I've been trying to build using static qt for a while but i can't get rid of these errors .

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

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 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...

Any Ideas? I'm really stuck on that one.
Thanks, Guy
Well, I found eventually a oci.lib that I can link against ("Instant Client Package")
http://www.oracle.com/technetwork/topics/winsoft-085727.html
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?
I modified an existing class in my visual C++ application to make it a generic class. This class is used by two other modules. When I compile these modules separately everything works. However, when I do a Build All, I get these linker errors:

I am using Visual Studio 2008. Does anyone know how to fix this? Prior to the modifications, everything built and linked without any problems. Thanks.
Implement your template functions in the header file.
The compiler needs to see the entire class template when it creates an actual class from the template. See e.g. Why should the implementation and the declaration of a template class be in the same header file?
This can be because the linker can't find the method bodies of your concrete class.
One workaround is to include the actual .cpp file instead of the .h file when you use declare the concrete instances of your templated classes.
