先下载gdb_stl_utils., extract it, and run make. This will compile and install the necessary files in ~/.gdb (edit the Makefile if you want to use a different directory). To use the p_stl_* functions, add:
source ~/.gdb/gdb_stl_utils
to your ~/.gdbinit.
I've tested this with GCC 3.3.3 and 3.4.0, and GDB 6.0. Let me know if you have any problems with it!
如何使用请查看gdbint文件，里面描述得很详细。
注意：
比如打印vector：
1.(gdb) p vec
$1 = {
<std::_Vector_base<int,std::allocator<int> >> = {
_M_impl = {
<std::allocator<int>> = {
<__gnu_cxx::new_allocator<int>> = {<No data fields>}, <No data fields>},
members of std::_Vector_base<int,std::allocator<int> >::_Vector_impl:
_M_start = 0x92ec040,
_M_finish = 0x92ec058,
_M_end_of_storage = 0x92ec060
}
}, <No data fields>}
2.(gdb) p_stl_vector vec->_M_impl(_M_start和_M_finish位于_M_impl具体情况可能不同)
Vector Element 0: $2 = 0
Vector Element 1: $3 = 1
Vector Element 2: $4 = 2
Vector Element 3: $5 = 3
Vector Element 4: $6 = 4
Vector Element 5: $7 = 100

GDB的自定义命令非常有用，通过自定义命令，直接操作容器中的数据，可以方便的查看STL容器中的数据。
这个链接dbinit_stl_views是Dan C Marinescu写的查看STL容器的自定义命令（如果不适合你的STL版本的话，可以自行修改）。把它添加到你的.gdbinit中，就可以方便的查看STL容器了。它提供了查看vector，list，map，multimap，set，multiset，deque，stack，queue，priority_queue，bitset，string，widestring等对象的方法，非常好用！

- (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
- (gdb) break main
