linuxubuntubug锦集（⼀）
⼀、liunx下安装软件报错requiers compiler and library support for iso&n
requiers compiler and library support for iso c 2011 standar
error: this support must be enabled with the -std=c 11 or -st
⽤下⾯的命令检查你的g ++编译器的版本：
⼆、centos7 ⽆法在线播放⾳乐
需要下载adobeflash 下载完后rpm 安装就⾏
2.如果mp3⽆法播放，按着提⽰安装软件即可
三、vmware上的linux 可以ping通windows，但是windowsping不同linux，并且也不再⼀个⽹段
1.这时候是因为你⽤的nat模式，只需要重新改⼀下桥接模式就⾏，这样本机windows和VMware上linux就在同⼀个⽹段了，⽽且可以互相ping
三、ubuntu14没有外接⾳箱没有声⾳（只有在设置⾥点击模拟输出⾳频的时候才能有声⾳）
转载
四  ubuntu14上⾃带的输⼊发有问题，输⼊汉字不准确
解决办法：
这时候 我们回到桌⾯ 按“ctrl”+“Alt”+“T”，打开系统终端，在终端⾥⾯输⼊ibus-daemon -drx并回车
五。ubuntu14挂在硬盘报错：
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
解决：django无跳转操作mysql增删改查
下⾯是⽤parted⼯具对/dev/sda做GPT分区的过程：centos和ubuntu
