ERROR: In procedure opencog-extension

[Brook4846]

My ghost-parse rules execute well. But the test-ghost rules always produce the following error as gibberish as it looks here.

rule => (ghost-parse "u: (why) I have no idea") reply => [2018-09-13 13:15:07:375] [WARN] [GHOST] Did you forget to link a goal to the rule?

rule => (map cog-name (test-ghost "why"))

reply => `[2018-09-13 13:16:57:033] [INFO] [GHOST] Say: "I have no idea"

What could possibly be causing it?

Hi @Brook4846, I couldn't reproduce this issue, was there any other rule in the system? What modules had been loaded?

[Brook4846]

Prior to the above commands I mentioned, I loaded the following modules on guile with no error. (use-modules (opencog) (opencog nlp) (opencog nlp relex2logic) (opencog openpsi) (opencog ghost) (opencog ghost procedures)) My relex server is running perfectly.

[amebel]

Unbound variable: prt-say-text implys that (opencog eva-behavior) module is needed. Maybe you made changes to the code that uses it, and forgot to import the module? or maybe you have a stale guile-cache, that rm -rf ~/.cache/guile/ may fix.

[simonmekit]

Thanks @AmeBel, It seems the error comes when using prior versions of repos. and (use-modules (opencog eva-behavior)) solves the issue as you mentioned. Also, pulling the latest repos for cogutil, atomspace and opencog will work fine without the error mentioned by @Brook4846, yet a WARNING message appears only the first time we run (test-ghost "...") like this:

[amebel]

Either you are starting the cogserver without configuration file, or the path to it isn't correct.

[simonmekit]

The best ways to run Ghost would be using this procedure. However, I think one can ignore the warning message if he/she want to run ghost without using ECAN.
