[Build] Error building opencv on Windows-Arm #24006
Description
Expected behaviour
I'm building opencv-python-headless-4.8.0.74 on Windows ARM. The aim is to generate a .whl file after running
python setup.py bdist_wheel
Actual behaviour
The build fails with an error
opencv-python-headless-4.8.0.74\opencv\modules\dnn\src\layers\cpu_kernels\conv_block.simd.hpp(461,9): error C2678: binary '+=': n

Steps to reproduce
I've installed:
1. MSVC v143 - VS 2022 C++ ARM64/ARM64EC build tools (latest)
2. MSVC v143 - VS 2022 C++ ARM64/ARM64EC Spectre-mitigated libs (Latest)
3. Windows 11 SDK (10.0.22621.0)
4. C++ ATL for latest v143 build tools with SPectre Mitigations (ARM64/ARM64EC)
5. C++ ATL for latest v143 build tools (ARM64/ARM64EC)
Command ran:
python setup.py bdist_wheel
Issue submission checklist
- This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
- 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)
- 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")
- I'm using the latest version of
opencv-python
