How to generate preprocessing, compilation and other files with GCC under Linux

"Gcc-e test.c-o test.i------> preprocessing files generate. i files. 】

2. 1, C language Program generation process
4. C Language Program generation process can be easily divided into: editing, preprocessing, compilation, assembly, link five order break.
6. All of the following operations to the Hello World program for example, the source code file named T.c, the source content is as follows:
8. #include <stdio.h>
10. int main ()
12. {
14. printf ("Hello world\n");
16. return 0;
18. }

    2. Pretreatment Order Break

    Preprocessing order is the preprocessing code in C source processing.

    GCC-E-O t.i t.c

    Steps to read
24. 3

    3. Compile order break

    Compile order is to process the C source code into the assembly.

    Gcc-s-O t.s t.i

    Or

    Gcc-s-O t.s t.c

    Steps to read
26. 4

    4. Assembly Order Break

    The assembly order is to process the assembly code into binary code.

    Gcc-c-O t.o t.s

    Or

    Gcc-c-O t.o t.c

    Steps to read
28. 5

    5. Link Order break

    Link order the binary code is packaged into an executable file format that can be recognized by the operating system, and Linux is the ELF format, which is the PE format on Windows.

    Gcc-o T T.O

    Or

    Gcc-o T t.c

    Steps to read

• 1. 6
  2. 6. Operation Step Break
  3. Running the order, the executable loader with the operating system is responsible for loading and executing the program.
  4. ./T
