Build Prerequisite¶
This section describes how to install and build the required components needed to build the FHI Library, WLS Library and the 5G FAPI TM modules. For the f release the ICC compiler is optional and support will be discontinued in future releases
Download and Install oneAPI¶
Download and install the Intel® oneAPI Base Toolkit by issuing the following commands from yor Linux Console:
sudo sh ./l_BaseKit_p_2022.2.0.262_offline.sh
Then follow the instructions on the installer. Additional information available from
Install ICC and System Studio¶
Intel® C++ Compiler and System Studio v19.0.3 is used for the test application and system integration with L1,available from the following link https://registrationcenter-download.intel.com/akdlm/irc_nas/emb/15322/system_studio_2019_update_3_composer_edition_offline.tar.gz
The Intel® C++ Compiler can be used with a community license generated from the text below save it to a file named license.lic

Then copy license file to the build directory under license.lic
COPY license.lic $BUILD_DIR/license.lic
Note: Use serial number CG7X-J7B6G8WS
You can follow the installation guide from above website to download Intel System Studio and install. Intel® Math Kernel Library, Intel® Integrated Performance Primitives and Intel® C++ Compiler are mandatory components. Here we are using the Linux* Host,Linux* Target and standalone installer as one example, below link might need update based on the website
#wget https://registrationcenter-download.intel.com/akdlm/irc_nas/emb/15322/system_studio_2019_update_3_composer_edition_offline.tar.gz
#cd /opt && mkdir intel && cp $BUILD_DIR/license.lic intel/license.lic
#tar -zxvf $BUILD_DIR/system_studio_2019_update_3_composer_edition_offline.tar.gz
Edit system_studio_2019_update_3_composer_edition_offline/silent.cfg to accept the EULA file as below example:
ACCEPT_EULA=accept
PSET_INSTALL_DIR=opt/intel
ACTIVATION_LICENSE_FILE=/opt/intel/license.lic
ACTIVATION_TYPE=license_file
Silent installation:
#./install.sh -s silent.cfg
- Set env for oneAPI or ICC:
Check for your installation path. The following is an example for ICC.
#source /opt/intel_2019/system_studio_2019/compiler_and_libraries_2019.3.206/linux/bin/iccvars.sh intel64 #export PATH=/opt/intel_2019/system_studio_2019/compiler_and_libraries_2019.3.206/linux/bin/:$PATH
Download and Build DPDK¶
download DPDK:
#wget http://static.dpdk.org/rel/dpdk-20.11.3.tar.x #tar -xf dpdk-20.11.3.tar.xz #export RTE_TARGET=x86_64-native-linuxapp-icc #export RTE_SDK=Intallation_DIR/dpdk-20.11.3patch DPDK for O-RAN FHI lib, this patch is specific for O-RAN FHI to reduce the data transmission latency of Intel NIC. This may not be needed for some NICs, please refer to
O-RAN FHI Lib Introduction -> setup configuration -> A.2 prerequisitesSW FEC was enabled by default, to enable HW FEC with specific accelerator card, you need to get the associated driver and build steps from the accelerator card vendors.
- build DPDK
This release uses DPDK version 20.11.3 so the build procedure for the DPDK is the following
Setup compiler environment
- if [ $oneapi -eq 1 ]; then
export RTE_TARGET=x86_64-native-linuxapp-icx export WIRELESS_SDK_TOOLCHAIN=icx export SDK_BUILD=build-${WIRELESS_SDK_TARGET_ISA}-icc source /opt/intel/oneapi/setvars.sh export PATH=$PATH:/opt/intel/oneapi/compiler/2022.0.1/linux/bin-llvm/ echo “Changing the toolchain to GCC 8.3.1 20190311 (Red Hat 8.3.1-3)” source /opt/rh/devtoolset-8/enable
- else
export RTE_TARGET=x86_64-native-linuxapp-icc export WIRELESS_SDK_TOOLCHAIN=icc export SDK_BUILD=build-${WIRELESS_SDK_TARGET_ISA}-icc source /opt/intel/system_studio_2019/bin/iccvars.sh intel64 -platform linux
fi
The build procedure uses meson and ninja so if not present in your system please install before the next step
Then at the root of the DPDK folder issue:
meson build cd build ninja
- set DPDK path
DPDK path is needed during build and run lib/app:
#export RTE_SDK=Installation_DIR/dpdk-20.11.3 #export DESTDIR=Installation_DIR/dpdk-20.11.3
Install google test¶
- Download google test from https://github.com/google/googletest/releases
Example build and installation commands:
#tar -xvf googletest-release-1.7.0.tar.gz #mv googletest-release-1.7.0 gtest-1.7.0 #export GTEST_DIR=YOUR_DIR/gtest-1.7.0 #export GTEST_ROOT= $GTEST_DIR #cd ${GTEST_DIR} #g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} -pthread -c ${GTEST_DIR}/src/gtest-all.cc #ar -rv libgtest.a gtest-all.o #cd ${GTEST_DIR}/build-aux #cmake ${GTEST_DIR} #make #cd ${GTEST_DIR} #ln -s build-aux/libgtest_main.a libgtest_main.a
- Set the google test Path
this path should be always here when you build and run O-RAN FH lib unit test:
#export DIR_ROOT_GTEST="your google test path"
Configure FEC card¶
For the F Release either a SW FEC, or an FPGA FEC (Vista Creek N3000) or an ASIC FEC (Mount Bryce ACC100) can be used. The procedure to configure the HW based FECs is explained below.
Customize a setup environment shell script¶
Using as an example the provided in the folder phy\setupenv.sh as the starting point customize this script to provide the paths to the tools and libraries that are used building and running the code. You can add for example the following entries based on your particular installation and the following illustration is just an example (use icx for oneApi instead of icc):
- export DIR_ROOT=/home/
- #set the L1 binary root DIR
- export DIR_ROOT_L1_BIN=$DIR_ROOT/FlexRAN
- #set the phy root DIR
- export DIR_ROOT_PHY=$DIR_ROOT/phy
- #set the DPDK root DIR
- #export DIR_ROOT_DPDK=/home/dpdk-20.11.3
- #set the GTEST root DIR
- #export DIR_ROOT_GTEST=/home/gtest/gtest-1.7.0
- export DIR_WIRELESS_TEST_5G=$DIR_ROOT_L1_BIN/testcase
- export DIR_WIRELESS_SDK=$DIR_ROOT_L1_BIN/sdk/build-avx512-icc
- export DIR_WIRELESS_TABLE_5G=$DIR_ROOT_L1_BIN/l1/bin/nr5g/gnb/l1/table
- #source /opt/intel/system_studio_2019/bin/iccvars.sh intel64 -platform linux
- export XRAN_DIR=$DIR_ROOT_PHY/fhi_lib
- export XRAN_LIB_SO=true
- export RTE_TARGET=x86_64-native-linuxapp-icc
- #export RTE_SDK=$DIR_ROOT_DPDK
- #export DESTDIR=""
- #export GTEST_ROOT=$DIR_ROOT_GTEST
- export ORAN_5G_FAPI=true
- export DIR_WIRELESS_WLS=$DIR_ROOT_PHY/wls_lib
- export DEBUG_MODE=true
- export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$DIR_WIRELESS_WLS:$XRAN_DIR/lib/build
- export DIR_WIRELESS=$DIR_ROOT_L1_BIN/l1
- export DIR_WIRELESS_ORAN_5G_FAPI=$DIR_ROOT_PHY/fapi_5g
- export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$DIR_ROOT_L1_BIN/libs/cpa/bin
Then issue:
- source ./setupenv.sh
This sets up the correct environment to build the code
Then build the wls_lib, FHI_Lib, 5G FAPI TM prior to running the code with the steps described in the Run L1 section
