Hi,
I am trying to put an stl vector of floats in my tree, but I fail.

I am using Root version 3.10.01 as an external tool in my C++ program.

The syntaxes I have tried are

  tree->Branch("SizeSiStripRUs", "stl::vector<Float_t>", &SizeSRU);
Or 
  tree->Branch("SizeSiStripRUs", "vector<Float_t>", &SizeSRU);
Where:
  Ttree * tree;
  vector<Float_t> * SizeSRU;	

Both forms result into 

Error in <TTree::Bronch>: Cannot find class:stl::vector<Float_t>
or
Error in <TTree::Bronch>: Cannot find class:vector<Float_t>

I thought that stl vectors were fully supported in the Root version I
have used. Could anyone suggest what I am doing wrong. I searched the
web site, but I couldn't find anything explaining this point (I must
have surely not searched well enough)

Thanks in advance

Giacomo
