Online GDB is online compiler and debugger for C/C++. You can compile, run and debug code with gdb online. Using gcc/g++ as compiler and gdb as debugger. Currently C and C++ languages are supported.
这里需要开启内核参数CONFIG_DEBUG_INFO和CONFIG_GDB_SCRIPTS。GDB 提供了 Python 接口来扩展功能,内核基于 Python 接口实现了一系列辅助脚本,简化内核调试,开启CONFIG_GDB_SCRIPTS参数就可以使用了。 Kernel hacking ---> [*] Kernel debugging Compile-time checks and compiler options ---> [*] Compile the ...
Line 6 of "test.cpp" starts at address 0x80483f5 and ends at 0x80483f7. (gdb) info line main Line 4 of "test.cpp" starts at address 0x80483ed and ends at 0x80483f0 . 7.3 disassemble 显示某个函数或某函数中一段代码的汇编 语法如下: disassemble disassemble [Function] disassemble [A...
利用相同的方法也可以很容易的获取类型T的字符串名称. 在rtti开启的情况下, 功能直接可获取...但不难发现, 这种方法也存在以下问题: 首先是依赖rtti, 在一些rtti关闭的情况下, 对应机制就停摆了 很重要的一点, 这是一个runtime实现, 也就是说, 天生与constexpr无缘, 我们没有办法做任何善于...c...
Debug Compilation NVCC, the NVIDIA CUDA compiler driver, provides a mechanism for generating the debugging infor- mation necessary for CUDA-GDB to work properly. The -g -G option pair must be passed to NVCC when an application is compiled for ease of debugging with CUDA-GDB; for example, ...
C++, Java, and Python are among the programming languages that are accepted. Simply go to the "Language" pull-down menu on the right side of the command bar and choose your chosen coding language. In addition to the language selection function, the OnlineGDB compiler has other options that ...
在gdb中输入命令apropos lx,没有任何输出,说明无法调用python辅助函数。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 (gdb) apropos lx 从stackoverflow网站上找到一篇文章gdb-lx-symbols-undefined-command,里边提到: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 gdb -ex add-auto-load-safe-path...
本文假设你能使用简单的unix/linux命令并能用gcc(GNU C Compiler, GNU C 语言编译器)编译程序,当然有编程经验更好。:) 为帮助你理解和操作,我将使用我遇到过的真实事例来演示使用gdb调试有缺陷(bug)的程序过程,你看过这篇笔记后能自己动手练一下最好。
