我想使用gdb和makefile脚本演示我的程序，但make不会在gdb之后执行更多命令

Question

这是我的makefile代码

all: ass3

ass3: ass3.asm
    nasm -f elf ass3.asm
    ld -m elf_i386 -s ass3.o -o demo
    echo Start debugging\n
    gdb demo
    echo Breakpoint after first case has been calculated\n
    b *0x804809e
    echo Printing 1st case answer\n
    i ecx
    echo Breakpoint after second case has been calculated\n
    b *0x80480ba
    i ecx
    echo Breakpoint on third case showing the execution path when the difference of time    is negative\n
    b *0x8048113
    echo Since Initial time is large than final time, it will jump to an error catcher\n
    r
    echo Program caught the error and terminated the program\n

binaries = demo

clean: 
    rm -f $(binaries) *~

当我键入make时，它在gdb上停止，当我按下“q”（退出）时，它只是继续执行回显，直到它停止在b * 0x804809e这是一个gdb命令

如何让我的makefile代码在gdb上运行演示？

Answer 1

gdb启动自己的提示，因此您无法直接与其进行交互。

它在启动后在启动时读取.gdbinit，因此您可以修改它以使其自动化。
