Learn GCC compilers

Compiling a simple source code

VI hello.c

#include <stdio.h> int main () { printf ("Hello Linux c,i ' m here. Waiting for your congratulations. "); return 0; }

Use the "-o" option to indicate the compiled file name.

GCC Hello.c-o Hello

GCC Common options

Options	Description
-C	Compiles only, does not link to an executable file, and generates only "-O" files. Often used to compile subroutine files that do not contain the main program.
-O	Make the name of the output file
-G	The symbolic information necessary to produce the symbolic debugging tool (GNU GDB).
-O	The compilation and linking process is optimized for processing.
-o2	Better process optimization. (Of course the speed will be slower)
