While porting a desktop application to windows mobile I've reached the following error:
Error LNK2019: unresolved external
symbol CompleteAuthToken referenced in
function
Reading MSDN it tell me that CompleteAuthToken is supported on Windows CE 2.10 and later and I should link against Secur32.lib, but adding that library didn't fix the unresolved symbol error. Any ideas?
Note: I'm using Visual Studio 2008 + Windows Mobile 6.0 SDK.
I think the MSDN docs are wrong. Looking in the Platform Builder source, I see that CompleteAuthToken() is in schannel.def and that it gets built into schannel.lib, not secure32.lib. See if making that change helps.
Did you include Security.h?

I'm trying to compile an empty "qt widgets application" project created with Qt Creator.
It gives me various linking errors like
MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol __imp__EncodePointer#4 referenced in function _pre_c_init
MSVCRTD.lib(atonexit.obj) : error LNK2001: unresolved external symbol __imp__EncodePointer#4
and so on.
Building qt examples gives the same error.
I have Visual Studio 2010 and Windows SDK installed, the right compiler seems to be chosen.
UPD: I have switched to miniGW compiler and it works now. Not sure if that solution is suitable for everybody.
I'm encountering a strange bug in Visual Studio 2010...
I work with the Kinect for Windows SDK v1.8 on VS 2010 Ultimate, for a speech recognizer program using the MS Kinect.
Like it's explained in the sample SpeechBasics (available on Kinect Developer Toolkit Browser), I added the specifics VC++ include and library paths into my project properties, before listing the default system include and library directories.
But When I buid the solution, I get the following errors :
CKinect_Squeletton.obj: error LNK2001: unresolved external symbol _SPDFID_WaveFormatEx
CKinect_Squeletton.obj: error LNK2001: unresolved external symbol _CLSID_SpStream
CKinect_Squeletton.obj: error LNK2001: unresolved external symbol _CLSID_SpInprocRecognizer
CKinect_Squeletton.obj: error LNK2001: unresolved external symbol _CLSID_SpObjectTokenCategory
build failed.
I had checked all my include files, all my project properties. I did a lot of research, and tested many possibilities of response, but I hadn't found response for my problem...
I have tried cleaning the solution, build with a x64 target architecture, but that doesn't always work.
Why have I this problem ?
Like suggested in the comment, I've checked the link on social MSDN
I've resolved some errors but not all in using __uuidof(SpStream) instead of CLSID_SpStream , and __uuidof(SpInprocRecognizer) instead of CLSID_SpInprocRecognizer .
But i don't found CLSID_SpObjectTokenCategory in my code, I have only
ISpObjectToken *pEngineToken = NULL;
hr = SpFindBestToken(SPCAT_RECOGNIZERS,L"Language=40C;Kinect=True",NULL,&pEngineToken);
I can't replace it with __uuidof(SpObjectTokenCategory) .
Also, I always don't know how to resolve the error
CKinect_Squeletton.obj: error LNK2001: unresolved external symbol _SPDFID_WaveFormatEx
I've added sapi.lib in Project + Properties, Linker, Input, and I also try with #pragma comment(lib, "sapi.lib")
I have resolved my problem !
I work on Windows 7 64bit, and I had installed MS Speech Platform SDK 11 x64.
But to build with a x86 target architecture , I had to install and use MS Speech Platform SDK 11 x86, and specify in my project properties the path for the x86 sapi lib !
The compiler gave me errors when I've tried to build with a x64 target architecture, because others specific libraries that I have included in the project are for a x86 architecture...
Sorry and maybe this solution will help someone one day !
I am trying to build this simple visualization example using VS2010:
http://pointclouds.org/documentation/tutorials/pcl_visualizer.php
I have linked all .lib files (both pcl and 3rdparty) however I get a bunch of unresolved external symbol errors all of which are happening on vtkRendering-gd.lib and seem to be OpenGL related like the following:
vtkRendering-gd.lib(vtkOpenGLTexture.obj) : error LNK2001: unresolved external symbol __imp_glPopAttrib
vtkRendering-gd.lib(vtkOpenGLRenderer.obj) : error LNK2001: unresolved external symbol __imp_glPopAttrib
vtkRendering-gd.lib(vtkOpenGLRepresentationPainter.obj) : error LNK2001: unresolved external symbol __imp_glPopAttrib
vtkRendering-gd.lib(vtkOpenGLLight.obj) : error LNK2001: unresolved external symbol __imp_glPopMatrix
I am on a x64 Windows 7 machine, and I have installed the x64 version of PCL using the all-in-one installer.
Thanks for your help.
in the http://www.pointclouds.org/ it says that the visualization library is ment to work in Qt. It might be using Qt GUI features .any way I suggest you check if your error is coming from it.
(although I know that you could define your own GUI with other engines like opengl)
I'm using VS10 + Win64 + pcl with no issues. But I used another way of installation.
I installed dependencies (http://www.pointclouds.org/downloads/windows.html) from column Windows MSVC 2010 (64bit)
In particular:
boost 1.50.0
Eigen 3.0.5
FLANN 1.7.1
VTK 5.8.0 with Qt support
Qt 4.8.0
QHull 2011.1 (6.2.0.1385)
OpenNI OpenNI 1.5.4 (patched)
OpenNI Sensor 5.1.0 (patched)
After installing them one after another I followed instructions on this page http://pointclouds.org/documentation/tutorials/compiling_pcl_windows.php#compiling-pcl-windows
And I had no problems, everything is working fine.
You are missing opengl32.lib
Add it to Properties->Linker->Input->Additional Dependecies
I have been having this issue for a very long time, I have not even had no luck and it is becoming very frustrating. I am really itching to create games in C++ with OpenGL/SDL. I am using Microsoft Visual Studio Ultimate 2012. My Operating System is a 64-bit Windows 7.
I had no troubles setting up OpenGL with Visual Studio, but SDL is the main problem. I follow lazy foo tutorials, I looked at YouTube videos, god damn it is irritating. The error I am getting when debugging SDL in Visual Studio is:
1>SDLMain.obj : error LNK2019: unresolved external symbol _SDL_Init
referenced in function _SDL_main 1>SDLMain.obj : error LNK2019:
unresolved external symbol _SDL_Quit referenced in function _SDL_main
1>MSVCRT.lib(crtexew.obj) : error LNK2019: unresolved external symbol
WinMain#16 referenced in function __tmainCRTStartup
I do not know what you mean by building the libraries by myself, but I did link the SDL Library. I switched from x64 to x86 and when I debugged my code again I got this message:
The application was unable to start correctly (0xc000007b). Click OK to close the application.
So your saying if I downloaded an earlier version of Visual studio, I can run SDL without a problem?
I am trying to build libxml2 library with VS 2012 compiling and linking against DDK 7 headers and libraries. With VS 2005 it builds fine but with VS 2012, I am getting a linker error. On close inspection of symbols generated -
On VS 2005,
Found __imp___vsnprintf
Referenced in error.obj
Referenced in xmlreader.obj
Referenced in xmlwriter.obj
Referenced in xmlstring.obj
Loaded msvcrt.lib(msvcrt.dll)
On VS 2012,
error.obj : error LNK2019: unresolved external symbol __imp__vsnprintf
referencedin function ___xmlRaiseError
xmlreader.obj : error LNK2001: unresolved external symbol __imp__vsnprintf
xmlwriter.obj : error LNK2001: unresolved external symbol __imp__vsnprintf
xmlstring.obj : error LNK2001: unresolved external symbol __imp__vsnprintf
__imp__vsnprintf, __imp___vsnprintf on VS 2012 and VS 2005 respectively for the same function ( Notice the extra _ mark before vsnprintf in VS 2005). I looked at the compiler and linker options for the VS 2005 and VS 2012 in the build log. Both are the same. With the showIncludes option passed to the compiler, I see the exactly same set of headers used for the source files on both VS 2005 and VS 2012.
Why is yet the symbol generation in VS 2012 being different ? How to resolve the issue with out compiling and linking against default headers and libs ?
Thanks.
Do not use DDK for building user-mode components. DDK stands for Driver Development Kit. Using it for user mode is undefined behavior. Use SDK instead.
