注释编译
--prefix:指定你编译之后，执行make install时，生成的目录，没有使用--prefix的话，就会执行默认的目录，什么目录执行之后就知道了
CC=arm-linux-gcc
--host： 编译器类型如用arm-unknown-linux-gnueabi-gcc则填--host=arm-unknown-linux-gnueabi
--disable-debugging:禁止调试
--enable-static:静态库
--enable-shared:动态库
-I :include 所需的头文件路径
-L :lib 所需的库的路径
一 编译zlib-1.1.4
1 cd zlib-1.1.4
2 vi configure
将
24 AR=${AR-"ar rc"}
25 RANLIB=${RANLIB-"ranlib"}
63 cc=${CC-gcc}
修改为：
AR=${AR-"arm-linux-ar rc"}
RANLIB=${RANLIB-"arm-linux-ranlib"}
cc=${CC-arm-linux-gcc}
3
./configure --prefix=/opt/madplay_source/build
4 make && make install
二 编译libid3tag-0.15.1b
1 tar xvzf libid3tag-0.15.1b.tar.gz
2 cd libid3tag-0.15.1b
3 ./configure CC=arm-linux-gcc --prefix=/opt/madplay_source/build --host=arm-linux --disable-debugging --enable-static CPPFLAGS=-I/opt/madplay_source/build/include LDFLAGS=-L/opt/madplay_source/build/lib
4 make && make install
三 编译libmad-0.15.1b
1 tar -xvzf libmad-0.15.1b.tar.gz
2 cd libmad-0.15.1b
3 ./configure CC=arm-linux-gcc --prefix=/opt/madplay_source/build --host=arm-linux --disable-debugging --enable-static CPPFLAGS=-I/opt/madplay_source/build/include LDFLAGS=-L/opt/madplay_source/build/lib
或者
./configure CC=arm-linux-gcc --prefix=/opt/madplay_source/build --host=arm-linux --disable-debugging --disable-shared --enable-static CPPFLAGS=-I/opt/madplay_source/build/include LDFLAGS=-L/opt/madplay_source/build/lib
4 make
arm-linux-gcc -DHAVE_CONFIG_H -I. -I. -I. -DFPM_ARM -DASO_INTERLEAVE1 -DASO_IMDCT -I/opt/madplay_source/build/include -Wall -O -fforce-mem -fforce-addr -fthread-jumps -fcse-follow-jumps -fcse-skip-blocks -fexpensive-optimizations -fregmove -fschedule-insns2 -fstrength-reduce -fomit-frame-pointer -MT version.lo -MD -MP -MF .deps/version.Tpo -c version.c -fPIC -DPIC -o .libs/version.o
cc1: error: unrecognized command line option "-fforce-mem"
make[2]: *** [version.lo] 错误 1
如果此时make，make install就会报错，说是"-fforce-mem"参数不能识别。不知道是什么原因，然后就在网上查了一通，好像说是我机器环境的gcc版本（我的是gcc 4.3.2）过高导致的，所以不能识别其中的"-fforce-mem"参数选项，真是搞不懂，版本高还识别不了。。。
于是乎就打开当前目录下的Makefile文件，去掉里面出现的"-fforce-mem"，然后再make，make install就OK了
5
6 make install
四 编译madplay-0.15.2b
1 tar -zxvf madplay-0.15.2b.tar.gz
2 cd madplay-0.15.2b
3 ./configure CC=arm-linux-gcc --host=arm-linux --prefix=/opt/madplay_source/build --disable-debugging --disable-shared --enable-static CPPFLAGS=-I/opt/madplay_source/build/include LDFLAGS=-L/opt/madplay_source/build/lib
4 make
5 make install
五
1 将build/bin/下的madplay 改名为my_madplay
2 优化
arm-linux-readelf -d my_madplay
Dynamic section at offset 0x24ef8 contains 28 entries:
Tag Type Name/Value
0x00000001 (NEEDED) Shared library: [libid3tag.so.0]
0x00000001 (NEEDED) Shared library: [libm.so.6]
0x00000001 (NEEDED) Shared library: [libc.so.6]
0x0000000f (RPATH) Library rpath: [/opt/madplay_source/build/lib]
0x0000001d (RUNPATH) Library runpath: [/opt/madplay_source/build/lib]
将需要的库拷贝到开发板上
libm.so.6，libc.so.6在busybox制作根文件系统是已经生成在/lib目录下了，所以只要将/opt/software/madplay/build/lib目录下的libid3tag.so.0文件拷到/lib目录下即可
3 cp * /opt/rootfs/sound_bin/ -a
ll sound_bin/lib
