Install error regarding members in FaceRecognizer.o

[kriston13]

Hi All,

running mac: 10.12.6 node: v8.4.0 npm: v5.4.0 opencv: v3.3.0

running npm install opencv goes into the build process (cause the amazon link is still dead), and it fails on attempting to compile FaceRecognizer.o with the following set of errors:

4 warnings and 8 errors generated.

It then proceeds to fail with an exit code of 2.

There are also other deprecation warnings, but this is the first set of errors...

Does anybody have any idea what's happening...? And how to fix it? Thanks!

I encountered the same error and was able to at least npm install opencv after switching back to opencv 2.4.13. To do that I did (unfortunately a bad idea if you want opencv 3.3.0 installed for other purposes)

brew remove opencv
brew install opencv@2
brew link opencv@2 --force

[VirgileD]

the api has changed: cv::face::createEigenFaceRecognizer is now cv::face::EigenFaceRecognizer::create(). the same goes for all face recognizers. and, also, I had another problem right after this one: faceRecognier->load is now faceRecognier->read.

[AbdulrahmanHajeKarim]

This is correct, it worked for me! as VirgileD suggested it should be cv::face::EigenFaceRecognizer::create()
