There's nothing wrong with that line provided that:

#include <vector>
#include <string>
using namespace std;

all appear before it in the file. If you could produce a minimal but
complete file that generates the error you're seeing and post it here it
would be much easier for someone to help you.

Thanks I add
use namespace std befoer this line and now it doesn't generate any error for
this line but I have error for the following lines:
line 67: typedef vector<string>::pointer pointer;
line 68: typedef vector<string>::const_pointer const_pointer;

the errors are:
c:\matlab701\toolbox\xilinx\sysgen\inclu

Error executing cl.exe.

the last warning is for the following line:

vector<string> _strings;

Any help?
Sorry I didn't writre any code with STL and hence very simple and foolish
questions!

The message states it rather clear, there is no member pointer in
std::vector defined. Maybe you could learn faster if you would first
read a book about the usage of STL-Templates.

Try this one:
http://www.informatik.hs-bremen.de/~brey/stlbe.html

It's a free downloadable translation from a german book about
STL. The translation is not too good, but it has an quite pragmatic
approach and as a starter it might be sufficent.

Carl asked, "If you could produce a minimal but
complete file that generates the error you're seeing and post it here it
would be much easier for someone to help you".

So where is your complete code example demostrating the problem?
