c++: internal compiler error: Killed (program cc1plus) 这个错误通常是因为 memory 不够, 解决方法增加 swap space.

怎么增加 swap space? https://askubuntu.com/questions/178712/how-to-increase-swap-space

1. 创建一个空文件

dd if=/dev/zero of=/media/fasthdd/swapfile.img bs=1024 count=1M

2. Bake swap file:

mkswap /media/fasthdd/swapfile.img

3. 开机时启动:

# 把下面这行加到 /etc/fstab
/media/fasthdd/swapfile.img swap swap sw 0 0

4. 激活:

swapon /media/fasthdd/swapfile.img

验证是否成功:

cat /proc/swaps
  Filename                           Type       Size    Used    Priority
  /media/fasthdd/swapfile.img        file       8388604 2724    -1
