Developer-Guide

This project implements a real time platform to deploy the O-CU and O-DU and it’s based on Yocto/OpenEmbedded.

This includes a Yocto/OpenEmbedded compatible layer meta-stx-oran and wrapper scripts to pull all required Yocto/OE layers to build out the reference platform.

To contribute on this project, basic knowledge of Yocto/OpenEmbedded is needed, please refer to the following docs if you want to learn about how to develop with Yocto/OpenEmbedded:

1. Prerequisite for build environment

The recommended and tested host is Ubuntu 16.04/18.04 and CentOS 7.

  • To install the required packages for Ubuntu 16.04/18.04:

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
  build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
  xz-utils debianutils iputils-ping make xsltproc docbook-utils fop dblatex xmlto \
  python-git

  • To install the required packages for CentOS 7:

$ sudo yum install -y epel-release
$ sudo yum makecache
$ sudo yum install gawk make wget tar bzip2 gzip python unzip perl patch \
  diffutils diffstat git cpp gcc gcc-c++ glibc-devel texinfo chrpath socat \
  perl-Data-Dumper perl-Text-ParseWords perl-Thread-Queue perl-Digest-SHA \
  python34-pip xz which SDL-devel xterm

2. Use wrapper script build_inf.sh to setup build env and build the INF AIO x86 image

# Get the wrapper script with either curl or wget
$ curl -o build_inf.sh 'https://gerrit.o-ran-sc.org/r/gitweb?p=pti/rtp.git;a=blob_plain;f=scripts/build_inf.sh;hb=HEAD'
$ wget -O build_inf.sh 'https://gerrit.o-ran-sc.org/r/gitweb?p=pti/rtp.git;a=blob_plain;f=scripts/build_inf.sh;hb=HEAD'

$ chmod +x build_inf.sh
$ WORKSPACE=/path/to/workspace
$ ./build_inf.sh -w ${WORKSPACE}

If all go well, you will get the ISO image in: ${WORKSPACE}/prj_oran_inf_anaconda/tmp-glibc/deploy/images/intel-corei7-64/inf-image-aio-installer-intel-corei7-64.iso
