Its sole function is to process the “#…” directives, such as splicing the "#include”-d headers into the source file, removing parts of the source in the wrong arm of an “#ifdef”, or expanding "#define”-d macros. > However, the GNU compiler is also capable to select the proper language and > use the proper tools for compillation, so GNU's cpp will compile… I believe > Fortran, or even Java, if the proper alternative GNU compiler present. > Not at all. Cpp is used automatically by the C compiler to deal with macros in the source file. It’s not intended to call the compiler itself, much less smart enough to choose the right compiler for the language.
