When I am trying to build one of my C++ solution for x64 architecture. I am getting alot of these errors:
Error 34 error LNK2001: unresolved external symbol _forceCRTManifestCUR
Project was working fine before but I had to reinstall windows and so
VS since than it is having this problem.
It builds all fine when i build it for x32
My Operating System is Windows XP - X32 (Visual Studio - 2008) can this be the reason? I
hope it is possible to build a solution for x64 architecture while
on a x32 system?
Please guide me how can i resolve this issue.
Thankyou.

I am a Java developer whose project needs one bit of C code (DLL) that I recompile every few years when I upgrade my machine. My new machine is AMD-64bit (Windows8) so the old 32-bit DLL will not run.
I installed MS Visual Studio 12. I copied the old project to the new machine. VS migrated it. I selected build and prayed that it would work. Of course, it did not.
I get these two errors:
1>IcmpSocketN.obj : error LNK2001: unresolved external symbol __imp__printf
1>IcmpSocketN.obj : error LNK2001: unresolved external symbol __imp___ftime64_s
1>C:\temp\new_March09\ATM\Release\AtiICMP.dll : fatal error LNK1120: 2 unresolved externals
These are two standard functions so I am assuming that VS installed them somewhere.
When I did the install I selected the C++ foundation libraries. When I look at the project properties I see that the only platform option is Win32. This is a 64-bit machine. I do not know if that matters or not.
The VS install on my old machine has a VC subdirectory with a bunch of libraries in it. The new install has no such directory.
Is there some .lib or .dll that I have to download independently of the VS install? Some environment variable change?
thanks
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'm trying to use the SOIL library with freeglut and glew. I'm using Visual Studio 2012 on a Windows 8, 64bit laptop. I'm getting these errors:
1>libSOIL.a(stb_image_aug.o) : error LNK2019: unresolved external symbol __alloca referenced in function _stbi_zlib_decode_noheader_buffer
1>libSOIL.a(image_helper.o) : error LNK2019: unresolved external symbol _sqrtf referenced in function _RGBE_to_RGBdivA2
1>C:\Users\UserName\documents\visual studio 2012\Projects\VectorTest\Debug\testSOIL.exe : fatal error LNK1120: 2 unresolved externals
I found a lot of other SO questions about linking to the SOIL library, but none worked for me.
Some suggested linking in other libraries (but those seemed to be gcc specific - it was libgcc.a), others suggested building the SOIL library again.
The source code contains projects for vc6 through vc9. I built the vc9 project and tried using it - it didn't work. When I tried to build my program, it said 'The application was unable to start correctly (0xc000007b)'. I tried making a new static library project with the source code and building that, but I got the same 0xc000007b error.
It seems that this 0xc000007b error is characteristic of using a 32bit library on a 64bit computer or vice versa. However, the SOIL library doesn't come in a 64bit/32bit mode.
I've tried compiling for x64 instead of x86 but that didn't seem to work either.
What do I need to do in order to get this working?
I have a C++ program that compiled and ran fine on Linux that I am now trying to compile on a Windows machine in Visual Studio. The main problem I'm facing is the following error message:
error LNK2019: unresolved external symbol _gzread referenced in function
I have downloaded the zlib library and attempted to link it to my project, but apparently unsuccessfully. I'd appreciate clear instructions on how to link this to my project. The less you assume in your instructions, the better, as I'm relatively new to Visual Studio.
Found the solution. Even though I'm working on a 64-bit machine, VS was compiling in 32-bit mode. I just used the 32-bit version of zlibwapi instead of the 64-bit version and it worked.
