The 32-bit C compiler emits errors as follows: the phase of the compiler which detects an error or warning, identifies itself first, then it prints whether it found an error or warning. The next printed items are the file name, line number and description of the error.
Fortran error messages are similar except the compiler phase name is omitted.
Two examples illustrate this:
C:
Fortran:%cc -32bit test.c cfe: Error: test.c, line 4: Syntax Error
Under the 64-bit compiler, back end warning messages start with the string "!!!". Error messages start with the string "###". This allows easier searches in log files. C error messages are similar to the 32-bit compiler's error messages, although they are usually more descriptive.% f77 -32bit err.f Error on line 6 of err.f: syntax error
Here the same files compiled with the 64-bit compiler result in the following error messages:
C:
Fortran:%cat test.c #include <stdio.h> main () { printf ("hhelp")
} %cc -64bit test.c "test.c", line 4: error(1065): expected a ";"
}
^
%cat err.f
program test

end
% f77 -64bit err.f
### 8 formatr('This is a test')

### error Statement unrecognizable as any known statement type. ###
### error Label "8" is not the label of a format statement. ###
