Hello everyone, I tried installing the newest release on Ubuntu 20.04, also installed everything needed to pass the "cmake" step, and I got no errors, but when I try to "make" the project I keep getting this error at 95%:

Issue of LTE_fdd_dl_scan with openLTE + bladeRF

In the link: https://sourceforge.net/p/openlte/wiki/Installing%20OpenLTE/

$ mkdir gnuradio
$ cd gnurdio
$ wget http://www.sbrac.org/files/build-gnuradio
$ chmod a+x build-gnuradio
$ ./build-gnuradio -v

But it cannot build successfully.

openLTE has been updated to support gnuradio 3.7, but grextras does not support gnuradio 3.7 and one alternate project named by Pothos is introduced.
So, change EXTRAS=$EXTRAS" https://github.com/guruofquality/grextras.git" to
EXTRAS=$EXTRAS" https://github.com/pothosware/pothos.git" in the file 'build-gnuradio'

It can build successfully and I go on the next process...

Finally, LTE_file_recorder can work with bladeRF.
But LTE_fdd_dl_scan cannot work with baldeRF, Ben said it could work now. What processes might be missed by me?

Below lists my process, thanks for your patience.

open two terminals, A and B
execute orders on terminal A
$ cd openlte_v00-18-04/build/LTE_fdd_dl_scan
$ LTE_fdd_dl_scan
execute orders on terminal B
$ telnet 127.0.0.1 20000
$ start

All messages printed in terminal A are as below:

linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.008.003-137-g2f760ac0

Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.

Error in `LTE_fdd_dl_scan': free(): invalid pointer: 0x00007fde7a66b3f8

The messages printed in terminal B is "Connection closed by foreign host".

"No devices found"? But when run LTE_file_recorder, it can work and can generate a big file for time of seconds.
