[solved] linker errors opencvExample fails to load webcamera on OSX

examples
#1

Hi All

I’m checking out the included examples. I’m running Lion building as 10.7.

My webcam failed to load on my Mac Air:

// testApp.h
//#define _USE_LIVE_VIDEO // uncomment this to use a live camera

Undefined symbols for architecture i386:
“_vImageConvert_BGRA8888toRGB888”, referenced from:
-[QTKitVideoGrabber update] in openFrameworksDebug.a(ofQTKitGrabber.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is BGR supported?
Did I forget to configure something in Xcode for OF. Sorry I’m new.
BTW does your site list in short summary what each of these samples do?

I’m also seeing a workspace integrity error for many of the examples.

I solved the problem by following this.

Maybe there should be note provided in the tutorials to warn about how changing default build settings of one example needs to be reflected in the defaults of all linked libs. Easy to miss for us noobs.
