构建RISC-V GNU工具链-推荐的Linux虚拟机配置？

Question

我尝试过几次，但都失败了，无法将riscv-gnu-toolchain安装到虚拟机中。是否有人建议使用Linux /虚拟机配置（最好是Vagrantfile）？如果找不到，我将自己做一个并在这里分享。起始操作系统版本，内存和硬盘驱动器容量-理想情况下为非GUI，并且在合理的范围内应尽量减小。

而且，由于它的构建如此庞大，人们是否对多CPU设置和make -j6（或您的核心数量）进行并行构建感到幸运？

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/xenial64"
  # needs vagrant plugin install vagrant-disksize:
  config.disksize.size = '40GB'
  config.vm.provider "virtualbox" do |v|
    v.linked_clone = true
    v.cpus = 12
    v.memory = 8192
    v.name = "RISC-V Toolchain (Ubuntu 16)"
  end
  config.vm.provision "shell", inline: <<-SHELL
    echo "updating apt"
    apt-get update
    echo "installing dependencies"
    apt-get install -y autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev
    mkdir /opt/riscv
    chown vagrant:vagrant /opt/riscv
    cd /home/vagrant
    echo "checking out toolchain"
    export HOME=/home/vagrant
    sudo -u vagrant git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
