Development environment for Linux C programs

1. Composition of the development environment

1. Editor Vim,vi
2. Compiler GCC
3. Debugger GDB
4. function library glibc
5. System Header File Glibc_header

2.GCC compiler

Powerful and superior multi-platform compiler, GCC can compile and connect C, C + + language source programs into executable files.

file with. c suffix, C language source code file

A file with a suffix of. h is a header that is included in the program.

Files with. I suffix are pre-preprocessed C source code files

Files with an. o suffix are the compiled target files

. s is the suffix of the file, is the assembly language source code files

Options for the GCC compiler

-O requires output executable file

-C requires the compiler to output the target code without the need to output an executable file

-G requires the compiler to output debugging information at compile time

3.glibc

is the main function library of C under Linux

A C library that provides system calls and basic functions that all dynamic, connected programs use.

4.glibc_header

If the system header file is missing, many C programs that use the system function will not compile
