我对gdb有些麻烦.这是我在名为main.cpp的单个文件中的代码

#include <iostream>

void myfunc();

int main(){
    char msg[] = "Hello World!";
    myfunc();

    std::cout << msg << std::endl;

    return 0;
}

void myfunc(){
    int boo = 16;
}

我用这个命令来编译这段代码:

g++ -g -Wall main.cpp -o foo

接下来,我使用了gdb:

$ gdb foo
(gdb) start
Temporary breakpoint 1 at 0x80487c3
Starting program: /home/laptop/workspace/foo 

Temporary breakpoint 1, 0x080487c3 in main ()
(gdb) s
Single stepping until exit from function main,
which has no line number information.
Hello World!
