Trouble building NVIDIA VisionWorks (OpenVX) on Windows - build

Question

I am attempting to install VisionWorks on Windows as described in the link named "VisionWorks 1.0 for Windows README" on this page:
https://developer.nvidia.com/embedded/visionworks
According to the README document VisionWorks is compatible with Windows with the following configuration:
OS : Windows 8 x64
OpenCV : public OpenCV 2.4.12
CUDA : NVIDIA CUDA 7.0
I am using exactly this same configuration with the following variables as described in the README (with my specific PC's paths):
[CUDA_VERSION] : 7.0
[CUDA_INSTALL_DIR] : C:\cuda\v7
[OpenCV_INSTALL_DIR] : C:\opencv
[OpenCV_VERSION] : 2412
[VisionWorks_VERSION] : 1.0
[VisionWorks_INSTALL_DIR] : C:\cuda\VisionWorks
[SAMPLES_BUILD_DIR] : C:\cuda\VisionWorks\SAMPLES_BUILD_DIR
I follow the directions in the README as seen below (Images at end of post):
Step 1:
Copy samples from [VisionWorks_INSTALL_DIR]\share\visionworks\sources to a
directory with write access [SAMPLES_BUILD_DIR].
Step 2:
Open Visual Studio's Developer Command Prompt - VS2013 x64 Native Tools
Command Prompt.
Step 3:
Go to the [SAMPLES_BUILD_DIR]:
> cd [SAMPLES_BUILD_DIR]
Step 4:
Edit the config.nmake file to insert correct paths for all prerequisite
installation directory information.
# Dependency locations
CUDA_DIR = [CUDA_INSTALL_DIR]
OPENCV_DIR = [OpenCV_INSTALL_DIR]\build
OpenCV_VERSION = [OpenCV_VERSION]
VISIONWORKS_DIR = [VisionWorks_INSTALL_DIR]
# Debug build?
dbg = 0
Step 5:
Build samples using nmake
> nmake
But when I execute the nmake command I get the following error:
C:\cuda\VisionWorks\SAMPLES_BUILD_DIR> nmake

Answer 1

The issue is that there is a bug (more a feature lacking implementation) in the VS 2013 compiler. Function template parameters are only deduced based on types in the arguments, so a call with no arguments will not trigger deduction.
The rather ugly workaround for VisionWorks is to replace the template in Range.hpp
/*
* \ingroup group_nvxio_range
* \brief Creates a range that includes all points.
* \return The range.
*/
template <typename T>
inline Range<T> all() {
return { std::numeric_limits<T>::lowest(), std::numeric_limits<T>::max(), true, true };
}
with a template with a dummy argument, and fix the uses in OptionHandler.hpp accordingly.
/*
* \ingroup group_nvxio_range
* \brief Creates a range that includes all points.
* \return The range.
*/
template <typename T>
inline Range<T> all(T dummy) {
return { std::numeric_limits<T>::lowest(), std::numeric_limits<T>::max(), true, true };
}
so that the calls in OptionHandler.hpp looks like
static ptr real(float *result, const Range<float> &validRange = ranges::all<float>((float)1));
So this makes the code pretty fugly, and defeats somewhat the purpose of the template. This templating issue is fixed in VS 2015, but CUDA doesn´t compile in 2015, which makes more advanced use of OpenVX pointless.
