1. 设置运行参数:通过“set args <arguments>”设置命令行需要的参数,比如程序需要一个输入文件/tmp/input.txt,则可以“set args /tmp/input.txt”。设置完成后可以通过“show args”命令查看当前设置的参数。 2. 设置运行环境: 通过“path ”设置可执行文件搜索路径,“show paths”显示当前配置。 通过“set env...
方式一:直接运行gdb,然后在gdb中执行“file a.out”加载程序。 方式二:gdb <program>,命令行给出可执行程序运行,即运行“gdb a.out” 方式三:gdb <program> <core_file>,带core文件运行,“gdb a.out /tmp/core-19475”(假设a.out运行产生了/tmp/core-1975的core dump文件) 方式四:gdb <program> <pid...
假设我们有以下的C++代码: #include <iostream>int main() {std::cout << "Start of the program." << std::endl;std::cout << "This is a test." << std::endl;std::cout << "End of the program." << std::endl;return 0;} 如果我们想跳过输出"This is a test."这一行,可以在GDB中...
