gcc man手册03节

1、GCC介绍

GCC:GNU Compiler Collection(GNU 编译器集合)，它可以编译C、C++、JAV、Fortran、Pascal、Object-C等语言。

gcc是GCC中的GUN C Compiler（C 编译器）。

g++是GCC中的GUN C++ Compiler（C++编译器）。

zSeries Options See S/390 and zSeries Options.543       Options Controlling the Kind of Output544           Compilation can involve up to four stages: preprocessing, compilation proper, assembly and linking, always in545           that order.  GCC is capable of preprocessing and compiling several files either into several assembler input546           files, or into one assembler input file; then each assembler input file produces an object file, and linking
