Disabling error underlining with red in Qt Creator

Question

Qt creator uses it's own code analyzer to underline errors in cpp code. But when I use gcc types Qt creator treats unsigned __int128 mask = 1; as an error and underlines this line and many subsequent lines. So how to disable error underlining or make Creator validate this declaration properly?

Answer 1

Tools -> Options -> Text Editor -> Font&Colors: find and chek the "Error" at the "Color Scheme". Click "Copy", "Ok". Select No underline at the Underline section.
