Hi,

I’m want to use grcc from an ssh session but I get the error importing  
the  
module Colors.py.  
I’ve seen this thread  
[http://lists.gnu.org/archive/html/discuss-gnuradio/2013-06/msg00361.html](http://lists.gnu.org/archive/html/discuss-gnuradio/2013-06/msg00361.html)  
about it. I’m using 3.7.5 and it seems like the patch it’s been applied  
to  
the source code already. There are no differences between what the patch  
suggests and the source code that the installer script downloaded to my  
machine. However, I still get the import error (only when I use ssh).

Thanks,  
Murray

I tried to reproduce this on the current master. I also get “Unable to  
import Colors”, but it is not an exception.  
grcc still completes and the output file is generated.

Thanks Sebastian,

“Unable to import Colors” is also a warning for me, but then I also get:

Unable to import Colors  
‘module’ object has no attribute ‘CONNECTION\_ENABLED\_COLOR’  
Error during file compilation.  
make: \*\*\* [grc\_rx] Error 1

Which is an error. It looks like my flowgraph needs Colors after all but  
I  
don’t know why because it doesn’t have a GUI.

Thanks,  
Murray

Problem found. I pushed a fix to the maint\_grc branch on the grcwg repo:

[https://github.com/gnuradio/gnuradio-wg-grc/commit/b57a4cbe8229635a1a2c87ff70f7842f74def72a](https://github.com/gnuradio/gnuradio-wg-grc/commit/b57a4cbe8229635a1a2c87ff70f7842f74def72a)

Let me know if that works for you.
