How to generate obj files after compiling C language code for Linux

If you do not specify what file to compile, gcc default one step, directly generate the executable file
You can try some of the following parameters

-C

  Only activates preprocessing, compilation, and assembly, that is, he only makes the program obj file

  Example usage:

  Gcc-c hello.c

  He will generate the. O obj file

-S

  Only pre-processing and compilation are activated, which means compiling the files into assembly code.

  Example usage

  Gcc-s hello.c

  He will generate the assembly code for. S, which you can view with a text editor

-E

  Just activate the preprocessing, this does not generate the file, you need to redirect it to an output file inside.

  Example usage:

  GCC-E hello.c > Pianoapan.txt

  GCC-E hello.c | More

-O

  Specify the target name, by default, the GCC compiled file is a.out,

  Example usage

  

  Gcc-o hello.asm-s hello.c
