Development Environment for Linux C Programs

Development Environment for Linux C Programs

1. Composition of the Development Environment

2. gcc compiler

Multi-platform compiler with powerful functions and superior performance. gcc can compile and connect the c and c ++ language source programs into executable files.

Files suffixed with. c and c source code files

A file suffixed with. h is the program's header

Files suffixed with. I are pre-processed C source code files.

A file suffixed with. o is the target file after compilation.

. S is a suffix file, which is the source code file of the assembly language.

Gcc compiler options

-O requires output of executable files

-C requires the compiler to output the target code without outputting executable files.

-G requires the compiler to output debugging information during compilation.

3. glibc

Is the main function library of C in linux.

Provides a C library for system calls and basic functions. It is used by all dynamic and connected programs.

4. glibc_header

If the system header file is missing, many C Programs that use system functions cannot be compiled.
