Linux C Programming: The development environment of C language under Linux

---restore content starts---

Today began to follow the Linux C programming related video of the note, I hope to continue ...

1. The composition of the development environment

　　editor : VI;

　　compiler : Select the GNU C + + compiler for GCC;

　　Debugger : widely used gdb;

　　function library : glibc;

　　System Header File : Glibc_header;

2. Precautions to install Linux

The GCC/GDB can be installed automatically by selecting "Development Tools" in "Program development" during installation.

If you want to develop a graphical interface, you also need to choose GNOME/KDE software development.

3, IDE (Integrated development environment: Set editing, compilation, debugging and other functions in a tool)

Kylix: Known as Linux under the Dephi;

Kdevelop

Rhide: Similar to turbo C + +

4. Compiler: GCC (GNU ccompiler)

is the GNU launch of the multi-platform compiler, the following is the GCC support compiled some of the source file suffix and its interpretation

　　　　. c suffix C language source code file

The. h suffix is the header file that the program contains

The. o suffix is the compiled target file

Example: Gcc-o Hello hello.c Note: 1, the GCC compiles our source program; 2,-o option requires the compiler to give us the output executable file named Hello; 3, hello.c is our source program file; 4, execution  can see the program's Output results

To view the GCC version number:

Gcc-version

5, Function library: glibc

GLIBC is a C library that provides system bar and call functions, such as open,malloc,printf, etc.

View the version of GLIBC:

ls/lib/libc-*

6. System Header File: Glibc_header

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

If the user installs these packages less during installation, it is impossible to compile the C source program, which can be quickly installed in the Linux C Development language environment through the RPM package.

7, Linux under the C program development process:

(1) Using VI tools to edit the writing source program;

(2) Save as *.C;

(3) Compile the binary executable file with GCC;

(4)./a.out Execution (when GCC does not specify an executable file name with the-o option);

(5) A problem can be debugged using GDB;
