gdb输出stl-终结者

gdb中输出vector之类stl的方法可以用建立问价.gdbinit放在home下，

然而仍然不能输出嵌套的vector，下面的方法解决了这个问题

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()
To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N
Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start
And the GDB command to print N elements of an array starting at pointer P is:

print P@N
Or, in a short form (for a standard .gdbinit):

p P@N
