unbound Variable cog-satisfying-set and loading scm file

[vishnup...@gmail.com]

Hello,

my ~/.guile has 

(use-modules (ice-9 readline)) (activate-readline)

(add-to-load-path "/usr/local/share/opencog/scm")

(add-to-load-path ".")

(use-modules (opencog))

(use-modules (opencog query))

(use-modules (opencog exec))

(load-from-path "opencog.scm")

1.     When i run,

  -->(define find-body(GetLink(ChoiceLink(EvaluationLink(PredicateNode "tweet-info")(ListLink(VariableNode "$body")(ConceptNode "Montgomery"))) (EvaluationLink(PredicateNode "tweet-info")(ListLink (VariableNode "$body")(ConceptNode "Washington"))))))

 -->(cog-satisfying-set find-body),

        it throws a following error:

Backtrace:

2. I have the following in my testAtomspace.scm file

(EvaluationLink

   (PredicateNode "tweet-info ")

   (ListLink

      (ConceptNode "[-77.0325, 38.8749]")

      (ConceptNode "US")

      (ConceptNode "Washington")

      (ConceptNode "Attend the #LiteraryExperience #NYFW edition on Sept 8th. VIP tickets available now at https://t.co/4rNiQSchnp")

   )

)

(EvaluationLink

   (PredicateNode "tweet-info ")

   (ListLink

      (ConceptNode "")

      (ConceptNode "")

      (ConceptNode "")

      (ConceptNode "RT @Brandonwoelfel: Photo of me taking a photo https://t.co/i65A4uNr8w")

   )

)

when i run 

 (add-to-load-path "/home/vishnu/Documents/opencog_relatedPackages/opencog/build")

(add-to-load-path "/home/vishnu/Documents/opencog_relatedPackages/opencog/opencog/scm")

(load-from-path "testAtomspace.scm")

It always shows only the last part :  

(EvaluationLink

   (PredicateNode "tweet-info ")

   (ListLink

      (ConceptNode "")

      (ConceptNode "")

      (ConceptNode "")

      (ConceptNode "RT @Brandonwoelfel: Photo of me taking a photo https://t.co/i65A4uNr8w")

   )

)

Is it right? or am i missing anything?

Thanks in advance ,

Vishnu

You almost surely should not be doing this last line.

 

1.     When i run,

  -->(define find-body(GetLink(ChoiceLink(EvaluationLink(PredicateNode "tweet-info")(ListLink(VariableNode "$body")(ConceptNode "Montgomery"))) (EvaluationLink(PredicateNode "tweet-info")(ListLink (VariableNode "$body")(ConceptNode "Washington"))))))

 -->(cog-satisfying-set find-body),

        it throws a following error:

Beats me, it works for me. My best guess is that some earlier compile failed, and/or you did not do a "make install" after some compile, or that possibly you have some old version of the query module that does not contain cog-satisfying-set.  You can verify by hand that its there, in /usr/local/share/opencog/scm/opencog/query.scm

Looking at that file, it tries to load two shared libraries: libexecution and libquery berhaps one or both of these are borked or not installed.    You can verify these by saying 

ldd -r /usr/local/lib/opencog/libexecution.so  and also libquery and make sure there are no errors about unlinked functions.

It is also possible that, by directly loading opencog.scm, which you should never do, that you clobbered the LTDL_LIBRRY_PATH causing the two libraries not to be found.

2. I have the following in my testAtomspace.scm file

when i run 

 (add-to-load-path "/home/vishnu/Documents/opencog_relatedPackages/opencog/build")

(add-to-load-path "/home/vishnu/Documents/opencog_relatedPackages/opencog/opencog/scm")

(load-from-path "testAtomspace.scm")

It always shows only the last part :  

That's normal.  You can suppress even that by adding *unspecified* to the bottom of the file, and so nothing at all will be printed.

What to do now?

But the thing is,  i have newly installed  and built atomspace, cogutils and opencog in a new laptop. Still i got the unbound variable error.

Hmm. actually, that's normal. Its not fixable, due to a design flaw in CMake. But that does not explain your crash, since I have the same thing, and it works for me.

Did you remove  (load-from-path "opencog.scm")?

Apparently, I sent you on a wild goose chase: the above  (load-from-path "opencog.scm") is the cause of your problems.  It places you into a model context, where the global context is not visible. Its absolutely the wrong thing to do. 

I guess you did this, because you found instructions suggesting this, somewhere... where?  Those instructions need to be fixed.

Yeah i removed the line (load-from-path "opencog.scm"). But still got the same unbound variable error.  :-((

I followed the instructions  as in  http://wiki.opencog.org/w/Scheme

[vishnup...@gmail.com]

What can i do to fix this this unbound variable cog satisfying set ?

I also tried running the script from Hansonrobotics head, since it will build and everything for us. Hoping that there may not be any error 

But i could not run this, it also threw error

Verifying checksums.
