• 移植SDL运行库到Tiny6410 上


    在移植游戏之前, 我们首先需要将 SDL/SDL_mixer/SDL_ttf/SDL_image 这四个库移植到 Tiny6410 上, 另外还需要 iconv 库。

    libiconv-1.13.1.tar.gz Iconv 库 下载:http://ftp.gnu.org/pub/gnu/libiconv/
    SDL-1.2.14.tar.gz SDL 库 http://www.libsdl.org/download-1.2.php
    SDL_image-1.2.8.tar.gz SDL_image 库 http://www.libsdl.org/projects/SDL_image/release/
    SDL_ttf-2.0.9.tar.gz SDL_ttf 库 http://www.libsdl.org/projects/SDL_ttf/release/
    SDL_mixer-1.2.9.tar.gz SDL_mixer 库 http://www.libsdl.org/projects/SDL_mixer/release/

    在 /opt/mini6410 目录下创建目录 games 来作为我们本次移植工作的工作目录,输入以下命令创建:

    # mkdir –p /opt/mini6410/games

    再在 games 目录下创建一个 output 目录,用来存放编译生成的可执行文件或者类库等:

    # cd /opt/mini6410/games
    # mkdir output

    编译iconv库

    # tar xvzf /tmp/libiconv-1.13.1.tar.gz
    # cd libiconv-1.13.1
    # ./configure --host=arm-linux --prefix=/opt/mini6410/games/output
    # make
    # make install

    编译SDL库

    # cd /opt/mini6410/games
    # tar xvzf /tmp/SDL-1.2.14.tar.gz
    # cd SDL-1.2.14
    # ./configure --prefix=/opt/mini6410/games/output 
    --disable-video-nanox -disable-video-qtopia
    --disable-video-photon --disable-video-ggi --disable-video-svga
    --disable-video-aalib --disable-video-dummy --disable-video-dga
    --disable-arts --disable-esd --disable-alsa --disable-video-x11
    --disable-nasm --enable-joystick --enable-input-tslib
    --enable-video-fbcon --host=arm-linux --build=i386
    # make # make install

    编译SDL_image库

    # cd /opt/mini6410/games
    # tar xvzf /tmp/SDL_image-1.2.8.tar.gz
    # cd SDL_image-1.2.8
    # ./configure --enable-shared --enable-static --host=arm-linux --build=i386 
    --prefix=/opt/mini6410/games/output --enable-bmp --enable-gif --enable-jpg 
    --enable-png --enable-tif --enable-pnm --enable-xpm 
    --disable-sdltest SDL_CFLAGS="-I/opt/mini6410/games/output/include" 
    SDL_LIBS="-L/opt/mini6410/games/output/lib -lSDL" 
    LIBPNG_CFLAGS="-I/opt/mini6410/games/output/include" 
    LIBPNG_LIBS="-L/opt/mini6410/games/output/lib -lpng" 
    CPPFLAGS="-I/opt/mini6410/games/output/include/SDL -I/opt/mini6410/games/output/include/" 
    LDFLAGS="-L/opt/mini6410/games/output/lib -ljpeg -lts -lpng -liconv"
    # make
    # make install

    在这里会提示报错信息

    checking for C compiler default output file name... configure: error: C compiler cannot create executables
    See `config.log' for more details.

    打开config.log文件会在在最低部看到出错的地方 这里我们安装这几个库就行了

    apt-get install libjpeg-dev
    apt-get install libts-dev
    apt-get install libpng-dev

     编译SDL_ttf库

    # cd /opt/mini6410/games
    # tar xvzf /tmp/SDL_ttf-2.0.9.tar.gz
    # cd SDL_ttf-2.0.9
    # ./configure --host=arm-linux --prefix=/opt/mini6410/games/output 
    --enable-shared --enable-static --disable-sdltest --with-freetype-prefix=/opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/sys-root/usr/ --with-sdl-prefix=/opt/mini6410/games/output/ CFLAG="-I/opt/mini6410/games/output/include" LDFLAGS="-L/opt/mini6410/games/output/lib -lSDL -lts -liconv -lfreetype"

    和上一个一样在编译的时候也会报错  安装库

    apt-get install libSDL-dev
    apt-get install libfreetype6-dev

    在编译之前手工修改 Makefile,去掉 OpenGL 相关处理:

    # vi Makefile

    定位到 123 行,将以下内容中的“-I/usr/include -DHAVE_OPENGL”删除(红色字体部分):
    CFLAGS = -g -O2 -I/usr/include/freetype2 -I/opt/mini6410/games/output/include/SDL
    -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include -DHAVE_OPENGL
    再定位到 143 行,将:
    GL_LIBS = -L/usr/lib -lGL
    改成
    GL_LIBS =
    再定位到 266 行,将:
    glfont_LDADD = libSDL_ttf.la -L/usr/lib -lGL -lm
    改成
    glfont_LDADD = libSDL_ttf.la -lm
    清空源代码文件 glfont.c 中的源代码 (先删除,再用 vi 创建):
    # rm glfont.c.-f
    # vi glfont.c
    在 vi 编辑器中输入以下内容并保存:
    void main() {}

    最好, 输入命令编译并安装:
    # make
    # make install
