Disabling red error in Qt Creator

Question

The creator of Qt uses its own code analyzer to highlight errors in cpp code. But when I use gcc types, the creator of Qt treats it unsigned __int128 mask = 1;as an error and underlines this line and many subsequent lines. So, how do I turn off underlining errors or get Creator to correctly validate this ad?

Answer 1

Tools → Options → Text Editor → Font and Colors: Find and click "Error" in the "Color Scheme". Click Copy, Ok. Select "No underline" in the "Underline" section.
