Fatal Python error: PyThreadState_Get: no current thread (Mountain Lion)

[c1de0x]

On Mountain Lion, I'm getting:

$ gnuradio-companion
/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gtk-2.0/gtk/init.py:57: GtkWarning: could not open display
warnings.warn(str(e), _gtk.Warning)
Fatal Python error: PyThreadState_Get: no current thread

Possibly a lib-path error?

$ DYLD_PRINT_LIBRARIES=1 gnuradio-companion 2>&1 | grep -i python | grep -v Cellar
dyld: loaded: /usr/local/bin/python
dyld: loaded: /System/Library/Frameworks/Python.framework/Versions/2.7/Python
Fatal Python error: PyThreadState_Get: no current thread

this is forked from Issue #6

Indicates that it's linking against the system python. I'm looking into how to prevent that.

[titanous]

It looks like this DYLD_FRAMEWORK_PATH is needed: f9655d5

I removed it because of this error message:

dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

I'm looking into how to make it work again.

[titanous]

According to this, that's just a red herring: http://openradar.appspot.com/11894054

I'm trying to compile it with the path set correctly, we'll see how it goes.

[c1de0x]

ok ill test again when you push an update

[titanous]

You can actually test right now by running:

export DYLD_FRAMEWORK_PATH=/usr/local/lib:$DYLD_FRAMEWORK_PATH
brew uninstall gnuradio
brew install gnuradio

[c1de0x]

nope. still borked

I just pushed a patch that fixes this issue. Can you test it out?

brew update
brew uninstall gnuradio
brew install gnuradio

[c1de0x]

Now I get a segfault:
gnuradio-companion/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gtk-2.0/gtk/init.py:57: GtkWarning: could not open display
warnings.warn(str(e), _gtk.Warning)
Segmentation fault: 11

[titanous]

Do you have XQuartz installed?

[c1de0x]

Yes. XQuartz 2.7.2

[GRMrGecko]

From the looks of it, this looks to be an issue where GNURadio is compiling against OSX's python install.

Looking further it seems cairo is causing the crash. Uninstalled everything I installed to manually build GNU Radio with Mac OS X Python and re-installing it.

[GRMrGecko]

brew uninstall cairo py2cairo pygobject pygtk gtk+ gnuradio

brew install pygtk gnuradio

That fixed it for me as I installed the other packages before I installed python via brew..

[lokkju]

I'm still getting this - using a little tool I wrote that tells you which dylibs are using the system python ( https://gist.github.com/4466116 ), I found that /usr/local/lib/python2.7/site-packages/gnuradio/qtgui/_qtgui_swig.so was linked against the System python.

I tried removing both swig and gnuradio and reinstalling - but with no luck.

Ideas?

[zacmanchester]

I had the same problem. I got around it by temporarily symlinking the brewed python in place of the system python, brew uninstall gnuradio, brew install gnuradio, then changing the symlinks back.

I know the issue is closed, but just for reference I've had a simillar issue today. What helped me was following what tomekr did in metacollin/homebrew-gnuradio#47 (comment)
