Hi Alexander,

You probably still need to generate and link with the dictionary for the
class 'vector<D_Line>'.

Cheers,
Philippe.

Subject: [ROOT] Problems using stl-vector


Hello rooters,

I have some problems with using the stl-vector.

I created a class 'Test' with the following methods:

 int foo(void);
 vector<D_Line> dLines;

where 'D_Line' is a class containing only 'normal' variables (onlt floats
and bools, no pointers or other objects).
The method 'foo' looks like this:


int Test::foo(void)
{

  D_Line dLine;
  dLine.setPosition(100);
  dLines.push_back(dLine);

  dLine.setPosition(200);
  dLines.push_back(dLine);

}

Now I call this method like this:

> #include "Test.cc"
> Test a;
> a.foo();

After that I try to clear the vector like this:

> dLines.erase(dLines.begin(),dLines.end());

But this does not work!
When I do exactly the same without using it in the ROOT-System it works!

So it seems that classes which are used by root cannot use the standard
'vector'-class.
So what can I do??
