Issue submission checklist

[x] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
[x] I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
[x] The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
[x] I'm using the latest version of opencv-python

Could you bring more details, logs, etc?

Miniontoby commented 2 years ago

I would love to, but all the lines of logs are in 1 line without breaklines...

Also idk how to easily copy to my laptop or my new phone

The logs are the same as at this issue at the comment of "RSwarnkar"

asmorkalov commented 2 years ago

The issue is related to CMake tool, but not OpenCV. It fails to build with libarchive. At least it's what I see from logs in the related ticket. There is nothing to fix in OpenCV for now. As hack or workaround you can do the following:

Install cmake from bre-built archive / package manager / build from sources with limited options.
Hack OpenCV-Python package and exclude cmake package from dependencies. System provided cmake should be used then.

Miniontoby commented 2 years ago

Can you tell me how to 'hack' opencv-python to exclude the cmake package?

I know a lot, but cannot figure this one out yet

EDIT: I think i did it, but still it failed. Here is the logs: https://termbin.com/1gm1

I managed to install it, but it not listed in pip list

pkg list-installed:

opencv-python/x11,now 4.10.0-2 aarch64 [installed]
opencv/x11,now 4.10.0-2 aarch64 [installed,automatic]

RealYukiSan commented 3 weeks ago

nvm, the output of pkg list-installed is false-positive, and it didn't printed on apt list --installed or pkg files opencv-python

RealYukiSan commented 3 weeks ago

after some update & upgrade and reinstall the package, somehow it now properly installed. even though it will not listed on pip list command, you can still use it. maybe the reason it didn't listed on pip because package naming convention? opencv-python instead of python-opencv make it invisible from pip? because I install python-numpy with pkg and it's listed as well on pip.
