After deleting the wrong content, it will still be marked in red until compiled again

Question

There is something wrong with my vscode. When a compilation error occurred, I corrected the error, but the correction will not be reflected in the red mark untill compiled again. g++ version 13.1.0

Here are screenshots of the error. An error occurred. enter image description here it doesn't disappear evenif i delete it. enter image description here

Here's my tasks' configuration. enter image description here

I want the red tilde to disappear immediately when my code has no errors instead of remaining there until the next compilation.

Answer 1

That's the effect of "problemMatcher": ["$gcc"]. Ditch it.

Simply having an intellisense plugin installed (either the stock C/C++ plugin, or Clangd, depending on your preference) should give you squiggles updating in real time.
