我正在尝试在Ubuntu 14.04 sudo apt-get install gcc-4.5 g++-4.5 gcc-multilib g++-multilib上安装gcc-4.5和g ++ - 4.5但是出现了以下错误：
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？

gcc-4.5或g ++ 4.5不适用于大多数Ubuntu软件发行版。如果您想要获得此版本，请参阅gcc releases和successful builds。
另一个选择是使用“PPA for Ubuntu Toolchain Uploads (restricted)” team的版本。在您的情况下，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。
