(e.g. its width, ...). You can use the options described below to control the formatting algorithm for diagnostic messages, e.g. how many characters per line, how often source location information should be reported. Note that fdiagnostics-color some language front ends may not honor these options. -fmessage-length=nTry to format

source location information once; that is, in case the message is too long to fit on a single physical line and has to be wrapped, the source location won't be emitted (as prefix) again, over and over, in subsequent continuation lines. This is the default behavior. -fdiagnostics-show-location=every-lineOnly meaningful in line-wrapping mode. Instructs the diagnostic messages reporter to emit the same source location gcc force color information (as prefix) for physical lines that result from the process of breaking a message which is too long to fit on a single line. -fdiagnostics-color[=WHEN]-fno-diagnostics-colorUse color in diagnostics. WHEN is ‘never’, ‘always’, or ‘auto’. The default depends on how the compiler has been configured, it can be any of the above WHEN options or also ‘never’ if GCC_COLORS environment variable isn't present in the environment, and ‘auto’ otherwise. ‘auto’ means to use color only when the standard error is a terminal. The forms -fdiagnostics-color and -fno-diagnostics-color are aliases for -fdiagnostics-color=always and -fdiagnostics-color=never, respectively. The colors are defined by the environment variable GCC_COLORS. Its value is a colon-separated list of capabilities and Select Graphic Rendition (SGR) substrings. SGR commands are interpreted by the terminal or terminal emulator. (See the section in the documentation of your text terminal for permitted values and their meanings as character attributes.) These substring values are integers in decimal representation and can be concatenated with semicolons. Common values to concatenate include ‘1’ for bold, ‘4’ for underline, ‘5’ for blink, ‘7’ for inverse, ‘39’ for default foreground color,
