Remove File Name from gcc/g++ Compile Result

Question

I want to remove file names from gcc/g++ compile error messages.

When I run gcc myfolder/temp.c, the result is:

myfolder/temp.c:5:1: error: unknown type name ‘voi’
myfolder/temp.c:87:6: error: conflicting types for ‘max’
myfolder/temp.c:5:5: note: previous declaration of ‘max’ was here

But I want this:

5:1: error: unknown type name ‘voi’
87:6: error: conflicting types for ‘max’
5:5: note: previous declaration of ‘max’ was here

Is there a gcc flag for that?

I doubt there is an option for this but you could achieve the same result using standard utilities. For instance with cut(1)

 gcc -c myfolder/temp.c 2>&1 | cut -d: -f2-

Thanks. Now I want to decrease line numbers by two. I want to change above result to:

3:1: error: unknown type name ‘voi’     85:6: error: conflicting types for ‘max’     3:5: note: previous declaration of ‘max’ was here

How can I do this?

@MJNaderi that would require several operations: line splitting, arithmetics and concatenation, too much for a standard pipeline filter, but a few lines of perl or awk script would do that. E.g. awk -F: '/^[^:]+:[1-9][0-9]*:/ {printf( "%d", $2 + 2) ; for(i=3;i<= NF;i++) {printf( ":%s", $i) ;} printf ("\n"); }'
