Tips

Ubuntu 平台 linux 环境下首次编译程序时若遇到：

fatal error: sys/cdefs.h: No such file or directory|

可通过安装 g++-multilib 解决：

sudo apt-get install g++-multilib

用 dlc compiler 时若遇到 dlc: Permission denied 可尝试：

chmod u+x dlc

运行 sudo apt-get update 时若出现

Err http://archive.canonical.com natty InRelease    
Err http://security.ubuntu.com oneiric-security InRelease               
Err http://extras.ubuntu.com natty InRelease                            
Err http://security.ubuntu.com oneiric-security Release.gpg
  Temporary failure resolving ‘security.ubuntu.com’
...

可运行：

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

再重新运行

sudo apt-get update。

若仍遇到问题：

E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/

可尝试：

sudo rm /var/lib/apt/lists/lock

sudo rm /var/lib/dpkg/lock
