'-fno-diagnostics-show-caret'
By default, each diagnostic emitted includes the original source
line and a caret '^' indicating the column. This option suppresses
this information. The source line is truncated to N characters, if
the '-fmessage-length=n' option is given. When the output is done
to the terminal, the width is limited to the width given by the
'COLUMNS' environment variable or, if not set, to the terminal
width.
'-fno-diagnostics-show-labels'
By default, when printing source code (via
'-fdiagnostics-show-caret'), diagnostics can label ranges of source
code with pertinent information, such as the types of expressions:
printf ("foo %s bar", long_i + long_j);
~^ ~~~~~~~~~~~~~~~
| |
char * long int
This option suppresses the printing of these labels (in the example
above, the vertical bars and the "char *" and "long int" text).
'-fno-diagnostics-show-line-numbers'
By default, when printing source code (via
'-fdiagnostics-show-caret'), a left margin is printed, showing line
numbers. This option suppresses this left margin.
