我得到了gdb brew install gdb.

源文件内容是:

#include <cstdio>
int main(){
    int a = 10;
    for(int i = 0; i< 10; i++){
        a += i;
    }
    printf("%d\n",a);
    return 0;
}

这是名为'demo'的可执行文件:https: //pan.baidu.com/s/1wg-ffGCYzPGDI77pRxhyaw

我像这样编译源文件:

c++ -g -o demo demo.cpp

并运行gdb

gdb ./demo

但是,它无法奏效.它无法识别可执行文件.
