MSB3073 exited with code 1 error

[injo Kang]

Hi. I’m using ‘Assembly Tobii EyeX Development kit’ and C/C++ SDK about it, because i want to develop program with ‘EyeX’.

I tried to use the Tobii EyeX SDK and follow the instruction in below link
“http://developer.tobii.com/walkthrough-setting-cc-project-eyex-c-api”

But, I got a problem that

Error MSB3073 The command “copy /b /y C:\Users\kang-injo\Downloads\TobiiEyeXSdk-Cpp-1.7.489\lib\x64\Tobii.EyeX.Client.dll C:\Users\kang-injo\Documents\Visual Studio 2015\Projects\ConsoleApplication5\x64\Debug\
:VCEnd” exited with code 1. ConsoleApplication5 C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppCommon.targets 133

I think the file can’t find ‘Tobii.EyeX.Client.dll’.

How can I solve this problem?

Thank U,
Injo

Hi @benedict78,

A couple of things to check here: Your output path looks a little strange with the “:VCEnd” at the end of the line, I would double check that.

You could also try placing the MsBuild “Copy” task in an AfterBuild target over a post-build event.

Append this Target into your project file and remove the PostBuildEvent.

<Target Name="AfterBuild">
    <Copy SourceFiles="C:\Users\kang-injo\Downloads\TobiiEyeXSdk-Cpp-1.7.489\lib\x64\Tobii.EyeX.Client.dll" 
          DestinationFolder="C:\Users\kang-injo\Documents\Visual Studio 2015\Projects\ConsoleApplication5\x64\Debug\" 
          OverwriteReadOnlyFiles="true" 
          SkipUnchangedFiles="false" />
</Target>

Might also be worth ensuring you are running as administrator. I assumed you double checked the existing of the source DLL in the path you specified?

Hi Grant ! Thx for ur help!
And then I got another problem.
I want to print “Success” if Tobii is connected to my C++ file.
But it always prints “Fail”.
How can I solve this?

#include “stdafx.h”
#include <eyex\EyeX.h>
#include <iostream>

#pragma comment (lib, “Tobii.EyeX.Client.lib”)
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
if (TX_RESULT_OK != txInitializeEyeX(TX_EYEXCOMPONENTOVERRIDEFLAG_NONE, NULL, NULL, NULL, NULL))
{
cout << “Success” << endl;
return -1;
}
cout << “Fail” << endl;
return 0;
}

Thank you

Hi, I suspect the error lies in the line:

if (TX_RESULT_OK != txInitializeEyeX(TX_EYEXCOMPONENTOVERRIDEFLAG_NONE, NULL, NULL, NULL, NULL))

Did you try just running a test calibration? You could also try a different route by testing
for user presence:

// Print value of user presence state if it is valid
var userPresence = _eyeXHost.UserPresence;
if (userPresence.IsValid)
{
Console.WriteLine("User presence: {0}", userPresence.Value);
}
// Subscribe to changes in the user presence state.
eyeXHost.UserPresenceChanged += MyEventHandler;

If the EyeX Engine is not connected, user presence and all other states will be set to invalid.
