Including the Universal Header bits/stdc++.h in VS Code

Posted on Edited on In Disqus:

Recently, I have often needed to include the universal header bits/stdc++.h when doing Kick Start. However, my beloved editor VS Code always fails to locate this header correctly and shows a red squiggly error. As a programmer, I absolutely cannot tolerate that, so I tried to solve the problem. I searched online for many solutions, but most of them did not directly solve my issue. So I am summarizing my own solution here for everyone to use.

Programming environment:
g++ 9.1.0, Mac 10.14.2, VS Code 1.45.1

The overall idea is:

  1. Find the path to the GCC compiler header files,
  2. Change the VS Code settings so that it can find bits/stdc++.h using the paths above.
1
gcc-9 -v -E -x c++ -

gcc include path

The figure shows the path order used by the compiler by default. Add all these paths to VS Code’s includePath.

Done!
