我想在Linux上为嵌入式板设置交叉编译环境。我的Linux主机是ubuntu12.04 32bit。
我已经将gcc和g ++更新到4.8，但是当我apt-get install g ++-arm-linux-gnueabihf时，它总是自动获得4.6版本，无法满足我的目标程序的要求。

在apt-get install g ++-arm-linux-gnueabihf时如何选择gcc版本？
如果我直接获得g ++ 4.8，则无法找到该包：
root@alcht:~# apt-get install gcc-4.8-arm-linux-gnueabihf

我应该更新源列表吗？还是我的gcc依赖项有问题？
