[SOLVED] how to colorize compilation's output?

nTia89 · 2014-10-31 17:06:37

hi fellows,
I've recently read http://www.phoronix.com/scan.php?page=n … px=MTM2MzI
that GCC is now able to show a colorized output with this magic switch

-fdiagnostics-color=always

now, my question is: where I should put it?

It's a command line switch, you put it on the command line. If you want it always enabled there is a way to do that. Perhaps you should RTFM.

nTia89 · 2014-10-31 17:27:12

do you mean

/etc/makepkg.conf

?

No.

It's a command line option for gcc, you put it on the command line when you type a gcc command. If you want it to be automatic it is described in the man page how to do that - the man page for gcc. RTFM!

1) I find that if I set the environment variable

GCC_COLORS

, gcc interprets it as

--fdiagnostics-color=auto

but it's not what I want.....
2) why I can't put it into my

/etc/makepkg.conf

, in the

CFLAGS

line, because it contains other switches?

Out of curiosity, why do you want it set to always instead of auto? Without RTFM-ing myself, I imagine that it adds the color escape sequences only if stdout is a terminal.

I don't think it will harm anything to put it in your CFLAGS.

just curiosity

You can put it in your makepkg.conf if you want it to only work when you run makepkg - but that's not at all what you asked.

Just export that var in your ~/.bashrc or whatever.

export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01'

man gcc wrote:

-fdiagnostics-color[=WHEN]
-fno-diagnostics-color
Use color in diagnostics. WHEN is never, always, or auto. The default is never if GCC_COLORS environment variable isn't present in the environment, and auto otherwise.
