I've taken to pasting this in an open code-editor window to get some basic syntax highlighting and enable reformatting with regex's. Has anyone invented a more automated method? c++ c gcc gcc-warning share|improve this question asked Mar 17 '09 at 23:27 mikeh 1 I just make the window very wide... –i_am_jorf Mar 17 '09 at 23:33 And the font very small ;) –Anonymous Mar 17 '09 at 23:35 1 and then stop using gcc. :D –Robert P Mar 17 '09 at 23:44 2 Clarification: I love intel's c++ compiler. The messages are clean, short, and pointed. Back when I still had a license, I'd test my compiles in intel's compiler before I built with GCC just to find the big problems. –Robert P Mar 17 '09 at 23:45 @Robert I'm intrigued, hope I get a chance to try that sometime. Not appropriate on the current project unfortunately... –mikeh Mar 18 '09 at 4:28 | show 1 more comment 8 Answers 8 active oldest votes up vote 14 down vote I've found colorgcc to be invaluable. By introducing coloring, it becomes much easier to mentally parse the text of gcc error messages, especially when templates are involved. share|improve this answer answered Mar 17 '09 at 23:43 Mr Fooz 39.8k35083 1 Hey, I posted that with a temp account and now I can't follow up with it, but I wanted to say thanks for this -- that is an awesome utility and just the sort I was looking for. –mikeh Mar 18 '09 at 4:24 Glad to be of service. –Mr Fooz Mar 18 '09 at 11:39 I like this, but I would prefer message simplification like gccfilter and stlfilt does, although stlfilt doesn't do coloring –Dolan Antenucci Oct 5 '12 at 2:34 1 colorgcc is hackable. You might try modifying its source to run it through your favorite filtering program. –Mr Fooz Mar 19 '13 at 17:25 2 GCC tru

There are also three other packages I found: Johannes SchlĂĽter's colorgcc, or this package in German, or this Sourceforge project share|improve this answer answered Jun 23 '09 at 12:37 user9876 7,08362653 add a comment| up vote 4 down vote This is really basic, but I've been using grep... make 2>&1 | grep --color -iP "\^|warning:|error:|" just to quickly draw the eye to the error line and offending section pointed to by ^. I've found other methods over-use colour and you end up with the same problem. I guess you could also inject colour escape sequences with sed. share|improve this answer answered Aug 14 '14 at 10:58 jozxyqk 7,72541770 add a comment| up vote 1 down vote The warn_summary script is pretty nice You can get a count of all your warnings, the type and also just print out the warnings without all the other output from gcc. gcc <...> | tee buildoutput warn_s
source file, and ":30:" is the line number where the error was located. The "undeclared" error is a common mistake. All variables must be declared before they are used, and if you forget, you'll see this error. http://users.csc.calpoly.edu/~jdalbey/101/Resources/errormessages.html It means the compiler didn't find a declaration for a variable prior to its http://forums.codeblocks.org/index.php?topic=15306.0 first use. The error can also occur if you spelled the variable name differently in two places. The compiler is "case-sensitive" so "DOG" and "dog" are two different variables; pay careful attention to upper and lower case letters. /tmp/ccJiZokm.o: In function `main': conepainting.c:(.text+0x63): undefined reference to `sqrt' collect2: ld returned 1 exit status You gcc error forgot to compile with the math library. Provide the "-lm" flag (that's the letter "l" not the numeral "1" to the compiler, like this: gcc -lm conepainting.c no newline at end of file.

Here is an example:Quote from: gccfilename.h:29:6: note: expected ‘CHAR *’ but argument is of type ‘CARD8 *’Unfortunately they threated as errors by C::B output parser.Does anyone know how to fix this?

Posts: 7062 Re: Compiler output parsing: gcc notes « Reply #2 on: September 28, 2011, 01:59:03 pm » I just (hopefully) fixed this bug in trunk.It occurred, because newer gcc's give the column of the error/note/warning, while older versions < 4.5 only did this for preprocessor messages (as far as I know).So the compiler note was incorrectly treated as preprocessor-error.
