First, let me start by saying I've read EVERY post, link, answer, etc I can find that points to Linking/External Symbol errors in Visual Studio/C++. With that said, here are the 27 errors I'm getting:

1>C:\Users\ME\Downloads\synergy-master\synergy-master\lib\MinSizeRel\ns.dll : fatal error LNK1120: 26 unresolved externals
Some background: I've downloaded Synergy from their GitHub and built it without error. Getting it to build took a small amount of hacking because they don't officially support Visual Studio 2013, but not overly difficult. I also built is using the latest Qt instead of the one they provide on their site (2010) I'm also using OpenSSL from SLProWeb, 32-bit full version.
Anyway, I cleared up a minor error or two in their code and tried to compile it first from command line, and second with VS GUI. Both spit out the 27 errors shown above. As I said, I've searched high and low trying to figure out what I've done wrong, but ultimately found nothing. I copied ssleay32.lib and libeay32.lib, with their .dlls, into the /ext/openssl/out32dll folder, where Synergy looks, which didn't work, so I pointed the linker additional libraries directory to it manually and also added it to the additional includes, and added the two .libs to Input>Additional Dependencies. Still no good.
In a last ditch effort, I added this to the top:
#pragma comment(lib, "libeay32.lib")
#pragma comment(lib, "ssleay32.lib")
#pragma comment(lib, "libeay32MD.lib")
#pragma comment(lib, "libeay32MDd.lib")
#pragma comment(lib, "libeay32MT.lib")
#pragma comment(lib, "libeay32MTd.lib")
#pragma comment(lib, "ssleay32MD.lib")
#pragma comment(lib, "ssleay32MDd.lib")
#pragma comment(lib, "ssleay32MT.lib")
#pragma comment(lib, "ssleay32MTd.lib")
while also copying the rest of the libs into the out32dll folder. This proved that it know the files existed, but still refused to resolve the External Symbol issue.
To me, it looks like it isn't properly loading libeay32.lib, which contains the crypto portion of OpenSSL that the compiler complains about....

I'm writing a c++ file to build into mex, but I got the unsolved external symbol errors with asio function like "ASIOExit". I'm building in Matlab console with mex command.
I've put all headfiles and cppfiles from the AsioSDK. into one folder ad used -I to include that folder. What else do I need to include or link?
The 3 headfiles related to ASIO has already been added in include.
#include "asiosys.h"
#include "asio.h"

I am using these libraries :
ws2_32.lib
imm32.lib
winmm.lib
qtharfbuzzng.lib
qtpcre.lib
Qt5PlatformSupport.lib
qwindows.lib
opengl32.lib
Can any of you explain me what i am doing wrong ? Thank you.
I've had the exact same issue. You're missing the freetype library qtfreetype.lib.
Add the following line to your .pro file
LIBS += -lqtfreetype
You need QtCore and QtGui at a minimum for this. QString is in QtCore and QGuiApplication is in QtGui. If your Qt usage is restricted to user interface activities, that might be enough. Otherwise, for each class that's failing to link, look in Qt Assistant. The "qmake" note at the top of the page says which library contains that class.
For instance, for Qstring, it has "qmake: QT += core". For Visual Studio on Windows, the actual filenames for the "core" library are Qt5Core.dll (release) Qt5Cored.dll (debug).
Added my case, hope this will helpful.
I'm lost one CPP file in the library project
Be careful when compilation (Lib & Project) has different option MT/MD options
I'm trying to compile the zeromq sources and I have the following error:
I'm using Visual studio 2013 update 4 / windows 7 x64
First of all I compile the libsodium library satisfactorily.
Then I link the libsodium header files directory path to additional dependencies and libsodium.lib to additional library directories. I also specify the name of library in additional dependencies.
I try to compile it under win32 architecture and x64 architecture but I get the same errors.
I know that a __imp prefix is used as a bridge to the function that I want to use so if I linked the libraries appropiately why do I get this error?

Thanks in advance.
You're probably compiling libsodium in a static way.
Try to compile it dinamically and link it again.
Such errors are also able to occur when you have a wrong set calling convention at your project.
I am trying to build OSGEarth using CMAKE and Visual studio 2013
I first downloaded Open Scene Graph 3.2 and the prebuild dependencies (small package) from this page. I generated the visual studio 2013 project and build/installed Open Scene Graph without much problem
After that, I downloaded the source of osgearth 2.5 and generated the Visual Studio 2013 project, using the same dependencies as for Open Scene Graph (I don't want to use the optional dependencies for the first build) and when I try to build the osgEarth project, I got the following error at the linking step :

The only think I was able to find is that all the missing method seems to be deprecated ODBC method, like this one
For additional information, the project got a reference to odbc32.lib in its inherited values.
Okay, stupid question... the odbc's dependencies were in the inherited values... but the checkbox indicated to the build process to use these dependencies was not checked. Once it was done, everything is good... I think I need either a coffee or a very big smack on the head...
I'm having some problems with using CEF in my application which uses the MD/MDd runtime library linking.
I have downloaded the latest build of CEF3 from cefbuilds.com and followed the instructions How to link CEF against a different run-time library.
I have built the "libcef_dll_wrapper" project after changing "Runtime Library" to "/MDd" and "Platform Toolset" to "v110" and then I've linked the resulting "libcef_dll_wrapper.lib" binary to my project.
However, when I try to build my project I get the following errors:

The full log can be found here.
Any ideas as to what I might be missing?
Are you also libcef.lib in the linker input?
