"""
|
||||
The script builds OpenCV.framework for iOS.
|
||||
The built framework is universal, it can be used to build app and run it on either iOS simulator or real device.
|
||||
|
||||
Usage:
|
||||
./build_framework.py <outputdir>
|
||||
|
||||
By cmake conventions (and especially if you work with OpenCV repository),
|
||||
the output dir should not be a subdirectory of OpenCV source tree.
|
||||
|
||||
Script will create <outputdir>, if it's missing, and a few its subdirectories:
|
||||
|
||||
<outputdir>
|
||||
build/
|
||||
iPhoneOS-*/
|
||||
[cmake-generated build tree for an iOS device target]
|
||||
iPhoneSimulator/
|
||||
[cmake-generated build tree for iOS simulator]
|
||||
opencv2.framework/
|
||||
[the framework content]
|
||||
|
||||
The script should handle minor OpenCV updates efficiently
|
||||
- it does not recompile the library from scratch each time.
|
||||
However, opencv2.framework directory is erased and recreated on each run.
|
||||
The script builds OpenCV.framework for OSX.
