Ad hoc build - screen goes black when tracking target

January 27, 2012 - 4:21am #1

Hi,

I'm having a problem when running an Ad hoc build made for distribution. The app starts up fine, but when an image target is recognized the EAGLView goes black.

When building directly to my device from XCode everything works as expected. The only difference is the Code signing identity.

Has anyone seen this behaviour before, and if so, how did you solve it?

Well found - I'll add that to The Book of Possibilities. :-)

Ah, it turned out to be a simple newbie misstake - missed to set the Preprocessor Macros for Ad-Hoc - so once the image got tracked OpenGL went bezerk...

Many thanks for trying to help me, I've learned a lot by reading your answers to other posters!

Try building for Release on Xcode and run that, so that you know you're running the same compiled code, to see if you can reproduce the problem from where it can be better observed.

We've not seen this before but we're not in the habit of doing AdHoc distributions.

Can you reproduce this with a sample app, such as ImageTargets?

I'm using 1.0.0 (I guess that's the only one that's not in a beta phase?). It's really strange - if I run the code on my device from XCode everything works like a charm.

Hi Cidde, can you confirm which version of QCAR you are using?
