gcc error and warning messages wrap at 80

gcc error and warning messages wrap at 80

[Justin Findlay]

Why do gcc's error and warnings auto wrap at 80 characters, rather than at
the terminal buffer width?  It makes reading these messages difficult
especially if you have long paths and are using C++ templates.

Hi Justin,

You can set where the buffer wraps.

g++ -fmessage-length=$COLUMNS foo.cpp -o foo

Or to disable it:

g++ -fmessage-length=0 foo.cpp -o foo

I usually disable it.

Can I do this globally, as in when I build gcc?

Hello,

I agree that wrapping at 80 characters always doesn't
seem a very brilliant idea. I'd file a bug report in
bugzilla for this one.
