problem with start-up of srsRAN4G

[FirstRSSO]

Hi everyone,

I've been following this tutorial on setting up a 4G LTE network with LimeSDR: (https://www.quantulum.co.uk/blog/private-lte-with-limesdr-and-srsran--part-4-config--launch/.)

Unfortunately, I've encountered an issue while setting up the eNodeB (eNB). The error I’m getting is as follows:root@srsRAN:/home/srsran# sudo LD_LIBRARY_PATH=${SRSRAN_INSTALL}/lib sh -c "cd ${HOME}/.config/srsran; ${SRSRAN_INSTALL}/bin/srsenb enb.conf"

It looks like you do not have the LimeSDR driver installed correctly.

See this line from the console output: "Supported RF device list: UHD file". It should list lime here too.

Make sure it is installed correctly and then re-build srsRAN.
