QT using OpenCV and camera with mobile phone

[Domididongo]

I have now added this:

osx{

INCLUDEPATH += /usr/local/Cellar/opencv3/3.2.0/include/
LIBS += -L/usr/local/Cellar/opencv3/3.2.0/lib -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_flann -lopencv_features2d -lopencv_imgcodecs -lopencv_ml -lopencv_video -lopencv_videoio
}

ios{
LIBS +=
-F /usr/local/Frameworks/ios
-framework opencv2

}

for the OS X part it works fine. But for the IOS it tells me:
.../opencv2 does not contain bitcode.Your must rebuild it with bitcode enabled (Xcode setting EBALE_BITCODE).

I tried to open the gilded Xcode project and set the Enable Bitcode to NO. But it won't help

Hi,

Did you compile OpenCV for iOS ?

[Domididongo]

I builded the framework like it was said here.

[SGaist]

Which version of Xcode are you using ?

[Domididongo]

I am using Xcode version 8.2.1 and cmake version 3.6.2

[SGaist]

cmake or qmake ?

[Domididongo]

cmake! for building the framework. The QT version I am using is QT5.8.0

[SGaist]

Ok

As for the bitcode problem, I'd modify their python script to ensure that it's building with bitcode enabled.

[Domididongo]

I looked in the '.../opencv/platforms/ios/build_framework.py' file. But which line should I change to enable Bitcode.

In line 47 is the class Builder, if I change 'self.bitcodedisabled = bitcodedisabled' to 'self.bitcodedisabled = 0' should that work?

@Domididongo said in QT using OpenCV and camera with mobile phone:

self.bitcodedisabled = 0

self.bitcodedisabled = False

[Domididongo]

So I changed now in line 276:
parser.add_argument('--disable-bitcode', default=False, dest='bitcodedisabled', action='store_false', help='disable bitcode (enabled by default)')

the action='store_true' to action='store_false',

and in line 58:
self.bitcodedisabled = bitcodedisabled to self.bitcodedisabled = False

but still getting the same error:
does not contain bitcode...

is there somewhere else something i have to change?

Try adding set(CMAKE_XCODE_ATTRIBUTE_BITCODE_GENERATION_MODE "bitcode") to the iOS.cmake file.
