Vector templates not working on Solaris (Sun ONE Studio 8).

I just upgraded to Sun One Studio 8 Compiler Colleciton and I can't seem to get vector working.  Here is a little test program:

#include <vector>

int main() {
        printf ("Just testing the vector include...\n");
        vector<int> v;
        return 0;
}

And here is what happens:

[root@usfrssa9 vector]# uname -a
SunOS usfrssa9 5.9 Generic sun4u sparc SUNW,Sun-Blade-100
[root@usfrssa9 vector]# /opt/SUNWspro/bin/CC -V
CC: Sun C++ 5.5 2003/03/12
[root@usfrssa9 vector]# /opt/SUNWspro/bin/CC vector.cpp
"vector.cpp", line 5: Error: vector is not defined.
"vector.cpp", line 5: Error: Badly formed expression.
2 Error(s) detected.

Am I missing something?  I looked for the vector include file and found two:
[root@usfrssa9 vector]# find /usr/include /opt/SUNWspro -name vector -print
/opt/SUNWspro/prod/include/CC/Cstd/vector
/opt/SUNWspro/prod/include/CC/stlport4/vector

I tried adding each of these to the include path but that didn't help.

You need to specify the 'std' namespace or explicitly point out that you're referring to 'std::vector', e.g.

#include <vector>
using namespace std;

int main() {
        printf ("Just testing the vector include...\n");
        vector<int> v;
        return 0;
}
or

#include <vector>

int main() {
        printf ("Just testing the vector include...\n");
        std::vector<int> v;
        return 0;
}

BTW, the 1st approach will save a lot more typing :o)

Ok, that worked!  Why is it that the man page posts an example without doing this?

EXAMPLE
     //
     // vector.cpp
     //
     #include <vector>
     #include <iostream>

     ostream& operator<< (ostream& out,
     const vector<int, allocator>& v)
      {
      copy(v.begin(),v.end(),ostream_iterator<int,char>(out,"
      "));
      return out;
      }
     int main(void)
      {
     // create a vector of doubles
        vector<int>         vi;
       int                 i;

     for(i = 0; i < 10; ++i) {
        // insert values before the beginning
       vi.insert(vi.begin(), i);
        }

     // print out the vector
     cout << vi << endl;

     // now let's erase half of the elements
     int half = vi.size() >> 1;
     for(i = 0; i < half; ++i) {
       vi.erase(vi.begin());
        }

     // print ir out again
     cout << vi << endl;

     return 0;
      }

Good question :o)

Either the man page is erroneos or simply outdated - maybe it was created before the C++ standard has been finalized...
