executable not found; please configure clang-executable

Question

Clang format is not working in VSCode Linux (Ubuntu). After installing clang-format in VSCode, I tried to invoke it and it is giving this error:

executable not found; please configure clang-executable. 
Clang-format is available under '/home/alex/.vscode/extensions/ms-vscode.cpptools-0.10.3/LLVM/bin/clang-format'

Answer 1

My system & settings:

• Ubuntu 20.04.1 LTS
• Visual Studio 1.51.1
• VS extension: Clang-formatter v1.9.0 by Xaver

After installing the extension it was not working. When I looked inside the extension folder in the home folder

~/.vscode/extensions/xaver*

Since no bin files were there I installed clang separately with:

sudo apt install clang-format

After this installation the extension in Visual Studio started working.

Answer 2

Even thought I tried configuring the vscode setting.json it was not picking up. Then got the info from https://web.archive.org/web/20170517131553/http://www.codepool.biz/vscode-format-c-code-windows-linux.html and created a link to the target

sudo ln -s /home/alex/.vscode/extensions/ms-vscode.cpptools-0.10.3/LLV
M/bin/clang-format /usr/bin/clang-format
