What is the meaning of 'header'? cpp > stands for preprocessor? Yes, cpp means the preprocessor, and it's not just "output" it's "cpp-output" i.e. it specifies a file which has already been preprocessed. So c-cpp-output is a preprocessed C file (this is the default language gcc assumes for a .i file) And c++-cpp-output is a preprocessed C++ file (the default for a .ii file) c-header means a C header file, which will be turned into a preprocessed header. See http://gcc.gnu.org/onlinedocs/gcc/Overall-Options.html for the file extensions and other languages supported.
