[ZZ]配置GDB以支持查看stl容器数据

原文链接： http://www.cublog.cn/u1/44543/showart_1953788.html

1. 下载 http://www.yolinux.com/TUTORIALS/src/dbinit_stl_views-1.03.txt

2. #cat dbinit_stl_views-1.03.txt >> ~/.gdbinit

3. 若正处于gdb中，运行命令:

(gdb) source ~/.gdbinit

4. 例如，如下代码：

bugging.cpp

#include <vector> using namespace std; int main() { vector<int> vec; vec.push_back(2); vec.push_back(3); vec.push_back(4); return 0; }

编译：

#g++ -o bugging -g bugging.cpp

gdb调试：

# gdb bugging GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

5. 默认情况下gdb不能用[]查看stl容器的数据元素，提示如下错误：

(gdb) print vec[0] One of the arguments you tried to pass to operator[] could not be converted to what the function wants.
