求前辈，高手指教

参考技术A 这是汇编代码啦，你应该用汇编交叉编译的，估计你用错了编译工具，所以才有这么多错误信息。追问

用的是arm-linux-gcc4.4.3,配置就按网上的教程安装的，arm-linux-gcc -v,也显示了版本，安装方法

参考技术B 汇编用的是大写的.S 参考技术C 在你的 label 前面加上 . 看看。追问

唉，没用耶！

arm-linux-gcc交叉编译是静态编译还是动态的

参考技术A 动态的，你在后面加-static就是静态的 参考技术B 你得看这个编译器的configure是啥

如果没有特殊参数，默认都是动态编译

没有依赖的动态库当然不能运行本回答被提问者采纳
