Xcode 4 Error: Undefined symbols for architecture i386

[SBA]

Hi people,

After switching Xcode 4 and oF7 I am haunted by Apple Mach-O Linker (Id) Error..

I can run examples, but whenever I try to create a new project (and add something from addons), I immediately get this error...


The log looks like this:

ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status

This log is from ofxDelaunay but I get the same when I try to add OpenCV to new Empty Example..


I tried all the solutions I could find (one by one, altogether and in all possible combinations) such as..

1) Setting Symbol Hidden by Default  to YES (for both example scheme & of scheme)
2) Clean build
3) Changed build architecture..
4) Compared Build Setting of example and new project line by line..

Apparently it's some Xcode4 nuance, that I'm missing...  Can somebody please point out..?

Getting the same error in XCode 4 with OpenNI. Will post if I figure it out.

Did you ever figure this out?

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...

can you check the build phases section of the target settings ( not OF but see image here for where it is http://www.thinketg.com/Images/Frameworks-2.jpg ) ?

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.
