Oct 5, 2008 · GCC or G++ just choose a different front-end with different default options.

By default, gcc selects the language based on the file extension, but you can force gcc to select a different language backend with the -x option thus: gcc -x c++ More options are detailed on the gcc man page under "Options controlling the kind of output". See e.g. gcc(1) - Linux man page (search on the page for the text -x language).

If the file name ends with ".S" (uppercase 'S'), then gcc applies the C preprocessor on the source file (i.e. it recognizes directives such as #if and replaces macros), and then calls the assembler on the result. So, on a general basis, you want to do things like this: gcc -S file.c -o file.s gcc -c file.s
