这个问题我也碰到过，编译之前运行一句：
export LD_LIBRARY_PATH=/usr/local/arm/2.95.3/arm-linux/lib:$LD_LIBRARY_PATH
应该就OK了
拷贝C 库
交叉应用程序的开发需要用到交叉编译的链接库，我们在移植应用程序到我们的目标板的时
候，需要把交叉编译的链接库也一起移植到目标板上，这里我们用到的交叉工具链的路径是
/usr/local/arm/...../,链接库的目录是/usr/local/arm/...../arm-linux/lib，将其中部分库文件及符号链接拷贝到root_nfs(你创建的busybox的根目录）文件夹下的lib文件夹中。
部分库文件及符号链接有：ld-2.3.2.so,ld-linux.so.2,libc-2.3.2.so,libc.so.6
