Static linking OpenCV CUDA application errors on external symbol

Question

Hi I am trying to compile a OpenCV (2.6.4) CUDA program on my Win7 Visual Studio, using static link in order to allow the program to run on another computer without CUDA/OpenCV installed. I think i got pretty close but I get stuck in these errors:

Here's what I did so far. Compiled OpenCV with:

WITH_CUDA = ON, BUILD_SHARED_LIBS = OFF

I ran opencv_test_gpu and confirmed my OpenCV was built with CUDA support. I also ensure static libs are built instead of dynamic libs, judging from the *.lib file size and simple compilation test. On the VS 2012 side:

Include Directory = C:\opencv_built\install\include, Runtime Library = /MT, Library directory = C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.5\lib\Win32;C:\opencv_built\install\share\OpenCV\3rdparty\lib;C:\opencv_built\install\lib; Additional Dependencies: cudart_static.lib;opencv_calib3d246.lib;opencv_contrib246.lib;opencv_core246.lib;opencv_features2d246.lib;opencv_flann246.lib;libtiff.lib;libpng.lib;libjpeg.lib;libjasper.lib;IlmImf.lib;zlib.lib;opencv_highgui246.lib;opencv_imgproc246.lib;opencv_legacy246.lib;opencv_ml246.lib;opencv_nonfree246.lib;opencv_objdetect246.lib;opencv_photo246.lib;opencv_stitching246.lib;opencv_ts246.lib;opencv_video246.lib;opencv_videostab246.lib;Vfw32.Lib;comctl32.lib;%(AdditionalDependencies).

Can anyone please share some insight where did it went wrong?

Answer 1

I don't believe it's possible (currently, with CUDA 5.5) to build a fully statically-linked application using the npp library. That is because a portion of the library is delivered via a dll component. Read section 15.4 here

In fact, this was not possible at all with CUDA until recently (CUDA 5.5) when a fully statically linkable CUDA runtime library was delivered. So ordinary CUDA applications can be created which don't require additional CUDA dll's to run. However, AFAIK, the libraries (e.g. CUBLAS, CUFFT, CUSPARSE, NPP) all have dll components, and don't offer a fully static version of the library to link against.

EDIT: As newer CUDA versions have been released, some CUDA libraries have incorporated static library/link options. As of CUDA 9.1, the basic CUDA runtime library (libcudart) has a static option (libcudart_static, which is now the default option for nvcc compilation), as do CUFFT (libcufft_static), CUBLAS (libcublas_static), CUSPARSE, CUSOLVER, and NVGRAPH. As of CUDA 9.0/9.1, the NPP libraries have been split into a variety of sub-libraries, but these are all available in static versions as well.
