在 Ubuntu 14.04.3 上安装 clang 3.8

Question

我尝试了以下明显的命令：

sudo apt-get update
sudo apt-get install clang-3.8

但我收到消息：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我试过：

sudo apt-get update
sudo aptitude install clang-3.8

但得到消息：

Couldn't find package "clang-3.8".  However, the following
packages contain "clang-3.8" in their name:
  clang-3.8-doc

希望有一个比 3.5 更新的 clang 版本。有什么建议？

看起来 14.04.3 的最新版本是Trusty Updates 中的 clang 3.6。但是开发人员维护了一个 PPA，它应该为您提供最新版本：

LLVM Debian/Ubuntu 每晚包

要安装 3.8，您首先要添加密钥：

wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key|sudo apt-key add -

然后通过手动添加以下行/etc/apt/sources.list（或使用 gui '软件和更新'）来添加 3.8 的存储库：

deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.8 main

此处的屏幕截图以演示该技术：

然后运行以下命令：

sudo apt-get update
sudo apt-get install clang-3.8 lldb-3.8

测试安装如下：

andrew@corinth:~$ clang-3.8 --version
clang version 3.8.0-svn262614-1~exp1 (branches/release_38)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
andrew@corinth:~$ 

希望这能让你继续前进......
