Re: [Discuss-gnuradio] Tests of gr-analog failed

I did a fresh rebuild. But it does not work.

/home/schroer/gnuradiocomponents/gnuradio/build-3.7.2/gr-analog/python/analog/qa_agc_test.sh
Traceback (most recent call last):

ImportError:
/home/schroer/gnuradiocomponents/gnuradio/build-3.7.2/gr-analog/lib/libgnuradio-analog-3.7.2git.so.0.0.0:
undefined symbol: volk_32f_invsqrt_32f_a


This is due to wrong setting of the LD_LIBRARY_PATH in the
qa_agc_test.sh file.
It is set :

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH

which points to an existing ( older ) gnuradio installation. But I don't
want the existing gnuradio but the new one that lives in the build
directory.

Setting

export
LD_LIBRARY_PATH=/home/schroer/gnuradiocomponents/gnuradio/build-3.7.2/volk/lib:$LD_LIBRARY_PATH

in qa_agc_test.sh

makes the test work.

So the only thing todo is to find the place where this variable will be
constructed for use in the test files.
