c++ - 如何在 Ubuntu13.10 上安装 clang-3.5 而不删除 gcc-4.8

Question

我想在我的桌面电脑上安装 clang-3.5(最新版本)。(Ubuntu 13.10)我试过基于 this webpage 的安装设置,

详细步骤如下。

1. 我在/etc/apt/sources.list.d/中创建了文本文件并添加了以下行。

   deb http://llvm.org/apt/saucy/ llvm-toolchain-saucy maindeb-src http://llvm.org/apt/saucy/ llvm-toolchain-saucy main

2. 然后，我执行了以下命令。

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

   sudo aptitude install clang-3.5 lldb-3.5

3. 我收到以下警告消息。它似乎正在删除 gcc 和 clang(旧版本)。但我不想删除 gcc-4.8。

是否可以在 Ubuntu13.10 上安装 clang-3.5 而无需删除 gcc-4.8？

如有任何帮助，我们将不胜感激。提前致谢。

Answer 1

将 34 更改为 35，并且可能需要在其中添加一两个 sudo。

export JN
#export JN='-j 8'

svn co http://llvm.org/svn/llvm-project/llvm/branches/release_34/ llvm34
cd llvm34
cd tools
svn co http://llvm.org/svn/llvm-project/cfe/branches/release_34/ clang
cd ..
./configure --enable-optimized --disable-doxygen --prefix=/opt/llvm34
make $JN
make install

如果你想使用它，然后将/opt/llvm3x/bin 添加到你的路径，否则不要添加路径。

clang/llvm 与 gcc 有什么关系我不知道它们是两个完全独立的东西，就像同时安装 vi 和 emacs 一样。
