Re: [Discuss-gnuradio] New build structure! (Warning #2)

[Daniel Dekst]

Thanks, no further error.

'make check' returns no rule to make check, but we can 'make install' without error.

A problem is that the PYTHONPATH is not set, so we get error 'cannot find gnuradio' when we are trying to run an example.
Even though I put
export PYTHONPATH=/usr/local/lib/python2.6/site-packages
in ~/.bashrc and ~/.profile
it does not work.
I have to type
export PYTHONPATH=/usr/local/lib/python2.6/site-packages
in each terminal that I log into the E100 through SSH.
Is there a way to set PYTHONPATH permanently on E100?

You may want to experiment with compiler flags. Try this:

cmake -DCMAKE_CXX_FLAGS:STRING="-mcpu=cortex-a8 -mfpu=neon
-mfloat-abi=softfp -g" -DCMAKE_C_FLAGS:STRING="-mcpu=cortex-a8
-mfpu=neon -mfloat-abi=softfp -g" <gr_source_dir>
