如何通过 apt 安装最新的 clang 3.8

在这里我找到了如何安装 clang3.8 的说明： http://llvm.org/apt/

所以我执行了：

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

结果：

    --2015-09-19 12:53:09--  http://llvm.org/apt/llvm-snapshot.gpg.key
    Resolving llvm.org (llvm.org)... [sudo] password for user: 192.17.58.186

    2015-09-19 12:53:10 (1,87 MB/s) - written to stdout [3145/3145]
OK

进而：

sudo apt-get install clang-3.8 clang-3.8-doc libclang-common-3.8-dev libclang-3.8-dev libclang1-3.8 libclang1-3.8-dbg libllvm-3.8-ocaml-dev libllvm3.8 libllvm3.8-dbg lldb-3.8 llvm-3.8 llvm-3.8-dev llvm-3.8-doc llvm-3.8-examples llvm-3.8-runtime clang-modernize-3.8 clang-format-3.8 python-clang-3.8 lldb-3.8-dev liblldb-3.8-dbg

但我得到：

我的操作系统是 Linux Mint 17 3.13.0-24-generic #47-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux

为什么 apt-get 找不到这些包？

正如 Orient 在评论中所说，您首先需要添加存储库。但哪个存储库呢？答案就隐藏在您链接的页面上显而易见的地方。由于当前版本为 3.8，因此您需要添加没有版本号的存储库。我不知道您的 Linux Mint 版本可以转换为哪个发行版，但为了让 Ubuntu 14.04 与 Orient 的示例相匹配，您可以使用：

sudo apt-add-repository "deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.8 main"

sudo apt-get update

sudo apt-get install clang-3.8 lldb-3.8

$ clang-3.8 -v
Ubuntu clang version 3.8.0-svn262614-1~exp1 (trunk) (based on LLVM 3.8.0)
