Amber Status

===12.10.2012=== Full install of mousetrap complete. Config file was manipulated to include failed dependency on 'python-opencv' which has been updated and the package is now referred to as 'cv'. Other dependencies are outdated or the names have been changed as well (xlib-python, etc). New errors with 'gobject' have been identified. Here is the recorded error when running mousetrap:


 ImportError: could not import gobject
 (error was: ImportError('When using gi.repository you must not import static modules like "gobject".
 Please change all occurrences of "import gobject" to "from gi.repository import GObject".',))

Will attempt to remove instances of broken dependency opencv to the newer cv


12.17.2012

Bug for pygobject is here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649861

  • The fix is to upgrade to version 3 of gtk?
  • Changed line in configure.in file to AM_CHECK_PYMOD(cv,,,[AC_MSG_ERROR(Could not find python module cv)]) to fix opencv problem when creating make files
  • Highgui no longer exists in the new API for cv (once known as opencv) and it should just be called as cv.whatever.
  • cvCreateCameraCapture() no longer exists, replaced with cv.CaptureFromCAM().

12.19.2012

  • In this particular file: widgets.py, we actually want to import gobject directly and type_register the Mapper using gobject. After doing this, I have the Window pop up and now a new error has come up.

and this:

 (mousetrap:19550): Gtk-WARNING **: Unable to locate theme engine in module_path: "clearlooks",


I believe this is explained in this reported bug: https://bugs.launchpad.net/bzr-gtk/+bug/923824

  • There is a whole big issue with dependencies surrounding pygobject, pygtk, and gtk that are causing errors.


12.20.2012

Looked into error with pygobject, gtk and pygtk and found that the import gi must be the first import in main.py


1.7.2013

1.9.2013

Looks like there are some inconsistencies with opencv. Going through and removing outdated methods. I was also looking to see how the camera is initiated, reading through code.

1.11.2013

Was able to get rid of the small_img error after trying several adaptations of opencv methods.

  • cvSize no longer exists and the python tuple (int, int) should be used instead.

Have new error:

  • It appears that the error is appearing becuase there is no image being captured from the webcam. I am working on trying to figure out why that is.

  • Noted that mousetrap and gnome-mousetrap are in the Ubuntu repository. Ignoring this and following instructions provided by the MouseTrap GNOME Live! project page…
  • Installation went as expected. Ran into every issue in the 'Troubleshooting' table, but that seems to be expected behavior.
  • Running MouseTrap with command 'mousetrap'. Expected errors due to lack of webcam. Otherwise seems to run without issue (preferences window pops up when button clicked, and so forth).
  • Quits without issue.

Thoughts on Install Process:

  • Noted that it might be nice if they add the commands for the RPM package manager to the instructions.
  • "Troubleshooting" should be a link to the Troubleshooting section for user-friendliness.
  • 'Dependency hell' is tedious. Due to the fact that MouseTrap is in the Ubuntu repositories suggests it might be in others as well. It might be useful to include this fact in the install instructions.
  • Else it might be useful for the autogen.sh shell file to automatically detect if a package is installed (it already does this) and installs them if they are not. This will run into an issue with different package management systems. A different shell file for the popular ones (APT and RPM)?
  • A GUI installer would be the most user-friendly, but that's not the Linux MO.

  • Webcam received and set up. Seems to be recognized OOTB on Ubuntu -- the light goes on when in use, etc.
  • When running Mousetrap, it shows a blank window (most of the time) or a frozen video frame (only seen this once). In the terminal, it repeatedly displays errors similar to this;
Corrupt JPEG data: 1 extraneous bytes before marker 0xd9
  • When running again with webcam unplugged, it runs fine.
