Semantic Issue: heartbeatTimer from OEContinuousModel.h shows Error

[paulranico]

Hi,

I’m new in Open Ears and downloaded the demo version of the RapidEars and NeatSpeech to try to learn and implement it and make it work before purchasing it, I’m on a learning level yet so I’m unfamiliar on some other codes.

I’ve been following the guide in https://www.politepix.com/openears/tutorial and then there comes an error when I started building it. It says “Property with ‘retain (or strong)’ attribute must be of object type” it is on OpenEars.framework>Headers>OEContinuousModel.h>heartbeatTimer, “@property (nonatomic, strong) dispatch_source_t heartbeatTimer;”

Can you help me figure what what I am missing.

Thanks in Advance

Welcome,

Something fundamental would be wrong in that case, because you could only get that error if you were building the framework or linking to that header, but that isn’t part of the tutorial. I would recommend starting over with a fresh download.

Hi Halle,

Thanks for that really quick reply, I have redownloaded and rebuilt the app but it still shows errors. I’m working on an app ported in Unity3d it works with the old implementation of OpenEars. But now, We want to create a realtime recognition, so we have to upgrade API and I haven’t changed any of the codes yet. So It’s a bit confusing why this happens. Somehow, It’s only on the xCode part where it doesn’t build.

Sorry, this is about the Unity3D implementation, not OpenEars. I don’t support it.

Hi,

Ok, I’ll try to find it out myself, but for last question/assist can I post the error log that I’m having, I can build a “normal realtime” app but when I try to change the pocketSphinx to “listenRealtime” using rapid sphinx it terminates the app and shows this error

do you have any Idea why it happens?

Thanks so much!

[Halle Winkler]

Most likely the issue is that your project lacks the -ObjC ‘other linker flag’ described in the installation docs.

[paulranico]

Yes! it worked! Thank you very much Halle.

[Halle Winkler]

Glad to hear it! You’re welcome.

heartbeatTimer issue occurs if you set your deployment target to iOS 5.1.1.

Workaround: set deployment target to at least iOS 6.0.

[Halle Winkler]

6.1.1 is the minimum supported version currently.
