Sourcery_G++_Lite   2009.q3版 4.3.3
在虚拟机上写了一个helloworld程序, 用它的交叉编译器编译, 可以在目标板运行, 
把它的gdbserver和 helloworld拷贝到目标板

看资料都是先在目标板上运行gdbserver, 然后在虚拟机上运行gdb进行调试
于是在开发板上我敲 
gdbserver "PC的IP":1234 HELLOWORLD

此时报很多错, 最后helloworld居然还执行了起来, 按我的理解, 这里只是服务器, 运行应该在pC上才是啊

附:出错信息

去下一个最新的gdb和gdbserver,交叉编即可,很容易.

开发板上跑gdbserver, 开发机的linux上跑和gdbserver版本一致的gdb.

gdbserver环境配置好没有？
