1. 下载 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

( gdb) help pvector 
Prints std : : vector < T> information. 
Syntax: pvector < vector > < idx1> < idx2> 
Note: idx, idx1 and idx2 must be in acceptable range [ 0. . < vector > . size( ) - 1] . 
Examples: 
pvector v - Prints vector content, size, capacity and T typedef 
pvector v 0 - Prints element[ idx] from vector 
pvector v 1 2 - Prints elements in range [ idx1. . idx2] from vector
