2.2.2. Compiling source files to object code


To create object code files from source files without creating an executable file immediately, instruct GCC to create only object code files as its output. This is a basic operation of the build process for larger projects.

Prerequisites

Procedure

  1. At the command line, change to the directory containing the source code file(s).
  2. Run gcc with the -c option:

    $ gcc -c source.c another_source.c

    Object files are created, with their file names reflecting the original source code files: source.c results in source.o.

    注意

    With C++ source code, replace the gcc command with g++ for convenient handling of C++ Standard Library dependencies.
