presumably, your cmake version is different than ours.  --linas

Hello,

There is some error about missing atom_type dependency at the very end. Did you install atomspace?

Could you paste the errors in the post itself from next time?

Yours sincerely

Hello,

yes i installed atomspace and all its requirements, i will try to reinstall it to see if that helps.

i will try to paste the errors directly on the post next time.

Yours sincerely

This may not be the best idea, but can you try running cmake with -Wno-dev option? It appears that it would suppress most of the warnings. I know it feels like sweeping the troubles under the rug, but see if you can get it compiled.

Ahh, OK, that is a newer version of cmake than what is in trusty. 

I think I may have fixed this in 

https://github.com/opencog/atomspace/pull/841

https://github.com/opencog/opencog/pull/2327

I think that will fix it for you, but also, I suspect opencog works only in trusty, so you are likely to hit additional bugs.

Hello,
  

    after i merged the fixes on the cmakefiles, i tried building it again to no avail then i tried rebuilding atomspace and hit a couple of warnings:


warnings from cmake ..:

CMake Warning at tests/persist/sql/odbc/CMakeLists.txt:67 (MESSAGE):
  /usr/bin/psql: psql: FATAL: Peer authentication failed for user
  "opencog_tester"



CMake Warning at tests/persist/sql/odbc/CMakeLists.txt:82 (MESSAGE):

..

CMake Warning (dev) in CMakeLists.txt:
  No cmake_minimum_required command is present.  A line of code such as

    cmake_minimum_required(VERSION 3.5)

  should be added at the top of the file.  The version specified may be lower
  if you wish to support older CMake versions for this project.  For more
  information run "cmake --help-policy CMP0000".
This warning is for project developers.  Use -Wno-dev to suppress it.

-- Configuring done
CMake Warning (dev) at opencog/atoms/base/CMakeLists.txt:13 (ADD_LIBRARY):
  Policy CMP0003 should be set before this line.  Add code such as

    if(COMMAND cmake_policy)
      cmake_policy(SET CMP0003 NEW)
    endif(COMMAND cmake_policy)

  as early as possible but after the most recent call to
  cmake_minimum_required or cmake_policy(VERSION).  This warning appears
  because target "atombase" links to some libraries for which the linker must
  search:

    pthread, pthread

  and other libraries with known full path:

    /home/kefeh/atomspace/build/opencog/truthvalue/libtruthvalue.so
    /usr/local/lib/libcogutil.so

  CMake is adding directories in the second list to the linker search path in
  case they are needed to find libraries from the first list (for backwards
  compatibility with CMake 2.4).  Set policy CMP0003 to OLD or NEW to enable
  or disable this behavior explicitly.  Run "cmake --help-policy CMP0003" for
  more information.

Check your merge:

https://github.com/opencog/atomspace/blob/master/CMakeLists.txt#L15

that line has been there forever.  So have the cmake policy lines below it.

ah, yes. You will need to pull and buld a new version of cogutils to fix this. This is a very recent change.  Typically, changes like this are not made very often, but it was needed, in this case.  

Don't forget to rebuild the atomspace after doing cogutils

Hello,

Sadly, this is currently the "normal" situation. We've got a problem with python sending its output to the wrong place; this needs to be fixed.  The rest snow-ball from there.

Hello,

    i am curious to know if without my Opencog built properly can i start contributing or working on a bug? if i can, can someone point(and guide me through) to a beginners bug so i can get started? i am still new to Open Source.

Thanks

Kefeh,

As you know, the primary code is on github. It's a fantastic platform for making forks (copies of code that you can modify into your own version). If your version fixes a bug that we want to merge back into the main code, you can submit a pull request to try and get it written into the main code "branch." Even if your pull request is denied, your fork is still available to you and anyone else to use. (However, it will not receive updates automatically when the main code gets patched. You have to manually repull from the main branch to your branch to keep your branch current.)

There a much better write-ups on how github works? by that is the super short of it.

Tl:dr: Make a fork. If you fix a bug, submit a pull request, otherwise have fun!
