(gdb) c
The program is not being run.
(gdb)
There is NO WARRANTY是什么问题。。我用apt-get install gdb重新下gdb也是这个问题，但是用gdb的前端insight调试却可以，这是怎么回事？

The program is not being run.
Type r to run it.
(gdb) r
Type r to run it.
(gdb) r

它不是已经提示你程序还没有运行么，需要运行后才能运用 c 命令嘛
你可以先 br main，然后 r，接着 list 貌似就能看到调试的源码信息了吧...

gcc -g -o test test.c
gdb -q ./test
(gdb) l
然后打上断点，然后
(gdb) r
gdb -q ./test
(gdb) l
然后打上断点，然后
(gdb) r
