- 介紹

• 場景:折騰atom,遇到其中外掛autocomplete-clang 無法正常工作.
• 原因&分析:先下的clang 5.0結果要在終端下要這樣clang-5.0 才可以呼叫,如果修改atom外掛配置,會報string錯誤,估計只能識別clang命令.

- 解決辦法

• 先更新下軟體庫並安裝庫中的老版本(clang3.8)
  
  • sudo apt-get update
  • sudo apt-get install clang
• 在安裝新版本的clang(5.0)
  
  • sudo apt-get update
  • sudo apt-get install clang-5.0
• 接下來按下文修改系統預設行為的命令按提示執行即可

Making latest version available as clang
This version is installed side-by-side with the default clang 3.8. To run it, you have to explicitly say clang-5.0. clang will either refer to 3.8 (if you’ve installed it) or nothing at all.

You can reconfigure the system so that clang refers to clang 5:

sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-3.8 100
sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-5.0 1000
sudo update-alternatives --install /usr/bin/clang++ clang /usr/bin/clang-3.8 100
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.8
 
 100
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-5.0 1000
sudo update-alternatives --config clang
sudo update-alternatives --config clang++

This might help if you have scripts that hard-code name of the compiler and don’t allow over-writing it.
