我的gdb为什么不能正常运行?

我的gdb为什么不能正常运行?
我的 GDB 不会 RUN ???
我的 GDB 装在sun solaris 7 下，一切设置妥当，我开始写了个
自己的小程序，很简单。
文件名 ： myc.c

#include <stdio.h>
int main()
{ int i;
i=1;
i=2;
printf("Hello World!\n");
return 0;}

我用gcc 对它进行编译 gcc -g -o myc myc.c
当前目录下生成了可执行的 myc
输入命令 myc
#myc
Hello World
#

输出结果正确.

可是我用gdb 载入它时, gdb myc
结果如下

(gdb) run
Starting program: /export/home/guo/DataStr/myc
/proc/577/ctl: Inappropriate ioctl for device
/proc/577/status: No such file or directory.
can't open process file
(gdb)
注意,我运行了 run 命令,可是它却报这种错,为什么会这样?? 如何才可以调试??
