gdb调试stl

GDB中print方法并不能直接打印STL容器中保存的变量，其实只要http://www.yolinux.com/TUTORIALS/src/dbinit_stl_views-1.03.txt这个文件保存为~/.gdbinit  就可以使用它提供的方法方便调试容器

 

source ~/.gdbinit

 Data type   GDB command
 std::vector    pvector stl_variable
 std::list  plist stl_variable T
 std::map pmap stl_variable
 std::multimap    pmap stl_variable
 std::set   pset stl_variable T
 std::multiset  pset stl_variable
 std::deque pdequeue stl_variable
 std::stack pstack stl_variable
 std::queue pqueue stl_variable
 std::priority_queue    ppqueue stl_variable
 std::bitsettd>  pbitset stl_variable
 std::string pstring stl_variable
 std::widestring pwstring stl_variable

 

 

如正常我使用GDB自带的print打印一个STL list容器变量list

 (gdb) p lst
 $4 = {
   <std::_List_base<int, std::allocator<int> >> = {
     _M_impl = {
       <std::allocator<std::_List_node<int> >> = {
         <__gnu_cxx::new_allocator<std::_List_node<int> >> = {<No data fields>}, <No data fields>},
       members of std::_List_base<int, std::allocator<int> >::_List_impl:
       _M_node = {
         _M_next = 0x804d008,
         _M_prev = 0x804d048
       }
     }
   }, <No data fields>}

 

 

现在我使用这个脚本提供的plist方法打印

 (gdb) plist lst
 List size = 5
 List type = std::list<int, std::allocator<int> >
 Use plist   to see the elements in the list.
 (gdb)

 

详细查看list中的元素信息

 (gdb) plist lst int
 elem[0]: $5 = 7
 elem[1]: $6 = 1
 elem[2]: $7 = 5
 elem[3]: $8 = 9
 elem[4]: $9 = 2
 List size = 5
 (gdb)
