C + + Development SDL2 application under Ubuntu14.04

1 Download and install

To http://www.libsdl.org/download Http://www.libsdl.org/release/SDL2-2.0.3.zip source code

After decompression

./configure

Make

sudo make install

Check

Header file:/USR/LOCAL/INCLUDE/SDL2

Library Location:/usr/local/lib

2 Establishing the test procedure:

#include <iostream> #include <SDL.h> #define WIDTH 640#define HEIGHT 480#define BPP 4#define DEPTH 32using Name    Space Std;int Main (int argc, char* argv[]) {sdl_surface *screen;    Sdl_event Event;    int keypress = 0;    int h = 0;    if (Sdl_init (sdl_init_everything) = =-1) {cout << "error:" << sdl_geterror () << Endl;    return 1; } sdl_window* Window = Sdl_createwindow ("Hello", sdl_windowpos_centered, sdl_windowpos_centered, 640, 480, SDL_WIND    Ow_shown);        if (window = = NULL) {cout << "Error:" << sdl_geterror () << Endl;    return 1; }sdl_renderer* Renderer = sdl_createrenderer (window,-1, sdl_renderer_accelerated |    Sdl_renderer_presentvsync);        if (renderer = = NULL) {cout << "Error:" << sdl_geterror () << Endl;    return 1; }sdl_surface* Surface = sdl_loadbmp ("Bk.bmp"); sdl_texture* Texture = sdl_createtexturefromsurface (renderer, surface); Sdl_freesurface (surface); Sdl_renderClear (renderer);    Clear Screen sdl_rendercopy (renderer, texture, 0, 0);    Draw the texture to the renderer sdl_renderpresent (renderer);        while (!keypress) {//drawscreen (screen, h++);                    while (Sdl_pollevent (&event)) {switch (event.type) {case Sdl_quit:                    KeyPress = 1;                Break                    Case sdl_keydown:keypress = 1;            Break    }}} sdl_quit (); return 0;}

3 Write the compiled command build file, as follows:

g++ Sdl_app1.cpp-i/usr/local/include/sdl2-l/usr/local/lib-lsdl2-lpthread

To set execution permissions for this file:

chmod +x Build

Run the Compile command:

./build

Generate Execution File a.out

4 Running the program

./a.out

If you cannot find the. so.0 ..., the case where the dynamic link library cannot be found

To run the command:

sudo vim/etc/ld.so.conf #修改系统共享库搜索路径

Increase in the first line

Include/usr/local/lib

Run the command again:

sudo ldconfig

Run./a.out

The results are working correctly
