在Ubuntu 14.04.3上安装clang 3.8

我尝试了以下明显的命令：

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

但我得到消息：

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

我尝试过：

sudo apt-get update
sudo aptitude install clang-3.8

但是得到消息：

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

希望使用的clang版本高于3.5。有什么建议么？

看起来14.04.3的最新版本是Trusty Updates中的clang 3.6。但是开发人员维护一个PPA，它应该为您提供最新版本：

LLVM Debian / Ubuntu每晚软件包

要安装3.8，您首先需要添加密钥：

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

然后通过手动/etc/apt/sources.list将以下行添加到（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

屏幕截图显示了该技术：

然后运行以下命令：

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

如下测试安装：

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:~$ 

希望这会帮助您...
