I'm trying to compile the example from here;
http://msdn.microsoft.com/en-us/library/ms682619(VS.85).aspx
I've installed the Platform SDK, but I'm getting these errors;
Error 1 error LNK2019: unresolved external symbol _GetDeviceDriverBaseNameW#12 referenced in function _main DriverChecker.obj DriverChecker
Error 2 error LNK2019: unresolved external symbol _EnumDeviceDrivers#12 referenced in function _main DriverChecker.obj DriverChecker
Error 3 fatal error LNK1120: 2 unresolved externals C:\Files\Projects\VS2008\DriverChecker\Debug\DriverChecker.exe DriverChecker
Anyone any idea how to get this compiling correctly?
You just need to add psapi.lib as an additional library in your linker options.
Edit properties for your project, navigate to Linker->Input, and type "psapi.lib" where it says Additional Dependencies.

I am trying to use the detours library in a visual studio empty windows project. I cloned the repository (https://github.com/microsoft/Detours), I added the include directory into Project Properties / C/C++ / Additional Include Directories, and I added the lib.X86 directory into Project Properties / Linker / Additional Library Directories. I get no errors visible on the file, but when I build I get
1>Source.cpp
1>Source.obj : error LNK2019: unresolved external symbol _DetourTransactionBegin#0 referenced in function _main
1>Source.obj : error LNK2019: unresolved external symbol _DetourTransactionCommit#0 referenced in function _main

1>Done building project "Project3.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped =========
Which looks like the library wasn't included correctly. How do I properly include the detours library into a visual studio project and what am I doing wrong?
You need to add the specific .lib file, which I'm guessing is "detours.lib" (or similar) to the "Additional Dependencies" line.
Properties->Linker->Input->Additional Dependencies.
I'm trying to run a program with GLFW in C++. I'm using visual studios 2019 on a windows 10 computer. I put the .h's and the .lib's in the proper folders and linked to them in the project settings. I'm running a minimal GLFW program I got off the internet. When I run it I get the following error:
1>------ Build started: Project: Riemannian, Configuration: Debug Win32 ------

I tried adding glfw3.dll to system32, but that didn't change anything. (side note, GLFW came with a file glfw3dll.lib. Is that just a .lib file that serves the same purpose as glfw3.dll?) Next I tried linking to opengl32.lib in my project settings. This got rid of the first error, the one with the __imp__ prefix. After that there were only 7 unresolved external symbols. My project type is "Application (.exe)" if that's relevant. I'm out of ideas and tired of googling, does anyone know what to do?
On a broader note, I have wasted so many hours trying to get libraries to work in Python, Java, and C++. I am incredibly frustrated and I wish someone could just explain to me how libraries work once and for all so that next time I have a problem I won't be completely lost.
If all this setup is too complicated, you can also just take the Glitter project as a base. It takes care of all the boilerplate and just lets you get on with writing OpenGL. As a bonus, it is based on the cross-platform CMake build tool so your project should be easy to port to other operating systems.
I am having a hard time linking cURL to my project on vs12 ...
I opted for the .msi solution that I picked here:
http://www.confusedbycode.com/curl/
and tried to link that to my project...
However I am still getting some errors after doing what I thought was right:
1>main.obj : error LNK2019: unresolved external symbol _curl_easy_init referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _curl_easy_setopt referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _curl_easy_perform referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _curl_easy_cleanup referenced in function _main
My configuration in my project vs12 is the following:
I included the include folder and the the lib folder in the vc++ directories
I added CURL_STATICLIB to the Preprocessor definition in C/C++ section as well as adding the proper include folder
I added the lib folder to the Linker sectio as well as libcurl.lib
Eventually I just included "curl.h" to the relevant .cpp file...
Is there something that I am missing?
Thank you a lot
I have problem compiling my MPI Console app I add the include & lib file but I have this errors

You need to link with your MPI import library. If you are using Microsoft MPI, it is called msmpi.lib. You can do this in two ways:
Somewhere in one of yours cpp files write the following: #pragma comment (lib, "msmpi.lib")
Open your project properties, go to Linker -> Input -> Additional Dependencies and add msmpi.lib to that list.

What's going on? I'm using Win64 OpenSSL v1.0.1e. Do I need older libraries?
from the full log it looks like one first problem is that the compiler can't find the python c header files. Then the linker can't find the python library. Perhaps the options to cl.exe are not good (shouldn't it be /ID:\... instead of -ID:\...?) or you don't have the python header files installed.
