Fails to link any program using opencv due to multiple missing dependencies

[unjello]

I am unable to produce a binary using opencv-rust, due to linkage errors as below.

1. Operating system

Windows 10 19041.421

2. The way you installed OpenCV: package, official binary distribution, manual compilation, etc.

vpkg install opencv[contrib,cuda,dnn,ffmpeg,jpeg,nonfree,opengl,png,tiff,webp]:x64-windows-static-md

3. OpenCV version

opencv4:x64-windows-static-md 4.3.0 computer vision library

Cuda is also installed as a dependency, automatically by vcpkg:

cuda:x64-windows-static-md                         10.1#2           A parallel computing platform and programming model
cudnn:x64-windows-static-md                        7.6#2            NVIDIA's cuDNN deep neural network acceleration ...

4. Attach the full output of the following command from your project directory:
   There's multiple dependencies missing for cuda, native windows (tls, bcrypt, win32 windows), and in protobuf (dnn component of opencv depends on it) too.

Hi, I'd like to see the full build log as you get it when you run cargo build -vv

Hi, thanks for getting back. I've updated the gist to show the full log.

[twistedfall]

I think that the last lines of the log are cut out, I can't see the linking error anymore

[unjello]

Yes, the gist does truncate the output. Here's the link to full raw (you can find it at the top of initial screen too):

Are you using a nightly compiler? If so which particular version? Can you try with a stable Rust? 1.45.2 that is

[unjello]

FWIW, I just dig through docs enough to find $env:VCPKGRS_DYNAMIC="True" and when it picks x64-windows triplet instead of x64-windows-static-md it works. All compiles successfuly.

And I'm using:

PS> rustc --version
rustc 1.47.0-nightly (f9d422ea7 2020-08-04)

[twistedfall]

Ah, I'm going to update the troubleshooting guide with that info, thanks!

[unjello]

I am not sure if it's not closed too early. Static linking would me more idiomatic for rust. But that also may be vcpkg crate issue.

[twistedfall]

Well, for static linking the is a separate issue: #104 but so far I haven't investigated that. It would definitely be good to have such option.
