Archives in this directory contain static binaries, so any kind of run-time linkage error is not expected. Please let me know if you experience such an error, or any kind of unexpected behaviour. LZMA archives can be extracted as follows, tar xvfa SCOREF-MGMT-v1.0.4.tar.lzma Not for all versions a binary is created when the change is subtle and/or documentation related. So please follow OpenAirInterface SVN for most up-to-date version. Note: Name has changed from IF.MGMT to SCOREF-MGMT from version 1.1.0 on. - Baris Demiray
