Libraries ========= Following libraries are required to compile and execute O-DU High: - GCC - Ubuntu : sudo apt-get install -y build-essential - CentOS : sudo yum groups mark install -y “Development Tools” Ensure the version is 4.6.3 and above using - gcc --version - LKSCTP - Ubuntu : sudo apt-get install -y libsctp-dev - CentOS : sudo yum install -y lksctp-tools-devel - PCAP: - Ubuntu : sudo apt-get install -y libpcap-dev - CentOS : sudo yum install -y libpcap-devel - libxml2 - Ubuntu : sudo apt-get install -y libxml2-dev - CentOS : sudo yum install -y libxml2 Cloning code ============ - Create a folder to clone the O-DU High code into. The folder is hereafter referred to as . - Clone code into git clone "https://gerrit.o-ran-sc.org/r/o-du/l2" Setting up Netconf server (Only if O1 interface enabled) ======================================================== Following steps are required to compile and run ODU with O1 interface enabled. - Create a new netconf user Switch to root user or use sudo and run following commands - Ubuntu : | cd /l2/build/scripts | sudo ./add_netconf_user.sh - Install Netconf libraries: libssh, libyang, libnetconf2, sysrepo, netopeer2 Script is provided in the following folder to install these libraries - Ubuntu : | cd /l2/build/scripts | sudo ./install_lib_O1.sh -c - Install the YANG modules and load initial configuration - Navigate to config folder and update the desired initial configuration | cd /l2/build/config | Open the startup_config.xml and edit the desired IP and Port for CU, DU and RIC. | Open the nacm_config.xml and edit the desired user name to provide the access to that user. | Open the netconf_server_ipv6.xml and edit the desired netconf server configuration. | Open the oamVesConfig.json and edit the details of OAM VES collector. | Open the smoVesConfig.json and edit the details of SMO VES collector. | Open the netconfConfig.json and edit the details of Netopeer server. - Install the yang modules and load initial configuration. - Ubuntu : | $cd /l2/build/scripts | $sudo ./load_yang.sh - Start Netopeer2-server: - Ubuntu : | cd /l2/build/scripts | sudo ./netopeer-server.sh start - In case standard defined VES format is to be enabled (this step is optional): | cd l2/src/o1/ves | Enable the Macro "StdDef" in file VesUtils.h | #define StdDef Compilation =========== - Build O-DU High: - Navigate to Build folder cd /l2/build/odu - Clean O-DU High binary make clean_odu MACHINE=BIT64 MODE=FDD - Compile O-DU High binary make odu MACHINE=BIT64 MODE=FDD - Build CU Stub : - Navigate to Build folder cd /l2/build/odu - Clean CU Stub binary make clean_cu NODE=TEST_STUB MACHINE=BIT64 MODE=FDD - Compile CU Stub binary make cu_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD - Build RIC Stub : - Navigate to Build folder cd /l2/build/odu - Clean RIC Stub binary make clean_ric NODE=TEST_STUB MACHINE=BIT64 MODE=FDD - Compile RIC Stub binary make ric_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD Compilation with O1 interface enabled ===================================== - Build O-DU High: - Navigate to Build folder cd /l2/build/odu - Clean O-DU High binary make clean_odu MACHINE=BIT64 MODE=FDD O1_ENABLE=YES - Compile O-DU High binary make odu MACHINE=BIT64 MODE=FDD O1_ENABLE=YES - Build CU Stub : - Navigate to Build folder cd /l2/build/odu - Clean CU Stub binary make clean_cu NODE=TEST_STUB MACHINE=BIT64 MODE=FDD O1_ENABLE=YES - Compile CU Stub binary make cu_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD O1_ENABLE=YES - Build RIC Stub : - Navigate to Build folder cd /l2/build/odu - Clean RIC Stub binary make clean_ric NODE=TEST_STUB MACHINE=BIT64 MODE=FDD O1_ENABLE=YES - Compile RIC Stub binary make ric_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD O1_ENABLE=YES The above generated images can be found at: - O-DU High - /l2/bin/odu - CU Stub - /l2/bin/cu_stub - RIC Stub - /l2/bin/ric_stub
