Back-ends: imgui_impl_dx9.cpp + imgui_impl_win32.cpp
Operating System: Windows 10
Compiler: Visual Studio 2019
My Issue/Question:
I keep getting constant linker errors when trying to compile my program and I cannot figure out what is causing them
I have the files required and they're included in the .sln properties and in my main.cpp

I use the GLFW example from https://www.glfw.org/documentation.html
I get these errors

I included the glfw3.lib and the headers too
I use the x64 windows precompiled binaries version 3.3.2 (latest version as of right now)
if I comment out glClear(GL_COLOR_BUFFER_BIT); function in the example code the error goes away and I'm able to compile normally and by removing the GL_COLOR_BUFFER_BIT parameter in the function i get a 'glClear': function does not take 0 arguments error
also if i comment out the function and try to render simple triangle i get a error too

I know that similar question has been asked before but I didn't find anyone with this weird behaviour
I'm trying to build poco library (c++) with openssl on windows 10 (VS 2012). With the following cmd file:

I installed openssl from "Shining Light" (win64). I also tried to use openssl which is built from source (https://github.com/pocoproject/openssl). But I get the same errors.
Can someone help me ?!
Thank you!

OK, If I delete all object files: folder obj64, including obj64 in testsuite, then every thing is ok.
I have a problem while compiling CGAL
I followed the steps here :
http://www.cse.msu.edu/~ytong/CGAL_installation.ppt
but when I reach at building CGAL .sln step
it show the following errors:

We are currently at CGAL 4.12 so please upgrade and follow official installation instructions.
I am trying to use the libnoise library, which is a c++ library for perlin noise generation, in Visual Studio 2013. Tutorial 3 links to an addon utility called noiseutils, which consists of a .cpp and a .h, which I place here:
I have the project settings pointed towards the include folder (whose contents are in the image below), and my code looks like this.
#include "stdafx.h"
#include <noise/noise.h>
#include "noiseutils.h"
int _tmain(int argc, _TCHAR* argv[])
{
noise::module::Perlin myModule;
utils::NoiseMap heightMap;
utils::NoiseMapBuilderPlane heightMapBuilder;
heightMapBuilder.SetSourceModule(myModule);
heightMapBuilder.SetDestNoiseMap(heightMap);
heightMapBuilder.SetDestSize(256, 256);
heightMapBuilder.SetBounds(2.0, 6.0, 1.0, 5.0);
heightMapBuilder.Build();
utils::RendererImage renderer;
utils::Image image;
renderer.SetSourceNoiseMap(heightMap);
renderer.SetDestImage(image);
renderer.Render();
utils::WriterBMP writer;
writer.SetSourceImage(image);
writer.SetDestFilename("tutorial.bmp");
writer.WriteDestFile();
return 0;
}
All of that code is given in the third tutorial provided on their website. Visual Studio has no complaints that it cannot find any of the classes or functions specified in all of this code. However, when I try to build the project...

In short, Visual Studio can't find any of the stuff in "noiseutils" while it's actually building. What am I doing wrong here?
UPDATE:
After copying noiseutils.cpp to my source folder as suggested by Praetorian, I get this set of warnings, and a single error:
1>------ Build started: Project: libnoisetest, Configuration: Debug Win32 ------

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I looked up this problem and discovered that I can simply disable using precompiled headers for noiseutils.cpp since it doesn't need access to stdafx. With that, problem solved.
Out of curiosity though, what is stdafx and what role does it play in a Visual Studio project? Would I need to disable precompiled headers for any source code that I add to my project so that it ignores stdafx?
Right click -> Proprieties -> C++ -> Additional Include Directories and add your headers location
Right click -> Add -> Existing Item -> Add your files
If you want
Right click -> Add -> New Filter and you put the files there
I have a solution with 2 projects in it:
The first one is called Engine and it has 3 classes: Backbuffer and Vector2 and CTimer. It is of type Console Application DLL, links winmm.lib, has all members in namespace "Engine" and if I build it (only this project) it compiles.
The other one, Game, links dependency for project Engine, is of type Win32 project, has additional include directories $(SolutionDir)\Engine\, has "Link Library Dependencies" set to true. And it does not compiles.
Both projects are compiled with "/MD" flag.
I don't know for sure if the problem is caused by VS12. Tried lots of solutions to similar errors but with no results for me.
The problem seems to be it doesn't compile the .CPP files. Thought if I compile only the "Engine" project, it compiles perfectly.
