I am trying to build a C++ Visual Studio 2005 solution in Visual Studio 2010.
I fixed some of upgrade issues so far when building the solution in the Visual Studio 2010.
However the last thing I do not know how to fix is the below link error message:
LNK2019 unresolved external symbol _hypot referenced in function _gsl_matrix_complex_long_double_div_elements in libgsl_d.lib.
Does anyone know of this issue?
TIA
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'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?
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?
