ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)



and i really tried many things but couldn't solve these issues.

If I'm not wrong I'm not the only person who got these errors. So please help me if you know any solutions.

Thank you.

 

Using Unity 4.6.1 Xcode 6.1.1 Mac 10.9.5.

 

I have similar problem, if install Yosemite can help?

 

I'm not sure abot this but i think it's about 64-bit support of unity because everything was fine when using armv7.

 

Later on unity will have a update for 4.6 and 5.0 for 64 bit support for ios.

Hi,
I just downloaded Unity 4.6.1f1 and I'm building with XCode 6 but I'm still getting linker errors. Is this version supposed to support arm64 ?

cheers

 

64bit support is not out jet.

Will free unity users get 64-bit support at the end of january?

 

There is no different releases for free and pro, its the same version.

 

It was my mistake. I read it wrong. It says beta version will be available in the middle of january for subscribers and pre-orders.

Thanks by the way.

 

i updated unity to 4.6.1p5 but still getting the same error. am i doing something wrong or less?

 

The same here, I am using 4.6.1p5 I get "Undefined symbols for architecture arm64"

 

i only tried with iOS 7 and i said my problem solved but when i tried with iOS 8 by chance, i saw that only armv7 linker errors were fixed :/ i think it will take time for fully support :/

 

Hi I am also now getting this error for external ObjC code i have written to interface with my Unity game. Help -- stuck?

 

I'm getting this with Unity 5.1.3, XCode 7, iOS9

 

Got this same type of error.
Unity 5.2.1f1 & XCode Version 7.0 (7A220)
Probably caused by not updating to IL2CPP architecture.
