Hi,

I'm unable to install OpenCV-Dynamic with cocoapods. After playing around a while now I'm still not able to identify what I'm missing.

MacBook-Pro:project user$ xcodebuild -version
Xcode 8.2.1
Build version 8C1002

MacBook-Pro:hazmat user$ gem list --local cocoapods

Hm, look slike there is an incorrect value returned by getXCodeMajor function. Can you try xcode-select --install and report what is returned by xcode-select --version ?

The Podspec file should call /usr/bin/python instead of just python. The error above looks like it is calling python 3 instead of python 2. If Anaconda, or some other python, is installed, the python found in the path is not necessarily the right one.

Additionally, a check if cmake is installed would be nice. I got tripped up on that for a bit.

Legoless commented 6 years ago

Both very good points, will add it once I find some time.

From 4.0.0-alpha1, /usr/bin/python is called instead of python.
