Ubuntu 14.04 安装 gcc-4.5 和 g++4.5

Question

我尝试在 Ubuntu 14.04 上安装 gcc-4.5 和 g++-4.5

sudo apt-get install gcc-4.5 g++-4.5 gcc-multilib g++-multilib

但出现以下错误：

Package gcc-4.5 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

Package g++-4.5 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 'gcc-4.5' has no installation candidate
E: Package 'g++-4.5' has no installation candidate

谁能告诉我我需要做什么？

Answer 1

gcc-4.5 或 g++4.5 不在大多数 Ubuntu 软件发行版中。如果您想确切地获得此版本，请参阅 gccreleases 和 successful builds。

另一个选择是使用“PPA for Ubuntu Toolchain Uploads (restricted)”团队的版本。根据您的情况，添加

deb http://ppa.launchpad.net/ubuntu-toolchain-r/ppa/ubuntu trusty main 
deb-src http://ppa.launchpad.net/ubuntu-toolchain-r/ppa/ubuntu trusty main

到您的源列表，然后运行

sudo apt-get update

。您将能够使用

sudo apt-get install gcc-4.5

。
