21/04/22 #005 (free5gc) Install Go Language Package On Ubuntu 18.04 (5.0.0-23-generic)

Installation

1. Linux Kernel Version

   • In order to use the UPF element, you must use the 5.0.0-23-generic version of the Linux kernel. free5gc uses the gtp5g kernel module, which has been tested and compiled against that kernel version only. To determine the version of the Linux kernel you are using:

       $ uname -r
       5.0.0-23-generic

2. Golang Version

   • As noted above, free5gc is built and tested with Go 1.14.4

   • To check the version of Go on your system, from a command prompt:

       go version

   • If another version of Go is installed, remove the existing version and install Go 1.14.4:

       # this assumes your current version of Go is in the default location
       sudo rm -rf /usr/local/go
       wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
       sudo tar -C /usr/local -zxvf go1.14.4.linux-amd64.tar.gz

   • If Go is not installed on your system:

       wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
       sudo tar -C /usr/local -zxvf go1.14.4.linux-amd64.tar.gz
       mkdir -p ~/go/{bin,pkg,src}
       # The following assume that your shell is bash
       echo 'export GOPATH=$HOME/go' >> ~/.bashrc
       echo 'export GOROOT=/usr/local/go' >> ~/.bashrc
       echo 'export PATH=$PATH:$GOPATH/bin:$GOROOT/bin' >> ~/.bashrc
       echo 'export GO111MODULE=auto' >> ~/.bashrc
       source ~/.bashrc
