madplay 在ARM上的移植

1.    下载源码包

 

准备源码包 madplay-0.15.2b.tar.gz，libmad-0.15.1b.tar.gz，
libid3tag-0.15.1b.tar.gz 和 zlib-1.1.4.tar.gz

 

我使用的交叉编译器为gcc-3.4.1，建立必要的文件夹，用于存放文件

 

[nick@localhost nick]mkdir madplay

[nick@localhost nick]cd madplay

 

将以上源码包拷贝到此并解压

 

[nick@localhost madplay]tar –zxvf  zlib-1.1.4.tar.gz

[nick@localhost madplay]tar –zxvf  libid3tag-0.15.1b.tar.gz

[nick@localhost madplay]tar –zxvf  libmad-0.15.1b.tar.gz

[nick@localhost madplay]tar –zxvf  madplay-0.15.2b.tar.gz

[nick@localhost madplay]mkdir lib

 

2.    编译zlib-1.1.4

 

[nick@localhost madplay]cd zlib-1.1.4

首先配置configure 文件

 

[nick@localhost zlib-1.1.4]./configure --prefix=/home/nick/madplay/lib

修改Makefile

 

[nick@localhost zlib-1.1.4]vi Makefile
CC=arm-linux-gcc
AR=arm-linux-ar rc
RANLIB=arm-linux-ranlib

[nick@localhost zlib-1.1.4]make

[nick@localhost zlib-1.1.4]make install

3.    编译libid3tag

 

[nick@localhost libid3tag-0.15.1b]./configure CC=arm-linux-gcc --host=arm-linux --prefix=/home/nick/madplay/lib --disable-shared CPPFLAGS=-I/home/nick/madplay/lib /include LDFLAGS=-L/home/nick/madplay/lib/lib

 

[nick@localhost libid3tag-0.15.1b]make

[nick@localhost libid3tag-0.15.1b]make install

 

4.    编译libmad

 

[nick@localhost libmad-0.15.1b]./configure CC=arm-linux-gcc --host=arm-linux --prefix=/home/nick/madplay/lib --disable-shared CPPFLAGS=-I/home/nick/madplay/lib /include LDFLAGS=-L/home/nick/madplay/lib/lib

 

[nick@localhost libmad-0.15.1b]make

[nick@localhost libmad-0.15.1b]make install

 

5. 编译madplay

 

[nick@localhost madplay-0.15.2b]./configure CC=arm-linux-gcc --host=arm-linux --prefix=/home/nick/madplay/lib --disable-shared CPPFLAGS=-I/home/nick/madplay/lib /include LDFLAGS=-L/home/nick/madplay/lib/lib

 

[nick@localhost madplay-0.15.2b]make

 

这样会在madplay-0.15.2b目录下生成madplay的可执行文件，因为是动态编译，所以还要查看一下需要的动态库

[nick@localhostmadplay-0.15.2b]/usr/local/arm/3.4.1/bin/arm-linux-readelf -d madplay

 

输出一大堆信息，最上面显示了编译所需的动态库：libm.so.6和libc.so.6，将动态库拷贝到根文件系统的/usr/lib目录下（先查看，如果已经有了则不需要）

 

将madplay复制到U盘，复制一首歌曲到U盘，然后插入并挂载U盘（也可以通过nfs）

 

[root@ /]#mount -t vfat -o iocharset=cp936 /dev/uba1 /mnt/usb

[root@ /mnt/usb]#ls

1.files                 Timer.txt               quartus60

1.html                  bootex.log              1.mp3                   clock                   按键中断.rar

1.wav                   found.000               电子时钟

2.mp3                   libm.so.6               王力宏.-.[心·跳].专辑

NiosII范例              madplay              

Screen.ddb              my                      新建文件夹

Timer.pdf               picture.bmp             新建文件夹 (2)

将madplay复制到/usr/bin目录下

 

[root@ /mnt/usb]#cp ./madplay  /usr/bin

 

执行madplay程序

[root@ /mnt/usb]#madplay -r 2.mp3

哈哈，这样你就可以王力宏的歌声，音质还不错~~
