gdb (gdb) run Starting program: /path/to/example Breakpoint 1, main () at example.c:5 5 int a = 5; 单步执行 使用next(或简写为n)命令来单步执行下一行代码(但不会进入函数内部)。如果要进入函数内部,请使用step命令。 gdb (gdb) next 6 int b = 10; 查看变量值 使用print(或简写为p)命...
Next, launch the program with GDB as: $ gdb loop Once in GDB, we can run the program by using the run or r command. You can stop the program while it's running by using the CTRL + C key. Let us set a breakpoint at the main function to halt the execution at that point. In ...
First, the operating system doesn’t know how to run an object file, and second, you likely need to combine several object files and some system libraries to make a complete program. 目标文件是处理器几乎可以理解的二进制文件,只是还有一些松散的部分。 首先,操作系统不知道如何运行目标文件,其次,你...
Save the program in a file with the name loop.c • 2. Step: Build an executable. Use the GCC with the parameter –g. This parameter tells the GCC to place debugging information's within an executable code file. gcc –g –o loop loop.c • 3. Step: Run GDB. The debugger needs...
Question: I was debugging a program with gdb debugger. When I tried to print the value of a variable while tracing a function call, gdb says <value optimized out>, not displaying the value. How can I show the value of an <optimized out> variable in gdb?

You can debug a C++ program using a GNU* Debugger (GDB*) or by printing the values to the terminal. For kernel and device code, use GPU debugging. You have three options: Output stream method Experimentalprintfmethod Using the Intel® Distribution for GDB* ...

然而,如果遇到不同架构的二进制文件,比如 aarch64 架构,应如何方便地进行调试和模拟运行呢? 一种常见的方法是在相应架构上启动gdbserver或使用frida等类似工具进行跟踪。但这种方法过于笨重。是否存在一种更轻量级的方法来模拟运行这个 ELF 文件呢? unicorn模拟运行,...
