1. New Path
sudo mkdir/madplay
sudo mkdir/madplay/mad

2. Maximum permissions to the path
sudo chmod 777/madplay/madplay/mad

3. Copy four source packages to/madplay and unzip

4. Compile zlib-1.1.4
Go to zlib-1.1.4 Path:
CD zlib-1.2.5/
(1) First configure the Configure file, generate the Makefile, command (--prefix=/madplay/mad/the installation path for the specified final generated library file):
sudo./configure--prefix=/madplay/mad/

(2) Modify Makefile:
sudo vi Makefile
Modify the following three items:
CC=GCC-> CC=ARM-LINUX-GCC
Ar=ar RC-> Ar=arm-linux-ar RC
Ranlib=ranlib-> Ranlib=arm-linux-ranlib

(3) Compiling:
sudo make

(4) Installation:
sudo make install

5: Compiling libid3tag-0.15.1b

Go to libid3tag-0.15.1b Path:
CD libid3tag-0.15.1b/

1) Run the following command

sudo./configure cc=arm-linux-gcc ar=arm-linux-ar ranlib=arm-linux-ranlib--host=arm-linux--prefix=/home/zhao/ Madplay/mad--disable-shared Cppflags=-i/home/zhao/madplay/mad/include/ldflags=-l/home/zhao/madplay/mad/lib

(2) Compiling:
sudo make

(3) Installation:
sudo make install

6: Compiling libmad-0.15.1b

Go to libmad-0.15.1b Path:
CD libmad-0.15.1b/

1) Run the following command

sudo./configure cc=arm-linux-gcc ar=arm-linux-ar ranlib=arm-linux-ranlib--host=arm-linux--prefix=/home/zhao/ Madplay/mad--disable-shared Cppflags=-i/home/zhao/madplay/mad/include/ldflags=-l/home/zhao/madplay/mad/lib

(2) Compiling:
sudo make

(3) Installation:
sudo make install

7. Compile Madplay:
Enter Path/madplay/madplay-0.15.2b
1) Run the following command

./configure CC=ARM-LINUX-GCC Ar=arm-linux-ar ranlib=arm-linux-ranlib--host=arm-linux--prefix=/home/zhao/madplay/ Mad--disable-shared--enable-static--disable-nls cppflags=-i/home/zhao/madplay/mad/include/ldflags=-l/home/zhao/ Madplay/mad/lib

(2) Compiling:
sudo make

(3) Installation:
sudo make install

The resulting madplay are ultimately dynamically compiled, and for static compilation, the final compilation command that is output after make is replicated, and finally the-static is added, as follows:

/usr/local/arm/3.4.1/bin/arm-linux-gcc-wall-g-o2-o madplay madplay.o getopt.o getopt1.o version.o resample.o filter.o TAG.O crc.o rgain.o player.o audio.o audio_aiff.o audio_cdda.o audio_hex.o audio_null.o audio_raw.o audio_snd.o audio_wav E.O audio_oss.o-l/madplay/mad/lib/madplay/mad/lib/libmad.a/madplay/mad/lib/libid3tag.a-lz-lm-static

Enter, ok!

Download the Madplay in the current directory to the Development Board, and then download a MP3 format audio file to the development Board and execute:
./madplay Xxx.mp3
This allows you to hear the MP3 music played by the headset.

The encoding format for MPA1L3 song playback effect is also OK, playback speed is only a little slower than the PC.
The encoding format for MPA2L3 songs is obviously slow to play.
