cannot start Xpresser in fedora

While I did have some issues using it in Fedora, I was at least able to import it. I think you might be missing some dependencies, do you have cairo and gi-cairo installed?

I cannot find gi-cairo in repositories. I will try to install it using pip.

I have installed cairo-gobject from repositories, but problem still remains.

I'm working on this as well but I'm hitting an additional issue with getting xpresser to run on Fedora.

ImportError: No module named opencv

I'm having trouble figuring out where this python module comes from. As far as I can tell, the python bindings from opencv are compiled as the 'cv' module, not 'opencv'. Is another wrapper being used or is this a platform difference between the opencv packages?

I'm not very familiar with bzr and apparently, I was using an old version of the code.

The new version is presenting other issues that seem to be related to platform differences between Ubuntu and Fedora (the v4l dep in pygame for SimpleCV is what I think I'm hitting right now but I'm not 100% sure). I'll keep plugging away at this as I have time.

Chris, do you happen to remember what deps you needed when you tried xpresser on Fedora?

I have tracked down one of the assertions:
in xutils.py you are importing pyatspi and then SimpleCV. If I, on Fedora, try to import SimpleCV, it is OK. If I import pyatspi and THEN SimpleCV, it shows:

/usr/lib64/python2.7/site-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
  import gobject._gobject

And when you import SImpleCV and then pyatspi, it shows traceback:

>>> import SimpleCV
>>> import pyatspi
ERROR:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/pyatspi/__init__.py", line 17, in <module>
    from gi.repository import Atspi
  File "/usr/lib64/python2.7/site-packages/gi/__init__.py", line 23, in <module>
    from ._gi import _API, Repository
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".',))

It seems like Fedora-related issue with SimpleCV. I have tried it on freshly-installed F17 and it worked. So Xpresser is fine, please, close this bug.

I just installed this on ubuntu 12.04 and I am getting the errors first mentioned.

Regarding my above comment.

I realized I was not running unity and had installed the gnome-classic/fallback
So I checked on another computer from a clean install and there were no issues - so it must have just been a library mixup when installing the classic/fallback of gnome.

So, there is no issue with a clean install. - also I was able to get it working on fedora 18 just fine.

Thanks for the feedback Garret and afonit, I am closing this bug
