I'm trying to link to a static build of Qwt. to create the static build, I modified qwtconfig.pri to contain
#QWT_CONFIG += QwtDll
and I removed all the #define QWT_DLL references in the code.
However, when I link to the library, I get a bunch of undefined references complaining about QSvgRenderer:

Is there something else in the project configuration I need to do so it can link properly to QSvgRenderer?
Guess your version of Qt is without SVG support - or you forget to add it to your project dependency. If you are not interested in SVG stuff at all you could also disable it in qwtconfig.pri as well:
See: "QWT_CONFIG += QwtSvg"

I've been like a pair of days trying to get a C++ app, but i'm stuck in the library / dll process, I have problems with those two.
I downloaded the c++ release for protobuf 3.0.0, made the .lib and the .dll ( to test the two of them ), I used this in order to get the .sln
cmake -Dprotobuf_BUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX="../install" ../cmake
it gave me a solution which I opened with vs2015 and compiled for debug, then compiled me the files, then I generated the includes with the .bat provided.
So, when I go to VS2015 and try to compile with the .lib linked, it gives me this error

I am sure that I'm running the app in the lib building as debug and the game as debug too.
Also, I tried the .dll ( deleting the library and the references ), writing in the top of the main.cpp file "#define PROTOBUF_USE_DLLS" and I get a lot of linker errors like this

I'm a bit lost and stuck, so if anyone can help me to redirect where I have to search for, I'll be grateful.
Thank you for your time
As I can't comment, will post this as an answer.
If I understood the structure of your projects correctly, this thing:
`1>libprotobufd.lib(dynamic_message.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj`
tells you that the Runtime library setting for the library you're trying to link and your project does not match.
Check Project Properties -> C/C++ -> Code generation -> Runtime Library and make sure this setting is the same for both projects.
P.S. also having a problem linking with static library containing proto-files in vs2015 update 3 but seems that your case is different..
Maybe you should add the PROTOBUF_USE_DLLS define in the Visual Studio project properties under C/C++ -> Preprocessor -> Preprocessor definitions? I'm guessing you might need that define when compiling protobuf the protobuf output cpp files too.
Like any other BulletPhysics app, my VS2010 project refers to three other projects : BulletDynamics , Bullet3Collision and LinearMath.
It is a simple BulletPhysics test project, I tried multiple options but none of them seem to work :
Individual projects (BulletDynamics , Bullet3Collision and LinearMath) -> properties -> Librarian -> Link Library dependencies.
BulletTestProject -> Properties -> Common Properties -> Framework and References -> Added above three projects with Link Library dependencies true.
BulletTestProject -> Properties -> Configuration Properties -> Linker -> Add additional Libraries & -> Input -> Add aditional dependencies.
Tried above three but none seem to work.
Any help is appreciated to fix the linker error.

========== Rebuild All: 3 succeeded, 1 failed, 0 skipped ==========
I'm working on a C++ assignment (C++98 & VS2010) using OSG and a pre-built template project to work on. I'm trying to implement mouse picking using the osgUtil/LineSegementIntersector and osgUtil/IntersectionVisitor classes. Unfortunately when I run this code I get a bunch of LNK2001 and LNK2019 errors. The two classes are included at the top of the file, the folder with the osg libraries is included in the linker and the osgUtild.lib file is present in the directory.
The Code:
osgViewer::Viewer *pViewer=dynamic_cast<osgViewer::Viewer*>(aa.asView());
osgUtil::LineSegmentIntersector* picker;
picker = new osgUtil::LineSegmentIntersector(osgUtil::Intersector::PROJECTION, ea.getXnormalized(), ea.getYnormalized());
osgUtil::IntersectionVisitor iv(picker);
pViewer->getCamera()->accept(iv);
if(picker->containsIntersections())
{
osgUtil::LineSegmentIntersector::Intersections intersections = picker->getIntersections();
for(osgUtil::LineSegmentIntersector::Intersections::iterator it = intersections.begin(); it != intersections.end(); it++)
{
for(NodePath::const_reverse_iterator rit = it->nodePath.rbegin(); rit != it->nodePath.rend(); rit++)
{
}
}
}

I can't see anything wrong with my code or my setup, my only thoughts at the moment based on everything I've read is that there's something not being included (a dll somewhere or similar) by the osgUtil library but I can't see how I would be able to resolve that.
Any and all advice would be appreciated - though I definitely require sleep soon so I may not respond immediately.
Dlls are not included at compile time. Specifying the folder only is not sufficient. you need to specify that you are going to use OsgUtild.lib explicitly to linker.
I was given an assignment to compile a 3d Max plugin in 64 bit.
Project compiles properly under 32 bits, but when I follow the instructions from here:

to setup compile platform to x64. The project compiles, but when Generating Code I get linker errors:

What am I doing wrong?
As a follow-up for anybody having the same problem: You need to select x64 variant of the libraries at the Linker->General->AdditionalLibraryDirectories. Once you install 3Ds MAX SDK with the default options you should have them located at: C:\Program Files (x86)\Autodesk\maxsdk\x64\lib;
I am trying to build an open source C++ project in Visual Studio 2008. I load the solution file and everything compiles, but I'm getting a bunch of linking errors due to certain methods not being found. After using DUMPBIN.EXE to examine the .lib file in question, I can see what the problem is: the methods in the .lib all have __cdecl in their signatures, while the linker is looking for the equivalent methods with __thiscall instead.
How can I get VS 2008 to use __cdecl instead?
NOTE: The project is a fork of CCV, a multi-touch tracking program based on OpenCV. The purpose of this fork is to provide support for a camera called the Flea3 via the FlyCapture2 libraries provided by the camera's maker. Here are the linker errors:

By default Visual Studio will use __thiscall for member functions. Since it compiles correctly, it seems like the headers in your library do not explicitly declare the calling convention.
It sounds like you need to use C linkage against the library. Try wrapping the library headers with
extern "C" { }
The problem was that I was linking against the 64-bit version of the external FlyCapture2 library. Switching to the 32-bit version solved the problem.
