Ubuntu8.10下移植madplay 时怎么设置 LDFLAGS 环境变量？急！！！

*** You must first install libmad before you can build this package.
*** If libmad is already installed, you may need to use the LDFLAGS
*** environment variable to specify its installed location, e.g. -L<dir>.
root@ubuntu:/opt/FriendlyARM/QQ2440/madplay/src-x86/madplay-0.15.2b#

几个压缩包都安装好了，就是到了这一步没有办法向下进行
按照手册（如下）
#cd ../src-x86/madplay-0.15.2b
#./configure --prefix=/opt/FriendlyARM/QQ2440/madplay/target-x86 --CPPFLAGS=-I/opt/
FriendlyARM/QQ2440/madplay/target-x86/include --LDFLAGS=-L/opt/FriendlyARM/QQ
2440/madplay/target-x86/lib

可根本就不正确
弹出以下错误
configure: error: unrecognized option: --CPPFLAGS=-I/opt/FriendlyARM/QQ2440/madplay/target-x86/include
Try `./configure --help' for more information.

去掉CPPFLAGS以及LDFLAGS前面的'--',它们是环境变量而不是configure的参数.用./configure --help可以查看完整的参数用法

上面的方法试过了，还是不可以，又回到了设置CPPFLAGS环境的地方
configure: error: mad.h was not found
*** You must first install libmad before you can build this package.
*** If libmad is already installed, you may need to use the CPPFLAGS
*** environment variable to specify its installed location, e.g. -I<dir>.
root@ubuntu:/opt/FriendlyARM/QQ2440/madplay/src-x86/madplay-0.15.2b#

所缺少的mad.h应该是libmad提供的.你需要先编译它.

我在编译libmad的时候，使用手册上面的指令
#cd ../ libmad-0.15.1b
#./configure --prefix=/opt/FriendlyARM/QQ2440/madplay/target-x86
#make
则结果如下
#./configure --prefix=/opt/FriendlyARM/QQ2440/madplay/target-x86
#make
出现以下错误

如果使用指令
./configure CC=/usr/local/arm/3.4.1/bin/arm-linux-gcc --host=arm-linux --prefix=/opt/FriendlyARM/QQ2440/madplay/target-x86 --disable-shared

make
则不会报错，而且include 和lib 文件夹里面有相应的编译结果文件(结果和手册上面说的一样)


我不知道，我到底有没有编译成功～～～～～～～～～～～～

大哥,一个用的是Ubuntu的gcc-4.x,编译出的是x86的二进制档;一个是3.4.1的交叉编译器,生成的是开发板用的ARM二进制档.根本不是同一回事好吗
