Issue in installing ICC from intel oneapi basetoolkit issue with license file

Question

We are trying to build ORAN- ODU-Low library ( https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/build_prerequisite.html ).

We have downloaded and built DPDK ,

#wget http://static.dpdk.org/rel/dpdk-18.08.tar.x
#tar -xf dpdk-18.08.tar.xz
#export RTE_TARGET=x86_64-native-linuxapp-icc
#export RTE_SDK=Intallation_DIR/dpdk-18.08

build DPDK:

#./usertools/dpdk-setup.sh
select [39] x86_64-native-linuxapp-icc
exit [62] Exit Script
'''

DPDK built successfully.

While building fapi library from odu, we see below errors:

We are building it on CentOS 7 - 3.10.0-1160.45.1.el7.x86_64 gcc version used: 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)

Intel compiler icc was previously available as a part of intel system studio and required a license. The documentation on installing icc you refer seems to on O-RAN docs seems to be written during this period. Intel system studio now has been replaced by Intel oneAPI toolkits

Currently intel compilers(eg icc) are available for free without any license as a part of intel oneAPI HPC toolkit. You could easily download the toolkit for free by visiting the below link, and start using icc without issues.

If you still need to download the older versions of icc you could try out by visiting the below link.
