Problem including files in ice files

Dears,

I'm trying to launch the following command:

slice2py -IDIR/usr/share/slice/ --ice VirtualReality.ice

but I get an error.

I have to include the <Ice/Identity.ice> file. It is located in the /usr/share/slice directory. But slice2py finds the following error:

error: Can't open include file "Ice/Identity.ice"
    #include <Ice/Identity.ice>

I'm not able to pass it to slice2py. I can't understand why.

#ifndef VIRTUALREALITY_ICE
#define VIRTUALREALITY_ICE

#include <Ice/Identity.ice>

module VirtualReality
{

const int nJoint = 7;
const int nCartesianDof = 6;

sequence<double> DoubleSeq;
const int DoubleSeqSize = 7;


interface CallbackReceiver
{
    void setEnvironment(string str);
    void setPosQuat(DoubleSeq seq);
};

interface GUIserver
{
    void addClient(Ice::Identity ident);
    void setProxy(CallbackReceiver* proxy);
    DoubleSeq getPosQuat();
    void startPosQuatStream();
    void stopPosQuatStream();
    void shutdown();
};

};

If I substitute

#include <Ice/Identity.ice>

with

#include </usr/share/slice/Ice/Identity.ice>

and call

slice2py --ice VirtualReality.ice

it works.


I can't understand why! Where am I wrong?

Thanks!
