cc1plus.exe: error: argument to "-fmessage-length=" should be a non-negative integer
make: *** [atest.o] Error 1

actually in my gcc c++ compller has -c -fmessage-length=0 this flag has been given but my in console window showing above error

Answer 1

This is not actually a make error. make runs other commands (such as g++) to actually build the project. When one of those commands gives an error, make will stop (unless specifically told to ignore the error).

This appears to be a bug in mingw compiler. I've tried -fmessage-length=0 on multiple versions of g++ (4.2.1 for Darwin/Mac, 4.3.2 on Linux) and none of them issued that error (and I could create the error by specifying -fmessage-length=-1).

Answer 2

Remove trailing comma from -fmessage-length=0,
