I’ve been having the same problems with compiling in OSX 10.7 XCode 4 on many of the addon examples. Here is one specific example but it is the same problem with most addons I’ve tried to compile. I receive an Undefined symbols for architecture i386 link error. I am compiling everything using 10.6, 32bit with oF007. Does anyone know what’s going on?
Thanks

Hi !
I’ve started playing around with openFramweork for a couple of days and start to really enjoy it… But I’m stuck with this error…
Got the same problem when compiling with an addOn (ofxGifEncoder https://github.com/jesusgollonet/ofxGifEncoder ) on os X 10.8.2 and xCode 4.6
What is weird is that when I compile the example provided with the addon it compiles just fine…
does anybody know why we get this error ? It seems like it’s not specific to this addon… please, my project is stuck…
you should see the .cpp files of the addon in there ( compile sources section )
if you don’t can you try re-adding the files to xcode ( drag them into the file section ) and make sure the box is checked for adding the files to the OF app target.
With any of the iOS examples, I can build and run and deploy fine.
With a new project (either a copt of emptyExample or from the Project Generator), as soon as I add ofxiPhone, the linker error appears (but doesn’t if I just have ofxAccelerometer). This happens if I add the addon fro the Project Generator, right-click on the addons folder afterwards, or drag-n-drop the addon onto the project afterwards.
After some reading, I looked into making sure there were no examples included in the Addons (there weren’t), and that the addon was added to the Target (it is). I also see all the files in the build phases - of the target, and also in the oF Xcode project.
Make sure your OF libs are built under the same OSX version. For example if you changed the default the build setting of your project to use 10.7 instead of 10.8 make sure to check your dependencies are also built under 10.7 of you’ll get many linker errors.
Hi. I get here looking about the same error, but I solved it creating a new project and importing the files from the old project. 1 minute solving. Try it.
