make install

outputs the following error

CMake Error at opencog/atomspace/cmake_install.cmake:56 (FILE):
file INSTALL cannot find
"/home/nilg/OpenCog/opencog/opencog/atomspace/atom_types.h".
Call Stack (most recent call first):
opencog/cmake_install.cmake:41 (INCLUDE)
cmake_install.cmake:37 (INCLUDE)

While building opencog I've noticed some warnings (unused-result, unused-variable) that may be silenced with a macro like this one:

#ifdef UNUSED
#elif defined(__GNUC__)
# define UNUSED(x) UNUSED_ ## x __attribute__((unused))
#elif defined(__LCLINT__)
# define UNUSED(x) /*@unused@*/ x
#else
# define UNUSED(x) x
#endif

The question is: where to place this file? Inside include or util directory? What name? opencog_defs.h?
Also, I see no version definition in the headers. It may be named opencog_defs.h.in, with CMake generating the file with proper version as defined in main CMakeLists.txt (if there is some value in defining the version).

While attempting to adapt to doxygen changes between versions I introduced another problem:
The modified CMake file used VERSION_GREATER to check the version. It looks like the CMake version has no VERSION_GREATER, as the build bot produces following warning:

CMake Warning at CMakeLists.txt:683 (IF): given arguments: "VERSION_GREATER" "1.8.1" Unknown arguments specified

The reason for the initial change was:

• to add a custom css to enhance the look of the documentation
• to add custom header & footer to allow adding opencog banner (not implemented), etc, to better integrate in opencog site

Right now, the easiest solution that I can think of (doesn't involve changing the requirements for doxygen or cmake version) is to drop the custom header/footer and ignore doxygen guidance to use HTML_EXTRA_STYLESHEET.

An alternative solution would be to add a version check macro for CMake in lib directory, but I suspect that would help only with css; older doxygen may not support tags like $navpath.

When ever I try to compile OpenCog under Guile 2.0 I get errors such as cannot find libguile.h and when I attempt to work around these errors by manually entering the path to libguile.h in the C files in OpenCog I get errors like:

I am making the switch from Guile 1.8 (which compiles fine) to Guile 2.0 (which doesn't compile) because I was getting stack overflow errors when I used OpenCog compiled with Guile 1.8

Is their a way to either compile OpenCog under Guile 2.0 or make it so that Guile 1.8 does not give stack overflow errors.

Thank you.

cmake produces this output:

-- Cxxtest was not found. Make sure CXXTEST_BIN_DIR is set.

The cxxtestgen executable is in /usr/bin, so I tried

CXXTEST_BIN_DIR=/usr/bin/ cmake ..

and got the same result.

The following fails:

moses -nexp -H cp -y "+(-1 impulse(\$1))"

by contrast, the nearly identical

moses -H cp -y "+(1 impulse(\$1))"

succeeds almost immediately. Maybe there is a problem exploring negative contins?

After pull request #290, listUTest began throwing an exception.
BuildBot: Test # 73: listUTest ***Exception: Other

From LastTest.log:
unrecognized expression a

The pattern matcher can call any given program or function, including functions written in python. However, the python bindings to opencog are incomplete and non functional.

The place where things need to fixed is here: line 225 and onwards, in /opencog/query/PatternMatcher.cc

The goal here is to call the named python routine, pass it the N different supplied Handles, and get back a return Handle. In principle, PyRun_SimpleString() should be enough, except that it crashes :-(

Refactoring AtomSpace.print_list() so it outputs in form of Scheme

IndefiniteTruthValueUTest and iostream_bscored_combo_treeUTest were failing on my system, so I launched a new 12.04.2 VM and used ocpkg to setup the environment. I confirmed that in this fresh environment, they are also failing.

They are currently passing on BuildBot. I am wondering if anyone has any ideas on what is different in the configuration settings of BuildBot from a fresh ocpkg environment?

I included the output from LastTest.log below.

Hello all,

I'm trying the examples on the wiki page (http://wiki.opencog.org/w/MOSES_Tutorial), but I'm getting quite different output from what the wiki page suggests. Based on a fresh pull (1 hour old) of the source code from git.

The wiki page says that if you enter

moses -Hmux -k3

It should come back with

-0 or(and(!#1 #2) and(#1 #3))

However I get:

-304 or(and(or(and(or($2 $9) $1 $3 $11) and(!$1 !$3) and($1 $2 $7) and(!$2 $5)) or(and(!$1 !$7 $8) and(!$2 $9) !$3 $11) or(and($3 $8) $1 $6)) and(!$1 $3 $10))

Figured it might have something to do with running it without doing 'make install' first, so I did that (and ldconfig), switched to my home folder (~) and then it came back with:

Please let me know if I'm doing something wrong or if it should become a bug report.

Take care,

In order to create test scenarios where MOSES is used for reinforcement learning for procedure evolution for controlling an agent in the Unity embodiment world, the discrete knobs in MOSES need to support "action" subtrees.

As discussed in a conference call with Nil & Ben, this will require some additions to the current code.

The reason is that in this prior commit, a new version of get_candidate was implemented:
34391b5

And, in knobs.h, the structs:
action_subtree_knob
simple_action_subtree_knob

didn't have this method implemented yet:
append_to

https://github.com/opencog/opencog/blob/master/opencog/learning/moses/representation/knobs.h#L454
https://github.com/opencog/opencog/blob/master/opencog/learning/moses/representation/knobs.h#L519

Therefore, MOSES is currently not able to solve problems where the representation types are actions, as defined on page 8 of 'MOSES-QuickGuide.pdf':
http://wiki.opencog.org/wikihome/images/4/4a/MOSES-QuickGuide.pdf

The 'moses-ant-hillclimbing' example program can be used as a test case for issue resolution.

Alex van der Peet to opencog

Hello all,

I’ve been redoing the setup process for OpenCog in the wiki today to update it to Ubuntu 12.04. It appears the new atom_types.h generation process is not quite perfect yet.

I've loaded some mind agents from a python package using "loadpy" command of cogserver and started them using "agents-start". They got activated successfully but they wont get deactivated using "agents-stop", although cogserver sent "Agents stopped successfully".

The cogserver has a "loadmodule" and "unloadmodule" command. A "listmodules" command is needed, to list the currently loaded modules.

Hello -- I followed the build instructions at

http://wiki.opencog.org/w/Building_OpenCog_on_Mac_OS_X 

successfully and to the letter, then went to

http://wiki.opencog.org/w/MOSES_Tutorial

successfully did

sudo make install

but

sudo ldconfig

said

ldconfig: command not found

finally, i tried

moses

and

moses -Hmux -k3

and got the following, in both cases

make: *** [test] Error 2

This appears even after creating the symbolic links to support the new folder structure.

The error seems similar to the one described here:
https://groups.google.com/forum/#!msg/opencog/JvkTP5et3_A/F_x83Sg-e_wJ

Except I am also getting tests 53 and 99 failing.

Any idea if I am doing something wrong or how I can fix them. Ideally I would like a fully working environment before I start attempting further tutorials.

Thanks,
Graeme

Seriously, guys, C/++ is not the right tool for the job of developing a web app against the cogserver. For that matter, it's probably the wrong tool for developing Controllers and Views, too.

On Ubuntu 12.10, to successfuly build I had to do this, which is not mentioned in the README :

sudo apt-get install libboost-all-dev

which corresponds to Boost libraries.
So, altogether the dependencies gathering step was :

sudo add-apt-repository https://launchpad.net/~opencog-dev/+archive/ppa
sudo apt-get install libboost-all-dev cmake guile-1.8-dev libgsl0-dev libcurl4-gnutls-dev libexpat1-dev libsdl1.2-dev libsdl-gfx1.2-dev unixodbc-dev libxerces-c2-dev libxmlrpc-c-dev

But there are problems further down the road:

~/src/w/opencog/bin/ % make test
[ 2%] Built target smob
[ 2%] Built target opencog_atom_types
[ 6%] Built target util

make[1]: *** [CMakeFiles/test.dir/rule] Erreur 2
make: *** [test] Erreur 2

It appears that /usr/bin/cxxtestgen.py is replaced by:
/usr/bin/cxxtestgen

in cxxtest package as provided by the opencog ppa; indeed:

% ls -l /usr/bin/cxxtest*
lrwxrwxrwx 1 root root 27 juin 18 05:09 /usr/bin/cxxtestgen -> ../share/cxxtest/cxxtestgen

A simple workaround is (as there are references to cxxtestgen.py in many places ) :
sudo ln -s /usr/bin/cxxtestgen /usr/bin/cxxtestgen.py

Final result:
95% tests passed, 5 tests failed out of 93

Total Test time (real) = 154.76 sec

The following tests FAILED:

55 - MathUTest (Failed)
60 - RESTfulTest (Failed)
72 - procedure_repositoryUTest (Failed)
92 - feature_selectionUTest (Failed)
Errors while running CTest

Now I'm blocked, given the README instructions: I can't start the server or the interactive shell :

The iris dataset opencog/learning/moses/example-data/iris.data doesn't work any more:

returns

The moses log file explains more:

I guess we need a unit test for this ...

I tried with link-grammar 4.7.8 and 4.7.11, but neither seems to install read-dict.h.

In file opencog/embodiment/Control/PerceptionActionInterface/PAI.cc, around line 1119,
if strlen(targetType) is 0 targetTypeCode will have an undefined value;

I seek guidance as I don't understand the structure of the code, yet. So I should:

• initialise targetTypeCode to a default value if targetType has a real chance of being empty
• or convert the if (strlen(targetType)) line into an assert if it's very unlikely to be empty ?

Even though I've cloned the repo from github, the cmake scripts contain some
bazaar references and dependencies:

Fresh pull from < 1 hour ago. First an atom_types.h error:

Then I go into build/opencog/atomspace, do make there, so I have my .h file now. Then I go back to /build to do make, and it fails on some Cython / Python stuff.

/home/alex/ocfresh/opencog/reasoning/pln/Testing.cc:16:46: fatal error: opencog/cython/logic_wrapper_api.h: No such file or directory

make: *** [all] Error 2.

I have the /build/opencog/cython/logic_wrapper_api.h in my OTHER OpenCog folder tree, I'm guessing this is another one of those files that gets generated during build.

The logic_wrapper_api.h shows up in /cython/CMakeLists.txt but also in /reasoning/pln/Testing.cc. Since this is what it's building before the error, I guess there's a dependency missing here?

I added a dependency from pln to cython in the CMakeLists.txt in /opencog/reasoning/pln, but that didn't fix it.

I'll keep looking at it, see what I can learn from fixing it, but it's dinner time first.

I just followed the wiki on how to build on OSX and got an error :

While testing the forward chainer in the new PLN, I noticed that at each step, the AtomSpace is accumulating many new VariableNodes and links between them.

Can't these be cleaned up after they are bound? Alternately, I noticed that Ari Heljakka suggested previously on the mailing list that these be stored in a "virtual atom repository".

For example, AtomSpace contents before forward inference:

node[ConceptNode:animal]
node[ConceptNode:bird]
node[ConceptNode:swan]
[InheritanceLink <swan,bird> 0.5 0.00062461] 
[InheritanceLink <bird,animal> 0.5 0.00062461] 

AtomSpace contents after one forward inference step:

node[ConceptNode:animal]
node[ConceptNode:bird]
node[ConceptNode:swan]
node[VariableNode:$pln_var_1000004]
node[VariableNode:$pln_var_1000005]

There are query parameters that are defined for the GetListRequest method of the web interface that are not working properly.

GetListRequest filter by handle set query parameter is not working:
This fails: http://localhost:17034/opencog/list?handle=1
This succeeds: http://localhost:17034/opencog/atom?handle=1

GetListRequest filter by type is not working if type is a query parameter; it only works if type is a path segment:
This fails: http://localhost:17034/opencog/list?type=ConceptNode
This succeeds: http://localhost:17034/opencog/list/ConceptNode

First attempt at compiling since the switch to github. Looks like an ugly namespace clash.

In the new PLN, in some cases, the chainer is failing AssertionError during application of the DeductionRule at this assert using the template containing two InheritanceLinks and three associated VariableNodes, where the second search for a template match fails.

Instead of failing hard, shouldn't it just give up for one inference step and allow itself to log the failed inference step?

For example, given an initial AtomSpace:

bird
swan
animal
Inh swan bird 
Inh bird animal 

It fails here:

*** Running ForwardChainer:
Matched template [InheritanceLink <$pln_var_1000004,$pln_var_1000005> 0.0 0.0] with atom [InheritanceLink <bird,animal> 0.5 0.00062461]

opencog/python/pln/chainers.py
line 221, in _find_inputs_recursive
    assert(atom != None)
AssertionError

Whereas it succeeds, given this initial choice:

*** Running ForwardChainer:

Expected:
Start a freshly built cogserver instance, with NLP and atomspaceextensions modules
GET http://localhost:17034/rest/0.2/list?type=ConceptNode
should return

{ "complete":false,
"skipped":0,
"total":9,
"result": [ ...snip... ]
}

...where 'result' is an array of all atoms with type ConceptNode.

Actual:
It returns

{ "complete":false,
"skipped":0,
"total":56,
"result": [ ...snip... ]
}

...where the results are all atoms in the Atomspace.
Note that /list/ConceptNode behaves as expected.

It has come to light that 'shared___cast' names have been REMOVED from boost 1.53 in favor of '__pointer_cast.' Therefore, sources (such as nmxmlparser) containing the former casts will fail to compile when using boost 1.53. Appropriate correction required...

Expected:
with a freshly built cogserver, error messages to a JSON request should always be in JSON format.
Actual:
it is possible to receive untagged, pure-text responses to JSON requests with casual use, and a brief code survey turns up multiple execution paths that need patching to behave correctly.

Compiler warnings are useful but sometimes need to be ignored; as part of my initiation in mysteries of opencog source I plan to remove some of these, so that real problems may be spotted.

Warnings classes:

• uninitialized variables
• unused results
• unused (sometimes set) variable
• strict-aliasing in cython
• sign-compare
• enum values not used in switch
• parentheses suggested
• order of initialization in constructor
• no return statement in function returning non-void
• deprecated auto_ptr

MathUTest pass/fail seems to depend on some very subtle float-point rounding issues; a minor change in rounding causes the test to blow up. I debugged a little and here's what I found:

rectangles are added and removed from SuperEntity, and then the overall geometry is recomputed in SuperEntity::rebuild() This uses the function rectangle.isInside() repeatedly to test if geometries intersect.

The problem seems to be that the geometries neither intersect, nor don't intersect: they just touch. So the tiniest shift in geometry, a change in the last bit of a floating-pint number, will cause the Rectangle::isInside() to go from true to false. This changes how SuperEntity::rebuild() responds, and thus, causes MathUTest to bomb out.

Figuring out how to fix this will require understanding what SuperEntity is and what it does ...
