Hi ...
If you run GRC on the E310 with:
LD_PRELOAD="/usr/lib/libQtDeclarative.so.4.8.6 /usr/lib/libQtSvg.so.4.8.6
/usr/lib/libQtXml.so.4.8.6 /usr/lib/libQtWebKit.so.4.9.4" gnuradio-companion
You are able to get to the point where the problem is an unavailablity of
PYQty4.Qwt5 as Qwt
ImportError: no module named Qwt5 ....
As we speak I am trying to examine if I can cross compile The missing
module and install it on the target device to get things to proceed further.
Thanks for your interest.
