ginga seg fault with missing ginga_config #65

Closed pllim closed 9 years ago

pllim commented 9 years ago

In the current master version (2.1.20141220052723) in RHEL 6.6 (Santiago) 64-bit, I get segmentation fault and the traceback complains of a missing ginga_config. I checked out the source from GitHub and installed it with python setup.py install --prefix=LOCAL_DIR command. Am I missing something?

Can you try running it with --loglevel=10 --log=/tmp/ginga.log

and force the toolkit with -t qt (use qt) or -t gtk (use gtk) (but not both at the same time)

Please attach the last 20 lines of the log in this issue.

We're running it on several 64-bit RHEL machines no problem. I'll have to check the version--might be 6.5.

pllim commented 9 years ago

Update: I modified my copy of ginga script to force loading QtHelp first, and then again, I am getting missing ginga_config error as per my original post. I cannot find any ginga_config.py in your code repository.

ejeschke commented 9 years ago

@plim, don't worry about the ginga_config.py error--that is normal if you have not created one in your ~/.ginga directory. It is used to customize ginga. That error by itself should not keep ginga from starting.

If you are still having issues getting the ginga window to appear, can you try one of the much simpler example programs first? Try running

python examples/qt/example2_qt.py

or

python examples/gtk/example2_gtk.py

These can also be run with the logging options. Please let me know the outcome.

pllim commented 9 years ago

python .../example2_qt.py works. Hmmm!

pllim commented 9 years ago

So, #67 fixes my problem mostly. A GUI pops up now. Occasionally, when I call it again after I close the GUI, I still get seg fault but the GUI will work again after I try to call it yet again. When the GUI does pop up, I see this warning on the terminal:

No handlers could be found for logger "ImageViewBase"
ejeschke commented 9 years ago

@pllim, I just checked our machines. They are "Red Hat Enterprise Linux Server release 6.6 (Santiago) ". We are using both qt and gtk versions. No issues that I know of.

What Qt versions do you check against? (I am not interested in the GTK interface at the moment.)

Does this help? What version of astropy are you using?

pllim commented 9 years ago

I use the dev version of astropy. Here is my version info. I use PySide, not PtQt4.

I think we have to re-open this. #67 does not work anymore and I don't think it's the real fix; which means it will have to be reverted. I managed to get a bit more info on the seg fault, as follows.

(Update: I added more traceback)

I am starting to believe that this is something I have to fix on my end and has nothing to do with ginga itself... :o)

ejeschke commented 9 years ago

@pllim, any way you can test against PyQt4 instead of PySide? They've both worked well in my testing, but I have to say that I've only tested PySide with ginga under Ubuntu 14.04, although I have heard from others using it fine on other platforms.

pllim commented 9 years ago

I tested it with Anaconda instead of Ureka, and it worked. I'll update you if I find out more.

ejeschke commented 9 years ago

Excellent. That's our usual installation advice for mac and windows users--use anaconda or canopy. It would be very nice to get this working with Ureka, so let me know if you figure out anything. Tnx!

ejeschke commented 9 years ago

Going to close this, as it seems to not actually involve ginga.
