Re: [opencog-dev] unbound Variable cog-satisfying-set and loading scm file

[vishnupriyaa31]

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.

Now really  don't know what to do !  :-((

 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.

Re: [opencog-dev] unbound Variable cog-satisfying-set and loading scm file

[vishnupriyaa31]

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


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

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

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.
