Just FYI, trying to compile a controlport client using the embedded  
version of Ice (IceE) gives an error

slice2cppe gnuradio.ice  
gnuradio.ice:72: Struct data member `min' cannot be a value object. gnuradio.ice:73: Struct data member`max’ cannot be a value object.  
gnuradio.ice:74: Struct data member `defaultvalue' cannot be a value object. gnuradio.ice:78: Dictionary`KnobMap’ cannot contain object values.  
gnuradio.ice:87: `KnobMap' is not defined gnuradio.ice:88:`KnobMap’ is not defined

This was on a raspberry pi, where trying to use the regular libice  
gives an “unknown architecture” error, which is weird enough on it’s  
own given that it is a binary package from the raspbian repository.

Alex,

Ok, that’s interesting to see. I don’t know if we’ve ever tried to  
build from IceE before. Hopefully it will be manageable, since we  
would like to have support for it for embedded devices.

Could you post this information on the bug tracker?

Tom

Sounds great.  
I have opened a new item in the bug tracker.
