Installation error of OpenCV.jl with julia 1.10.2.

There is an installation error of OpenCV.jl with julia 1.10.2.
I got error message as follows.

What's wrong with OpenCV.jl ?

Hey, Images.jl is the standard package for image processing in Julia and OpenCV.jl is barely standing in older versions if even then.

Guys are not maintaining julia packages. This issue is not only with this package, but many other. Don´t know whats happening with julia language. Its losing traction.

Hi

I am sorry, but this comment contradicts the statement that OpenCV is now part of JuliaImages.
But, even if that were not the case, we still have the problem of loading time for large .tif images with the vanilla JuliaImages library, even when using ImageMagik.

This seems a problem related to CxxWrap and its artifact. It'd be better stating that fact somewhere (and nag the CxxWrap maintainers).

All the best

PS No. I am a "luser", not a developer!

Too much testosterone (and masochism) flowing towards crustaceans :)

Looks like the simple fix is to bump the Cxx compat to include 0.16 (or anything higher than 0.15) rather than the 0.13 max that is currently there. Can someone with permissions do that? (see this thread JuliaInterop/CxxWrap.jl#424)

Is there an update on this problem?

[andrew-saydjari]

I think the solution I suggested could be an easy fix, though I don't have the permissions and/or time to fix. I ended up taking @ashwani-rathee's advice, which worked for my case.

I had installed a slightly old package, tried to use an image with it, and it return error messages asking me to add OpenCV.jl (and some other packages). However, ignoring those error message requests and just installing and using Images.jl (and some of the other modern images ecosystem like ImageIO.jl) fixed all of my problems. So it seems like maybe part of the problem is that the error messages are leading people to older packages rather that the newer ecosystem? In any case, you should give that a try, unless OpenCV.jl is an explicit dependency of a package you are trying to use.

@andrew-saydjari Thanks. But OpenCV.jl is The package I'm trying to use.
