iOS Question Error with B4i Library

walterf25 · 2025-01-21T00:11:34+0000

Hi all, I started wrapping a library, in xcode everything compiles fine, I have generated the xml library file, copied the xml file into the Additional_Libs folder, the library wrapper only has one function as of now, but when i try to compile my app I get the following error

Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_MPPPoseLandmarker", referenced from:
in libiPoseLandmarker.a[2](iPoseLandmarker.o)
"_OBJC_CLASS_$_MPPPoseLandmarkerOptions", referenced from:
in libiPoseLandmarker.a[2](iPoseLandmarker.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The libiPoseLandmarker.a file has been copied to the Libs folder of my local B4iBuildServer along with the MediaPipeTasksVision.framework which is required by this library, Not sure what the error means exactly, hoping someone here with more experience can help me figure this out.

Thanks everyone in advance.

Copying the library isn't enough. Add to your project:

B4X:

#AdditionalLib: iPoseLandmarker.a.3
#AdditionalLib: MediaPipeTasksVision.framework.3

If it works then you can add it to the XML file with:

B4X:

//~dependson: FirebaseAnalytics.framework.3

In the header file.

Hi @Erel I just tried adding

B4X:

#AdditionalLib: iPoseLandmarker.a.3

But I get the following error, I can see that library in the Lib folder of the B4iBuildServer, but not sure why I get this error

ld: library 'iPoseLandmarker.a.3' not found

Any thoughts?

Try:

B4X:

#AdditionalLib: iPoseLandmarker

Hi Erel, just tried that and now I get the following errors.

Error: ** BUILD FAILED **

I have been burning the candle at both ends for almost a week now and can't seem to get this to work, I know you're a busy person but will really appreciate it if I could get some more tips here, I have also created a job post but unfortunately have not gotten any responses, I realize wrapping B4i libraries is a bit more cumbersome than Android libs, I need to get this working or I will loose a client, I really thought it wouldn't be too difficult to wrap this library since I already wrapped the Android one.

Thanks Erel, and anyone else who may have some more insight about why I get the errors I am getting.

I think that you are missing protobuf. Check the library documentation. The dependencies should be listed there.

Just built the ProtocolBuffers library and added it to the Libs folder of my local builder but I still see the same errors.

This is very frustrating.

Building iOS libraries is indeed not simple. Create a new empty project with Xcode and add this framework. Get it running as an app first.
