ofxCv examples won't compile in Xcode!


I’ve been trying all evening to get ofxCV examples to compile with Xcode. Every time I get the following 2 errors:

! “_vImageConvert_BGRA8888toRGB888”, referenced from:
-[QTKitVideoGrabber update] in openFrameworksDebug.a(ofQTKitGrabber.o)
Symbol(s) not found for architecture i386
! Linker command failed with exit code 1 (use -v to see invocation)

Any ideas??

I downloaded the latest build from github, renamed it to just “ofxCV” and am running the examples in their original folders. I’m using Xcode 4.6 , ofx 7.4 and Mac OS 10.7.

Sorry if this is something obvious - I am quite new to OpenFrameworks - but I have been googling for ages with no luck.



Hi Leo,

You should read this: http://forum.openframeworks.cc/t/[solved]-qtkitvideograbber-linker-fail-targeting-osx-10.7/12751/0

The problem is that OpenFrameworksLib.xcodeproj has different target SDK from your OS, so try to set the target SDK to 10.7.

I think this problem must be documented in tutorial.
