Calling to C++ function external library
Is possible calling a C++ function external library from NSIS. This library is made for me.

Thanks for all.

Use the System plug-in.

For example, If I create a static library named stlib.lib with these source code:

// MathFuncsLib.h

namespace MathFuncs
{
    class MyMathFuncs
    {
    public:
        // Returns a + b
        static double Add(double a, double b);
    }
}

--------------------------------
MathFuncsLib.cpp
--------------------------------
#include "MathFuncsLib.h"

#include <stdexcept>

using namespace std;

namespace MathFuncs
{
    double MyMathFuncs::Add(double a, double b)
    {
        return a + b;
    }
}

In my opinion, since I've been away from nsis for some time, you can't call class methods from nsis... I can be wrong.... there are code that can call C# functions, you might want to check them...
I guess you can create a static function and create a instance of your class.
There are tutorials about how to use system plugin, search them :)

Do you advise me that developing a C library (.lib or .dll) is better, instead of a C++ library?

Thanks for all.

You might be able to get C++ to work, but C is way simpler. You could also write simple C wrapper for your C++ classes that only NSIS will use.
