I decided to strip down the code in sysinfo, and go after only the pieces of information that I really want, so I wrote a small program, but I get a link error when I try and run it.

My code is a simple window with a push button on it to execute the code.

The main code is as follows which is copied directly from the sysinfo demo:

#include "mysysinfo1.h"

using namespace Upp;

#include <SysInfo/SysInfo.h>

static bool end = false;

void mysysinfo1::Gettheinfo()
{

String manufacturer, productName, version, mbSerial;
Date releaseDate;
int numberOfProcessors;
GetSystemInfo(manufacturer, productName, version, numberOfProcessors, mbSerial);

// romptOK("Hello world");

PromptOK(mbSerial);

PromptOK(GetDesktopFolder());
}

mysysinfo1::mysysinfo1()
{
CtrlLayout(*this, "My System Information program");

// add below for using a button
btnDoSomething <<= THISBACK(Gettheinfo);

}

GUI_APP_MAIN
{
mysysinfo1().Run();
}

And the error that I am getting on it is
