Wykonanie, użycie: GNU Compiler Collection.
gcc, formerly known as the GNU C Compiler, compiles multiple languages (C, C++, Objective-C, Ada, FORTRAN, and Java) to machine code. Here we document its use to compile C, C++, or Objective-C code.
gcc compiles one or more programming source files; for example, C source files (
file.c), assembler source files (
file.s), or preprocessed C source files (
file.i). If the file suffix is not recognizable, assume that the file is an object file or library.
gcc normally invokes the C preprocessor, compiles the process code to assemble language code, assembles it, and then links it with the link editor. This process can be stopped at one of these stages using the
-c,
-S, or
-E option. The steps may also differ depending on the language being compiled. By default, output is placed in
a.out. In some cases,
gcc generates an object file having a
.o suffix and a corresponding root name.
Preprocessor and linker options given on the gcc command line are passed on to these tools when they are run. These options are briefly described here, but some are more fully described under entries for cpp, as, and ld. The options that follow are divided into general, preprocessor, linker, and warning options. gcc accepts many system-specific options not covered here.
Note: gcc is the GNU form of cc; on most Linux systems, the command cc will invoke gcc. The command g++ will invoke gcc with the appropriate options for interpreting C++
