Test program for software defined radio USRP X310 - c++

Question

I want to run the first test program for my software defined radio USRP X310 which is given on the company's website: https://kb.ettus.com/Getting_Started_with_UHD_and_C%2B%2B
I work with Visual Studio 2015 on Windows. I have installed, build and linked in VS2015 the boost and UHD libraries (UHD version 3.10.1.1 and boost version 1.63.0).
Trying to debug the program I get several error messages about 'unresolved external symbols'. I tried to locate the problem and ended up with very basic code example and noticed that the function 'uhd::usrp::multi_usrp::make(device_args)' does not work. In addition 'uhd::set_thread_priority_safe()' does not work either.
It seems to me that the code itself is not the problem. Does anyone know where these errors come from?
My code
#include <uhd/utils/safe_main.hpp>
`#include <uhd/usrp/multi_usrp.hpp>`
`#include <uhd/utils/thread_priority.hpp>`
`#include <csignal>`
`#include <iostream>`
int UHD_SAFE_MAIN(int argc, char *argv[]) {
uhd::set_thread_priority_safe();
std::string device_args("addr=192.168.10.2");
uhd::usrp::multi_usrp::sptr usrp = uhd::usrp::multi_usrp::make(device_args);
return 0;
}
Error messages (I am sorry that they are German. I translated them which is written in brackets):
Fehler (error) LNK2019 Verweis auf nicht aufgelöstes externes Symbol (link

this problem comes if you want to build it in Debug-Mode. The UHD you are linking to are build for Release-Mode, so you have to build your project in Release-Mode too. I had the same problem, and now i'm trying to build the UHD for VS2015 in Debug and Release mode, to be able to link in Debug-Mode, to the Debug-Objects and in Release-Mode to Release-Objects. But i don't get it build in Debug neither in Release-Mode with this TUT (https://kb.ettus.com/Building_and_Installing_the_USRP_Open_Source_Toolchain_(UHD_and_GNU_Radio)_on_Windows). I have to look for this. IF you will get it to work, it would be nice if you can tell how you have done it ( I'm german too).
Hope this helps you, even your post is 6 months old :D.
