""" |
|
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 SVN 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] |
|
OpenCV.framework/ |
|
[the framework content] |
|
|
|
The script should handle minor OpenCV updates efficiently |
|
- it does not recompile the library from scratch each time. |
|
However, OpenCV.framework directory is erased and recreated on each run. |
