In Linux, gcc is a commonly used compiler that compiles C, C++, and other source code into executable files. Here are some common ways to use gcc:

  1. Compile a single source file.
  2. Compile the source code in the file “source.c” and create an executable named “output”.
  3. This will compile the source file named source.c and name the generated executable file as output.
  4. Compile multiple source files.
  5. Compile source1.c and source2.c using gcc and create an executable file named output.
  6. This will compile both source1.c and source2.c source files simultaneously, and the generated executable file will be named output.
  7. Select compiler version:
    If you have multiple versions of gcc installed on your system, you can use the following command to choose a specific version of the compiler:
  8. Compile source.c using gcc version and save the output as ‘output’.
  9. For example, if you want to use version 8 of gcc, you can use the command gcc-8.
  10. Specify compiler options:
  11. Compile source.c into an executable named output with all warnings treated as errors.
  12. This will compile the source.c source file and name the generated executable file as output. -Wall and -Werror are compiler options, enabling all warnings and treating warnings as errors, respectively. You can add other options as needed.
  13. Linking to other libraries:
    If your code depends on other libraries, you can use the following command to link them:
  14. Compile the source code in source.c into an executable named output, linking the specified library.
  15. This will compile the source file source.c and name the generated executable file as output. The -l option specifies the name of the library to link. Multiple -l options can be added as needed.
  16. Generate debugging information:
  17. Compile the source code in the file source.c with debugging information enabled and save the executable as output.
  18. This will compile the source file source.c and name the generated executable file output, while also including debugging information in the executable file for use during debugging.

Here are some commonly used methods for using gcc, you can adjust them according to your own needs and specific situations. You can use the “man gcc” command to view more instructions on using gcc.
