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-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:

Processes

1. Prerequisite for build environment

$ 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_oran.sh to setup build env and build the image

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

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

If all go well, you will get the ISO image in: ${WORKSPACE}/prj_wrl1018_oran/tmp-glibc/deploy/images/intel-x86-64/oran-image-inf-host-intel-x86-64.iso
