cc command in Linux basically stands for C Compiler and is an alternative to gcc or clang command. With the help of this command, users can call the gcc on Linux systems which is used to compile C language codes and create executable files.
The compiler’s essential task is to translate a computer program from one form to another (mostly one language to other). While compiling C program, the compiler actually goes through a number of steps to translate it into machine language which can be executed on targeted platforms.
Syntax of cc command in Linux
Options available to use with cc command
- -o: Used for compiling the source_file.c, and create an executable output file with a specified name.
- -Wall: Used for compiling source_file.c and check for errors or warnings in the program.
- -w: Compiles source_file.c, but suppresses all the warnings.
- -g: Compiles source_file.c and create a debugging version of the executable output file.
- -c: Compiles source_file.c and created an object file source_file.o that can be later linked to create an executable file.
- -L DIR: Used for searching header files in specified directory while compiling source_file.c.
- -ansi: Alongwith compiling the source_file.c, it also makes sure if the code follows strict ANSI standards.
- -v: Compiles source_file.c and prints a verbose output.
Examples of cc command in Linux
1: Compile a file servo.c, and the output will be written in a.out
2: Compile servo.c and the output will be written to servo.exe
cc servo.c -o servo.exe
3: Compile servo.c and output will be written in servo.exe, while the warnings will be displayed if occurs
cc servo.c -Wall -o servo.exe
4: Compile servo.c to servo.exe, while linking the libX11 library and showing warnings if occur
cc servo.c -Wall -lX11 -o servo.exe
5: Compile servo.c to servo.exe, while linking the libX11 library and follow the ANSI C standards. Also to show all warnings if occur.
cc servo.c -Wall -ansi -lX11 -o servo.exe
