OpenCV 2.0 with Visual Studio C++ 2008

Question

See more:

I have followed instructions how to install and prepare for use OpenCV.
But while running code that includes cv.h I'm getting linker errors

VB

CPP_DS_CapSample.obj : error LNK2028: unresolved token (0A0008E6) "void __cdecl cv::fastFree(void *)" (?fastFree@cv@@$$FYAXPAX@Z) referenced in function "public: void __thiscall cv::Mat::release(void)" (?release@Mat@cv@@$$FQAEXXZ)
1>CPP_DS_CapSample.obj : error LNK2019: unresolved external symbol "void __cdecl cv::fastFree(void *)" (?fastFree@cv@@$$FYAXPAX@Z) referenced in function "public: void __thiscall cv::Mat::release(void)" (?release@Mat@cv@@$$FQAEXXZ)

I'm stuck with it.

I did create files with CMake.
And then compiled whole project in cmakecompile folder
I did add environment variables - paths to :
C:\OpenCV2.0\ cmakecompile\ bin\Debug; C:\OpenCV2. 0\cmakecompile\ bin\Release

In Tools->Options->VC++ Directiories added:
in Executible files:
C:\OpenCV2.0\ cmakecompile\ bin\Debug
C:\OpenCV2.0\ cmakecompile\ bin\Release
in Include files:
C:\OpenCV2.0\ include\opencv
in Library files:
C:\OpenCV2.0\ cmakecompile\ lib\Debug
C:\OpenCV2.0\ cmakecompile\ lib\Release

But still no joy.

Solution 2

Hmmm

I've added those:

C#

#pragma comment (lib, "cv200.lib")
#pragma comment (lib, "cvaux200.lib")
#pragma comment (lib, "cxcore200.lib")
#pragma comment (lib, "cxts200.lib")
#pragma comment (lib, "highgui200.lib")

and IT WORKS :)

Thank you

Is there any other equivalent of this operation that works project wide?

It works tried it again and it was fine I guess I had to omit something first time I tried that.
Funny enough I was trying it before my first post here,
at least now I know more elegant way.

Thanx

Solution 3

OK :)
Yes, you could set them separated by space in the:
poject->property->linker->input->additional dependencies :)
