在Mint 17.2上安装g ++ 4.9

Question

我正在尝试安装g ++ 4.9或更高版本,以便在Android上构建mapbox.说明指出我需要g ++ 4.9或更高版本.我找到了以下说明,但它们不起作用.

sudo add-apt-repository ppa:ubuntu-toolchain-r/test 
sudo apt-get update
sudo apt-get install g++-4.9

最后一个命令说:

~ $ sudo apt-get install g++-4.9
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package g++-4.9 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'g++-4.9' has no installation candidate

我也尝试从Synaptic Package Manager获得以下内容:

g++:
  Depends: cpp (>=4:4.9-1ubuntu7) but 4:4.8.2-1ubuntu6 is to be installed
  Depends: gcc (>=4:4.9-1ubuntu7) but 4:4.8.2-1ubuntu6 is to be installed
 Depends: g++-4.9 (>=4.9) but it is not installable
 Depends: gcc-4.9 (>=4.9) but it is not installable

我怎样才能在我的电脑上获得g ++ 4.9？

谢谢.

以下是如何在Linux Mint 17.2 Rafaela上安装g ++ - 4.9

1. 转到菜单 - >管理 - >软件源

2. 单击Additional repositories,然后单击Getdeb

3. 点击编辑网址...

4. 替换deb http://archive.getdeb.net/ubuntu trusty-getdeb应用程序

   通过

   deb http://archive.getdeb.net/ubuntu wily-getdeb apps

   然后单击" 更新缓存"

5. 此时你可以去

   sudo add-apt-repository ppa:ubuntu-toolchain -r/test

   sudo apt-get update

   sudo apt-get install g ++ - 4.9

你可以像这样调用你的g ++:

克++ - 4.9

现在你安装了g ++ 4.9.3

作为补充,您可以使用最新的g ++ - 5(g ++ 5.2.1)编译器

sudo apt-get install g ++ - 5
