Can you check if this version works for you? https://github.com/wandenberg/opencv4nodejs/commit/91bc118a43da570638db466e51cf56dbbf615b9e It was updated to compile with OpenCV 4.5.2+

OK, I will try with this version.

[Jiyvn]

@wandenberg Really thankful for your support. I've struggle with opencv4nodejs for days and days

I am able to install with node v14.18.1 on MacOS 10.15.6, but error with node v16.13.0 (opencv-build installed with opencv 4.5.3)

Hi @Jiyvn sorry for the long delay. I could not find the exact reason for the error with Node16 + macOS, since the error trace does not start on this module code, but I found a workaround that is to specify the CXXFLAGS="--std=c++17" during installation. Something like CXXFLAGS="--std=c++17" npm install. At least it worked for me. I am looking for a way to specify this either on the code or on the package.json, if someone knows how to do it, please say it ;)

[wandenberg]

I think I got it, can you try with this branch? https://github.com/wandenberg/opencv4nodejs/tree/change_compile_flags

Use this, and worked! Thank you @wandenberg .

[Jiyvn]

@wandenberg This change on branch change_compile_flags solved this problem on my side. I did successfully install opencv4nodejs with node 16.13.0. really thankful for your help, appreciate it

[chrisspiegl]

I also used the branch by @wandenberg.

Since the last release on this repo was about 2 years ago at the time I was looking at it. Is there a chance this could get merged?

npm install @u4/opencv4nodejs

This fork contains @wandenberg change and may more and is actively maintained.

I found the support from appium https://github.com/appium/appium/releases/tag/%40appium%2Fsupport%402.55.3 will appium focus on your fork in the near future? @UrielCh

[UrielCh]

Hi, I did not get notified about that. If they want to use my fork they are welcome.

worked for me as well @wandenberg thanks
