在12.04上安装gcc4.7时，GCC不会从4.6切换到4.7 [英] When installing gcc4.7 on 12.04, GCC doesn't switch from 4.6 to 4.7

问题描述

我目前安装了gcc4.7和gcc4.7-base等软件包，但当我调用

<$ p $时，GCC似乎仍然在使用4.6 p> gcc --version


如果我真的可以编译源代码现在需要它，但我打算将一些旧代码转换为使用C ++ 11来获得乐趣。如果任何人有任何关于如何从4.6切换到4.7的建议，请告诉。

我遵循以下指南：

编辑：修正了这个问题，更新了/usr/bin/gcc-4.7的链接

解决方案

尝试运行以下命令以查看gcc的位置：

  ls -l`which gcc `
  

我想说你可能需要做的几率是更新链接再次我不能检查，因为我目前没有启动到Linux）

I currently have the gcc4.7 and the gcc4.7-base, etc., packages installed but GCC seems to still be using 4.6 when I call

gcc --version

I could compile the source code if I really needed it now, but I plan on converting some old code to have fun with C++11. If anyone has any suggestions on how to switch from 4.6 to 4.7 do tell.

I followed the guide from here :

Edit: Fixed the issue, updated link to /usr/bin/gcc-4.7

解决方案

Try running the following to see where gcc is located:

ls -l `which gcc`

I'd say that odds are all you may need to do is update the link (but then again I can't check as I'm not booted into Linux at the moment)
