Custom plug-in

[ICT4Health]

Hello,
I need to develop a plug-in for a custom sensor. I have a development licence.

I followed the tutorial for the Visual Studio setup here:
http://docs.worldviz.com/vizard/#Usi...20SDK%7C_____2

Then I created a simple code that do nothing with the informations at this link:
http://docs.worldviz.com/vizard/#Ext...20SDK%7C_____3

So at the end I created two files:

MyExtension.h

#include <viz/Extension>
 
class MyExtension : public viz::Extension
{
public:
    MyExtension(void);
 
    virtual const char* getName() const { return "My Extension"; }
 
protected:
    
	virtual ~MyExtension(void);
};

MyExtension.cpp

#include "MyExtension.h"

extern "C" __declspec(dllexport) viz::Extension* CreateVizardExtension(viz::Data &data)
{
    return new MyExtension();
}

MyExtension::MyExtension(void) : viz::Extension()
{
}

MyExtension::~MyExtension(void)
{

}

Then I geneerated the MyExtension.dle and tried to load it with Vizard 5 with the following code

import viz
viz.go()
mysensor = viz.add('MyExtension.dle')

The result is the error:

ERROR: Failed to load plug-in: 'MyExtension.dle'

What am I missing?
