标签: ubuntu gcc apt

Ubuntu 17.04 上尝试从源代码构建llvm 3.4时,我遇到了 与 gcc 6.3 (描述为here)相关的一些问题,所以我想使用 gcc-4.9 。 但是,当我从终端运行时:

sudo apt install gcc-4.9 --fix-missing

我收到以下错误:

这里发生了什么?谢谢!

似乎gcc-4.9.4确实从主存储库中丢失,而主存储库只有gcc-4.9.3http://us.archive.ubuntu.com/ubuntu/pool/universe/g/gcc-4.9

这解释了来自404 Not Found的{​​{1}}错误 作为第一次修复尝试,您可以尝试以下操作,以防apt能够修复的冲突:

apt

Ubuntu 16.04

在Ubuntu 16.04上,可以从Launchpad Toolchain存储库安装gcc-4.9:

sudo apt-get update --fix-missing
sudo apt-get dist-upgrade
sudo apt-get install gcc-4.9 g++-4.9 gcc-4.9-multilib

Ubuntu 18.04 (可能是17.10,17.04)

如果上述方法不起作用,您可以手动安装gcc-4.9以及所有必需的依赖项,方法是使用sudo apt-add-repository -yu 'deb http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu xenial main' sudo apt update sudo apt-get install gcc-4.9 g++-4.9 gcc-4.9-multilib 抓取所需的软件包并按顺序安装它们:

dpkg

以上在18.04进行了测试,并生成了功能已安装的gcc-4.9。

答案 1 :(得分:0)

使用Ubuntu 18.04 Bionic Beawer,我最终得到了一个相当肮脏的hack(比您在ubuntu土地上看到的要脏得多):

  1. 暂时将source.list从仿生更改为xential
  2. apt更新
  3. aptitude安装gcc-4.9 g ++-4.9
  4. 将sources.list更改回仿生,并进行更新
sudo -i
apt update; aptitude full-upgrade
cd /etc/apt
sed 's/bionic/xential/g' < sources.list > sources.list-xential
mv -v sources.list{,-bionic}
ln -sv sources.list-xential sources.list
apt update
aptitude -y install gcc-4.9 g++-4.9
ln -svf sources.list-bionic sources.list
apt update

这样,您可以使用软件包管理器和官方软件包。我没有破坏任何东西,因为apt不会在不需要的情况下降级。
