GCC: GNU Compiler Collection

  • Referrers to all the different languages that are supported by the GNU compiler.

gcc: GNU C      Compiler
g++: GNU C++ Compiler

The main differences:

  1. gcc will compile: *.c/*.cpp files as C and C++ respectively.
  2. g++ will compile: *.c/*.cpp files but they will all be treated as C++ files.
  3. Also if you use g++ to link the object files it automatically links in the std C++ libraries (gcc does not do this).
  4. gcc compiling C files has less predefined macros.
  5. gcc compiling *.cpp and g++ compiling *.c/*.cpp files has a few extra macros.
