问题描述

我做错了（或没有做过） gdb 对我来说不正确吗？

what have i done wrong (or didn't do) that gdb is not working properly for me?

root@6be3d60ab7c6:/# cat minimal.c 
int main()
{
  int i = 1337;
  return 0;
}
root@6be3d60ab7c6:/# gcc -g minimal.c -o minimal
root@6be3d60ab7c6:/# gdb minimal
GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1

推荐答案

如果使用的是Docker，则可能需要-security-opt seccomp = unconfined 选项（以及启用ptrace）：

If you're using Docker, you probably need the --security-opt seccomp=unconfined option (as well as enabling ptrace):

docker run --cap-add=SYS_PTRACE --security-opt seccomp=unconfined
