Error in new Project SDK R3

idata — Fri, 03 Feb 2017 11:21:03 GMT

Hi,

I'm new with the Intel SDK R3. I have an SR300 camera and I want to prove some code on it. I'm trying to create my own project based on the sample 'CameraViewer.cpp' and it doesn't work.

The error that appears is "LINK2001 external symbol PXCSession_CreateFromPath unsolved".

The code I put in the new project is this one:

# include

# include "RealSense/SenseManager.h"

# include "RealSense/SampleReader.h"

# include "util_cmdline.h"

# include "util_render.h"

# include

using namespace Intel::RealSense;

int wmain(int argc, WCHAR* argv[]) { //int main()// int wmain() //int main()//

/* Creates an instance of the SenseManager */

SenseManager *pp = SenseManager::CreateInstance();

if (!pp) {

wprintf_s(L"Unable to create the SenseManager\n");

return 3;

}

return 0;

}

Can anyone help me?

Thanks in advance,

One of the causes of the LNK2001 compiler error can apparently be when you are asking the program to look for something that does not exist. I'll do my best to work through possible causes with you.

The first thing I would try is to remove the line # include , as this is apparently a legacy instruction related to old MS-DOS compiler programs and is not needed by modern C compilers and is not part of the C standards.

Thanks for the answer!

I remove that line and It's still not working... I have another error (that appears before too)

-LNK2001 external symbol PXCSession_CreateFromPath unsolved

-LNK11201 1 external unsolved

Are you using a C# compiler? There is apparently no need for includes in the C# language - they are used in C and C++ languages.

Confirmed: CameraViewer.cpp is a C++ program. There does not seem to be a C# version of it.

https://software.intel.com/sites/landingpage/realsense/camera-sdk/v2016r3/documentation/html/sample_camera_viewer_cpp.html Sample: CameraViewer [C++]

This is fine if you are using a C++ compiler. If you are trying to use this listing in a C# compiler though, it would be like trying to run Windows programs on an iPhone.

I've created a new project based on C++ in Visual Studio, so I think I'm using a right compiler.

Ok, that's good to know. A couple of people fixed that error just by creating a new project file and copy-and-pasting their listing into the new project file. So that quick test may be worth trying.

Sorry, maybe I'm goint to make a fool question but, what do you mean about "their listing"?

There's no such thing as a silly question. I mean copying and pasting their program code.

I went back to my copy of the old RealSense PDF 'Getting Started' manual from 2014 and found this C++ code listing that creates the SenseManager like you are trying to do.

# include

# include "pxcsensemanager.h"

int wmain(int argc, WCHAR* argv[]) {

// create the PXCSenseManager

PXCSenseManager *psm=0;

psm = PXCSenseManager::CreateInstance();

if (!psm) {

wprintf_s(L"Unable to create the PXCSenseManager\n");

return 1;

}

// Retrieve the underlying session created by the PXCSenseManager.

// The returned instance is an PXCSenseManager internally managed object.

// Note: Do not release the session!

PXCSession *session;

session = psm->QuerySession();

if (session == NULL) {

wprintf_s(L"Session not created by PXCSenseManager\n");

return 2;

}

// query the session version

PXCSession::ImplVersion ver;

ver = session->QueryVersion();

// print version to console

wprintf_s(L" Hello Intel RSSDK Version %d.%d \n",ver.major, ver.minor);

// enumerate all available modules that are automatically loaded with the RSSDK

for (int i=0;;i++) {

PXCSession::ImplDesc desc;

if ( session->QueryImpl(0,i,&desc) < PXC_STATUS_NO_ERROR ) break;

// Print the module friendly name and iuid (interface unique ID)

wprintf_s(L"Module[%d]: %s\n",i,desc.friendlyName);

wprintf_s(L" iuid=%x\n",desc.iuid);

}

// close the streams (if any) and release any session and processing module instances

psm->Release();

system("pause");

return 0;

}

I've copied and pasted your code and compiled in my project and the same error appears... :/

Here is the page from the manual on setting up a RealSense C++ development environment. Please check it to see if you have done it all.

Ok, that was the mistake... now it works fine, thanks!
