I am trying to build Vivek's Virtual Camera on Windows 10.
For that I need to have Win7Samples/multimedia/directshow/baseclasses
I have downloaded baseclasses and built it using Visual Studio 2019.
Now I am ready to build Virtual camera filter. I followed few requisite steps
git clone https://github.com/roman380/tmhare.mvps.org-vcam
cd tmhare.mvps.org-vcam\Filters
Then I tried to open Filters.dsp in Visual Studio 2019 which asked me to do one-way upgrade
Added C:\Users\alokm\tmp\Windows-classic-samples\Samples\Win7Samples\multimedia\directshow\baseclasses in Additional Include Directories
Added C:\Users\alokm\tmp\Windows-classic-samples\Samples\Win7Samples\multimedia\directshow\baseclasses\Debug to Addition Library Directories
After all these steps I tried to build by hitting Build >> Build Solution
But I am getting lot of linker errors.

Where I am wrong? How to make this working?
The problem building the project is coming from this:
The project source code has a dependency of DirectShow BaseClasses which is no longer a part of Windows SDK
The project has too many settings diverged from defaults; with current Visual Studio it becomes a problem
I updated the github repository and changed the project settings to make the project build (Visual Studio 2019 Communitty) and run: most of the C++ project settings are reverted and DirectShow BaseClasses are used in the build configuration from github.
Check out README.md there, follow build steps (which require to pull Windows SDK Samples first, and build DirectShow stuff there), have DLLs registered (regsvr32) and finally you will have the filter generating video with random data:

I was following this OpenGL tutorial on YouTube https://youtu.be/45MIykWJ-C4. but instead of following everything exactly, I tried to setup GLFW using premake. then I tried running with just the glfwInit() and received these errors

can anyone tell me why this happens? I tried following this tutorial before and it work for me perfectly but this time it didn't. I'm guessing this might be a problem with the OpenGL file itself, which causes it not to link properly. thanks!
I have a solution that is works, then I was needed to add a project that has implementation of MediaFoundation. So, in order to include it I added this project as existing one then in configuration in General section I provided path to .h files and then in Liker input added .lib
After this I tried to use it and write include in one of my files and then invoked a few methods from this project that was added.
When I tried to compile my project I got an errors :

First of all it is strange because I have already use this project in other solution and there weren't problems, but ok after a research I have found out that I need to add in configuration Linker -> input a few more .libs
Mf.lib
Mfplat.lib
mfuuid.lib
(inspire of I don't have these lines in my other solution where does it works) and after I added these lines a lot of error gone, but one left

And I have not found nothing about how to solve it. I am a relatively new in c++ and it looks weird that in order to make MediaFoundation(big lib) work I need to spend a few hours in order to find out what to add in additional in order to make it works.
So, question is - what am I missing here?
You need to include this :
#pragma comment(lib, "mfreadwrite")
Documentation usually helps :
MFCreateSourceReaderFromByteStream function

Please refer to Visual Studio 2017 and curlpp library LNK2019 error if you would like to see my configurations for my project.
I try to build cpp file using eclipse cdt. Linker throws "unresolved external symbol", however path to lib file that contains implementation for function is listed in LIB environment variable on Project properties->C/C++ Build->Environment
What am I doing wrong?
UPD I try to build file. There is lib RpcRT4.Lib on the path C:\Program Files\Microsoft SDKs\Windows\v7.0A\Lib\
And linker fails:

And environment settings for project
I'm not entirely clear on whether you've already done this based on the question, but just adding the directory to your linker's search path isn't enough for any compiler/linker I've ever used. There could be hundreds of different libraries in there, even different versions of the same library, and the linker has no idea which ones you do and don't want. You need to tell it, explicitly, to link against the library using the appropriate parameter.
It looks like you're using the Microsoft linker, which I've never used, so I can't help you with the specific flag but it should be easy enough to find what it is in the documentation if that's the issue. I presume Eclipse has a method of specifying this in the GUI as well which should be generic across the various compilers it supports.
