Unable to compile OpenCV with OpenVino inference, cpuid.txt cannot be read

Question

I am trying to compile OpenCV with OpenVino inference as explained here:

https://github.com/opencv/opencv/wiki/Intel's-Deep-Learning-Inference-Engine-backend

but when I try to generate the MSVC (2017) project on windows, I am getting this error:

CMake Error at C:/local/Intel/computer_vision_sdk_2018.5.445/deployment_tools/inference_engine/src/extension/cmake/CPUID.cmake:324 (file):
  file STRINGS file "C:/local/opencv-build/cpuid.txt" cannot be read.
Call Stack (most recent call first):
  C:/local/Intel/computer_vision_sdk_2018.5.445/deployment_tools/inference_engine/src/extension/cmake/feature_defs.cmake:17 (include)
  C:/local/Intel/computer_vision_sdk_2018.5.445/deployment_tools/inference_engine/src/extension/CMakeLists.txt:9 (include)

Tools used:

OpenCV 4.0.0 source code
OpenVino 5.0.1
Visual Studio 2017
CMake-Gui 3.13

Why aren't you following the [official installation guide](https://software.intel.com/en-us/articles/OpenVINO-Install-Windows)? I think OpenVino setup comes with a predefined version of OpenCV. — zindarod, Feb 09 '19 at 14:33
@zindarod The official version is a dll version for VS and I want to build OpenCV with Inference engine and in static form. I want to build an application that I can ship as one *.exe file in windows. — mans, Feb 09 '19 at 16:28
Try this workaround: https://github.com/opencv/open_model_zoo/issues/20#issuecomment-447283964. Or use command line CMake. — Dmitry Kurtaev, Feb 10 '19 at 02:42
Well, have you checked if the file `C:/local/opencv-build/cpuid.txt` exists and is accessible ? — Mat, Feb 25 '19 at 20:11
@Mat No it doesn't exist and I don't know why it was not generated. — mans, Feb 26 '19 at 21:19

I think you have installed inappropriate versions for some tools. Please try to use CMake 3.4 or higher, which is required to build the Intel® Distribution of OpenVINO.

Please try to follow the steps from "https://software.intel.com/en-us/articles/OpenVINO-Install-Windows" for installation and verify whether you are able to compile OpenCV with OpenVino inference.

There's a forum post over on OpenVino that indicates some hacky solution to this problem. Here's the suggested solution:

In ...\Intel\computer_vision_sdk_2018.5.456\deployment_tools\inference_engine\src\extension\cmake\CPUID.cmake (assuming you followed the default OpenVino Toolkit installation, otherwise you'd need to first locate that file from where you installed it), try making the following change on line 251:

// std::ofstream fo(\"cpuid.txt\"); old line
std::ofstream fo(\"${CMAKE_BINARY_DIR}/cpuid.txt\");

^{*Make sure the variable name fo is consistent with the code following it.}

This can potentially avoid having inconsistent paths as the line 319 of that same file gets the text file like this:

set(_CPUID_INFO "${CMAKE_BINARY_DIR}/cpuid.txt")

From the stack trace, it seems like your ${CMAKE_BINARY_DIR} variable is set to C:/local/opencv-build, so you should expect cpuid.txt to be generated there.

I also met this error, but I changed this line of CPUID.cmake as shown in the followng:

if(HAVE_CPUID_INFO)
    set(_CPUID_INFO "/home/huihui/intel/computer_vision_sdk_2018.4.420/inference_engine/build/cpuid.txt")

Now the error is fixed.
