One proposal: -Werror makes all warnings into errors, preventing compilation (see

The latter might, however, have something to do with my not being able to read. Use -Werror -Wfatal-errors (that will stop after the first error, not trying to continue). Richard.

Gcc Werror

it only takes a minute: Sign up gcc compiler not stop on first error up vote 5 down vote favorite 1 How does one get gcc to not stop compiling after the first error. Is there a compiler flag https://gcc.gnu.org/ml/gcc/2006-05/msg00275.html that will do this? Basically I'm wanting to remove a class, but i'm not sure how much of an impact that will have, so i'm wanting to determine how many classes would have provblems if i, say, remove the class from the makefile. Is there a better way to determine this impact? gcc compiler-construction compiler-errors compiler-flags share|improve this question asked Nov 21 '12 at 16:08 shadonar 3621625 add a comment| 2 Answers 2 active oldest votes up vote 15 http://stackoverflow.com/questions/13497307/gcc-compiler-not-stop-on-first-error down vote accepted There's a GCC compiler option -Wfatal-errors to stop after the first error: -Wfatal-errors This option causes the compiler to abort compilation on the first error occurred rather than trying to keep going and printing further error messages You can also use -Werror if you want to treat warnings as errors so that you'll catch any warning that might be generated when you remove your class. share|improve this answer answered Nov 21 '12 at 16:29 P.P. 58.4k768119 add a comment| up vote 1 down vote Is there a better way to determine this impact? Use the refactoring support, built-in in many IDEs. For example, with NetBeans, you can choose to rename a class and preview all affected places. Without an IDE, you can rename the class/method/field, instead of deleting it and gradually, with several compilation runs, change all usages of the old name, where the compiler gives an error. Then grep for the new name. share|improve this answer answered Nov 21 '12 at 16:46 chill 12k11834 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

I think I have MinGW 5.1.6 installed. When I enable the "Stop compiling after the first error" option in the build settings, I get this message from the compiler:cc1.exe: error: unrecognized command line option "-Wfatal-errors"This is such a basic setting that I think should be the default mode. I don't understand why anyone would want any other behavior, at least by defaultDo I need to install another version of MinGW? Which versions will support this option?Thank you. This issue is the primary reason I am looking for an alternative to Visual Studio. « Last Edit: August 25, 2010, 01:30:48 am by JMK » Logged oBFusCATed Developer Lives here!
