Hi, We just finished installing the following osmo elements using Ubuntu 14.04 and the procedures from this link: https://osmocom.org/projects/cellular-infrastructure/wiki/Ettus_USRP_B2xx_f… https://osmocom.org/projects/cellular-infrastructure/wiki/Build_from_source * libosmocore * libosmo-abis * libosmo-netif * openggsn * libosmo-sccp * openbsc * osmo-pcu * osmo-trx * osmo-bts We are now trying to run each applications to test osmo. All applications were run smoothly except for osmo-trx and osmo-bts-trx. We also installed the UHD driver of Ettus B2xx series using both “apt-get install” process and binary process as well using this link: https://files.ettus.com/manual/page_install.html https://files.ettus.com/manual/page_build_guide.html But still, the same errors were received.
