<--! 强烈建议不要在虚拟机挂接Windows共享目录下进行编译 -->
1.配置编译环境
首先,将要使用的交叉编译器设为默认交叉编译器
然后,在libid3tag-0.15.1b、libmad-0.15.1b、madplay-0.15.2b、zlib-1.2.3这四个文件夹的同一目录建一个文件夹(例如libz),作为存放所生成文件的地方。
以下用目录/root/madplayer/libz 作为例子,
2.编译zlib-1.2.3
./configure --prefix=/root/madplayer/libz
打开生成的Makefile, (没有CC等options...)
修改CC(例如cc=arm-linux-gcc)
修改AR(例如AR=arm-linux-ar rcs)
修改RANLIB (例如RANLIB=arm-linux-ranlib)
如果之前编译过,先 make distclean 把上次的编译结果清除
make
make install
3.编译libid3tag-0.15.1b
首先,zlib-1.2.3编译完成后,才能进行此编译
./configure --prefix=/root/madplayer/libz --host=arm-linux --disable-shared CC=arm-linux-gcc
CPPFLAGS=-I/root/madplayer/libz/include LDFLAGS=-L/root/madplayer/libz/lib
(欲知上述options详情 请./configure --help)
make
make install
4.编译libmad-0.15.1b
./configure --prefix=/root/madplayer/libz CC=arm-linux-gcc --host=arm-linux --disable-shared
make
make install
5.编译madplay-0.15.2b
./configure --prefix=/root/madplayer/libz CC=arm-linux-gcc --host=arm-linux --disable-shared --enable-static
CPPFLAGS=-I/root/madplayer/libz/include LDFLAGS=-L/root/madplayer/libz/lib
make 在madplay-0.15.2b目录下面生成madplay的可执行文件
7.编译中,可能遇到的问题:
error: libz was not found
*** You must first install zlib (libz) before you can build this package.
*** If zlib is already installed, you may need to use the LDFLAGS
*** environment variable to specify its installed location, e.g. -L
.
没有正确配置编译好zlib,参考步骤2。(如仍未通过,请查看是否使用Windows共享的目录,若是,换到其他本地目录再试)
最后编译出来的mdaplay 在开发板上运行时出现如下所示的提示:
madplay: error while loading shared libraries: cannot open shared object file: cannot load sharedobject file: No such file or directory
则是因为在编译时没有设置好静态链接和共享库,正确的配置就是在编译libid3tag、libmad 和madplay 时,加上disable-shared 选项,同时(只)在madplay 的配置语句上加上enable-static设置为静态。

我用到的配置命令:
./configure --prefix=/work/tmp
./configure --prefix=/work/tmp --host=arm-linux --disable-shared CC=arm-linux-gcc CPPFLAGS=-I/work/tmp/include LDFLAGS=-L/work/tmp/lib
./configure --prefix=/work/tmp CC=arm-linux-gcc --host=arm-linux --disable-shared
./configure --prefix=/work/tmp CC=arm-linux-gcc --host=arm-linux --disable-shared --enable-static CPPFLAGS=-I/work/tmp/include LDFLAGS=-L/work/tmp/lib
