By default, CPPFLAGS will be given to the C preprocessor, while CXXFLAGS will be given to the C++ compiler. The GNU Make Manual is a good resource for questions like this (see Implicit Variables ). CPPFLAGS are for the C preprocessor, while CXXFLAGS are for the C++ compiler. See here. CXXFLAGS is for flags for the C++ compiler, and is only passed when compiling and linking C++.
