Exporting project

[thomasnieren]

Hello,

Thank you for your project who helped me a lot. Now that my model works properly i'm trying to export it into another app, unfortunatly, i'm facing some problems. All the files a compiled but the app cannot be launch. The following issues are thrown by xcode:

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea?

[craftzdog]

Xcode 7 changed its linker rules and it causes linker error with static libraries.
So please try it on Xcode 6.

[thomasnieren]

Ok, but it's working fine with your sample project. I think that i'm missing something, all the errors are about math_functions.

[craftzdog]

Did you add Generate protobuf files in Build Rules section?
Please also check what's missing in the Build Phases and Build Settings of the project.

[thomasnieren]

Thank you, I've just checked and everything seems right. Generate protobuf files is in Build Rules. Build Phases and Build settings are identical to sample-project. I've noticed something but i'm not sure if it matters.

[craftzdog]

hmm,

How about you import your app into this sample?
It's hard to find what's missing.

[thomasnieren]

I forgot to use Accelerate...

[afathi3]

Is there anyway that I can get this working on xcode 7?

[thomasnierenactimage]

It's working on Xcode 7. I suggest you to open a new issue and explain your problem.

[afathi3]

@thomasnierenactimage @thomasnieren I am getting a very similar error to what is stated above.
Xcode complains that the libprotoc.a was built for a different architecture.
