gdbserver 问题

Question

在arm板子上运行gdbserver, pc上运行arm-linux-gdb

pc上的信息：

list, break, continue, next 都可以用，但是也有一些错误信息。
run调试时肯定是要用的，弄了两天也没搞定，请各位高手帮忙

Answer 1

就是不能用run运行，只能用continue运行，但是这样又不能带参数，无法传递参数。难道非要把程序参数写死才能调吗？有没有更好的办法，急啊，请各位不吝赐教！！先行谢过了

Answer 2

急啊，老是用printf调试，要经常传程序，废时间，另外要看大的structure，也不可能用print一个个看成员啊，就算用全局变量，无法让程序停在线程里的某个点，还是没用。到底怎么弄多线程呢

Answer 3

用c是可以，把参数写死可以单步调，但是step多步就会出问题，而且无法调试多线程，一运行到创建新线程，程序就收到信号跳出。普通的gdb是可以调多线程的啊

Answer 4

不用r， 用c 应该可以

Answer 5

好像gdbserver确实不能用run, 可是continue不能加参数啊，难道要改源程序，写死参数？
