Build opencv-rust fail in windows

[curly-wei]

Hi:
I sure Vcpkg and opencv4 for Vcpkg has been installed.
(I using vcpkg_cli test)

$ vcpkg_cli probe opencv4
Found library opencv4
Include paths:
  C:\SDKs\vcpkg\installed\x64-windows\include
Library paths:
  C:\SDKs\vcpkg\installed\x64-windows\lib
Runtime Library paths:
  C:\SDKs\vcpkg\installed\x64-windows\bin
Cargo metadata:
...
...
...

Source code and building refer to:

but still has error message, looks like I without installed Vcpkg-opencv.

=== Setting up OpenCV library from vcpkg
Error: "Package opencv4 is not found, caused by: Could not find library in Vcpkg tree opencv4"

warning: build failed, waiting for other jobs to finish...
error: build failed

How do I solve it

[twistedfall]

Well, the error is coming from the vcpkg crate so I'd first try setting up VCPKG_ROOT and possibly VCPKGRS_DYNAMIC environment variable (see https://docs.rs/vcpkg/0.2.8/vcpkg/). You might also want to take a look on CI files for some insight: https://github.com/twistedfall/opencv-rust/blob/master/ci/install-windows-vcpkg.sh#L1 and https://github.com/twistedfall/opencv-rust/blob/master/ci/script.sh#L13

[curly-wei]

Hi @twistedfall :
I've set those environment variables.

$ echo $VCPKG_ROOT
C:\SDKs\vcpkg
$ echo $VCPKGRS_DYNAMIC
1

But I still get the same error message.

[twistedfall]

And with those environment variables set up vcpkg_cli probe opencv4 from the project directory (where Cargo.toml is found) works correctly? That's really weird. Can you please do another couple of things for me:

1. Just to be extra sure can you please show me the output of export | grep VCPKG?
2. Try setting up OPENCV_LINK_LIBS, OPENCV_LINK_PATHS and OPENCV_INCLUDE_PATHS (see https://github.com/twistedfall/opencv-rust/blob/master/README.md#environment-variables) to point to the files installed by vcpkg and then building the project again. This will avoid using vcpkg to find the package.
3. Alternatively can you try creating a new empty project that depends on vcpkg crate and call let opencv = vcpkg::find_package("opencv4").expect("Can't find opencv4"); dbg!(&opencv); in it and run that project. Does it manage to find the package?

[curly-wei]

Hi @twistedfall :
I run cargo build in top location of my workspace:

$ ls
Cargo.lock  Cargo.toml  src/  target/

Your 3 recommend I did:
1.

$ export | grep VCPKG
declare -x VCPKGRS_DYNAMIC="1"
declare -x VCPKG_ROOT="C:\\SDKs\\vcpkg"

but still can't build

It throw lots of new error message
(fill out my terminal)

3. I got following error message, it should be useful:

thread 'main' panicked at 'Can't find opencv4: NotMSVC', src\libcore\result.rs:1188:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.
error: process didn't exit successfully: `target\debug\find_opencv.exe` (exit code: 101)

[twistedfall]

Well, for that error the following can be found:

    /// On Windows, only MSVC ABI is supported
    NotMSVC,

    Error::NotMSVC => "vcpkg-rs only can only find libraries for MSVC ABI 64 bit builds",

    "the vcpkg-rs Vcpkg build helper can only find libraries built for the MSVC ABI."

if !target.contains("-pc-windows-msvc") {
        Err(Error::NotMSVC)
    }

so looks like abi/toolchain mismatch between what crate expects and what opencv in vcpkg was compiled with. Kind of weird considering that vcpkg_cli works correctly. Which toolchain your Windows rust is built with? Did you install it using rustup?

[curly-wei]

Hi @twistedfall
There are so weird.
My opencv4 is installed by vcpkg,
I don't download opencv soruce code to build or download opencv builded binaries files.
The opencv4 vcpkg provided(I selected x64 version installing), it should be msvc version...
I also try to remove all of vcpkg, reinstall vcpkg and opencv4 again,
but still got the same error.

[twistedfall]

Can you try the option 2 again?

Try setting up OPENCV_LINK_LIBS, OPENCV_LINK_PATHS and OPENCV_INCLUDE_PATHS (see https://github.com/twistedfall/opencv-rust/blob/master/README.md#environment-variables) to point to the files installed by vcpkg and then building the project again. This will avoid using vcpkg to find the package.

Build with -vv and please share the full build log. It should work in any case or should provide more insight into why it's failing.

[curly-wei]

Hi : @twistedfall
I've tried.
First, I setting following env.

OPENCV_HEADER_DIR=C:\SDKs\vcpkg\installed\x64-windows\include\opencv2
OPENCV_INCLUDE_PATHS=C:\SDKs\vcpkg\installed\x64-windows\include\opencv2\core

OPENCV_LINK_PATHS=C:\SDKs\vcpkg\installed\x64-windows\lib
OPENCV_PACKAGE_NAME=opencv4
OPENCV_PYTHON3_BIN=C:\Python37

I got error messages below:

I've fixed.
But error messages still same to above:

Oops, missed another one: OPENCV_HEADER_DIR needs to also be C:\SDKs\vcpkg\installed\x64-windows\include

The problem seems to be in OPENCV_PYTHON3_BIN, it must point to the actual binary, not the directory, so something like C:\Python37\python.exe.

Hi: @twistedfall :
I've fixed, it seems start to compile, but still has error and....
