Set up a C++ project in VS2017 from scratch

JAlli3 — Sat, 02 Mar 2019 01:36:16 GMT

Hi, as the title says, I'm trying to set up a project in from scratch without success. I've downloaded the latest SDK from GitHub and can get the examples running no problem. I'm using a C++ toolkit called openFrameworks and need to integrate the SDK into an existing project.

So far I've added librealsense-2.18.1\include\librealsense2 to the C/C++ -> Additional Included Directories and pointed to librealsense-2.18.1\Build\Release in the Linker -> Additional Library Directories to connect to the realsense2.lib file.

I've tried some of the code from this page - https://github.com/IntelRealSense/librealsense/tree/master/examples/capture

But pipe.start(); leads to lots of unresolved external symbol errors e.g:

Error - LNK2001 - unresolved external symbol _rs2_get_failed_function - ofxIntelRealSense.obj

What do I have to link to in order to get started? All I need to do is get the depth texture from 2 cameras.

Details:

Windows 10 with VS2017

RealSense D435 with latest firmware

SDK 2.18.1 downloaded from GitHub

This is a subject that admittedly is not explained in a beginner-friendly way. I should mention that I do not usually do project building in Visual Studio (the Unity game engine is my primary development environment), but I will do my best to assist.

I believe that in RealSense SDK 2.0, Librealsense is linked in to a Visual Studio project via a program called CMake. The links below may be helpful in understanding this process.

Thanks for your reply. It seems like the only thing I was missing was the following in my RealSense class:

#pragma comment(lib, "realsense2.lib")

Not sure why this is necessary. I thought that linking to the correct directory was enough.

Is your project linking to the RealSense library correctly now, please?

Yes it is. See my above post for the solution. Thanks again, I appreciate your response.
