Re: [Discuss-gnuradio] gr-lte make error

Hi - it worked for me.

I had to run the

python hier_block_install_helper.py

script 3 times to get all the hier blocks - and in order for to ensure
the script completed without any errors.

Using the latest git commit for gr-lte

commit 28b030dd903c4d107fd51e57a28e4c862417e6d1

and I'm running version

3.7.12git-249-g34933ac6

of gnuradio.

The flow graphs

lte_top_block_mimo_2tx.grc
lte_top_block_mimo_4tx.grc

load without any errors but the flowgraph

lte_top_block_siso.grc

has an undefined variable in the disabled

Rational Resampler

block but enabling the disabled variable

interp_val

makes the error the Rational Resampler block disappear.

Look in ~/.grc_gnuradio and see if you see anything there with a prefix of

lte_

Note, I haven't actually used any of the flow graphs.
