling the C++ code. There's no run-time check.  I'm not sure what a good fix for this is.  --linas
