Error 1097 while calling C++ DLL

[tushar.V]

Hi all,

I have created a C++ DLL for Labview, but it generates error 1097 for this part of code mgr.Open() and after that, below is my code

it works fine in visual studio.

#include "FpgaManager.h"

#include <iostream>

namespace fpgamgr = enclustra::fpgamanager;

int main()

{

fpgamgr::FpgaManager mgr(fpgamgr::types::ApiUrl:: FX3Default());

std::cout << "FPGA Manager Version: " << mgr.Details() << std::endl;

auto& mm = mgr.CreateMemoryMap(0);

mgr.Open();

std::cout << "Register: " << std::hex << mm.ReadRegister(0x10001000) << std::endl;

return 0;

}

Regards,

Tushar

The Call Library Node only can call exported standard C functions. It can not know about C++ object pointers nor any of the C++ object data types.

There are not only to many of them that the Call Library Node ever could support them, but the exact implementation of these things is compiler specific.

You need to write a wrapper DLL, that calls the C++ methods and exports standard C compatible functions with standard C compatible parameters.
