how to update ncnn native? ncnn_20210507 has a lots improvement. about ncnndotnet HOT 4 CLOSED

@goodtogood

I tried the following steps.

cd src\ncnn
git fetch -ap
git checkout ae14ca91ac9eedf590ca12d3dff4810d98027b65
cd ..\..\nuget
git submodule update --init --recursive
pwsh BuildWindows.ps1

It should generate build_win_desktop_vulkan_x64\Release\NcnnDotNetNative.dll and build_win_desktop_cpu_x64\Release\NcnnDotNetNative.dll.
But I have not yet checked whether binary works or not.

I tried two times as you said above
but same error occurred when building NcnnDotNet.Native
opencv@x64 was built successfully
I was confused about the error message
thx

• We use VS 2017 rather than 2019
  • https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-windows-x64-using-visual-studio-community-2017
• Did you install OpenCV Windows pack to system?
• I have never faced to your error message but it could do something to wrong.

@takuya-takeuchi

• I made a little modification to use VS 2019. actually NCNN has been built successfully when using command pwsh BuildWindows.ps1
• Yes, there's another OpenCV pack within system path, maybe it's the problem.

I'll try again, thank you so much.
