c++ - OpenCV Unresolved External Symbols - Other Libraries Needed?

Question

I'm trying to use OpenCV 2.3.1 for a video capture and processing app. I downloaded the precompiled libraries from here and went to compile a test application using the static libraries found in the buildx86vc10staticlib of the download folder. Upon trying to compile, Visual Studio greets me with the linker errors shown below. Having worked with libpng, gzip, and a few others in the past, I recognize the functions from those libraries in the linker errors.

Does using the precompiled libraries of OpenCV also require me to link in libpng, libjpeg, gzip, and numerous others, or am I missing something?

Answer 1

I have a static build of OpenCV with most of the bells and whistles. VC10 OpenCV2.4.9(OCL woo) To fix a very similar problem I just linked to all of the following:

libpng.lib
libtiff.lib
zlib.lib
IlmImf.lib
libjasper.lib
libjpeg.lib

They were inside C:Libopencv249opencvld323rdpartylibRelease

-Not sure which one did it but what the heck. Thanks Loozie!
