なに？？？？？？？？？
c++: internal compiler error: Killed (program cc1plus)　はメモリが足りない？？

メモリを増設するか、swap領域を確保するか。
メモリ増設だとvagrant fileか？

  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end

現状を確認します。
swapは0Bか？

で、もう一回、bitconfのディレクトリでmakeします。今度は行けるか？
あれ、もしかして来たか？？
