"The native link step failed" error. Can't build on any platforms.

So I've downloaded a project from a repo but I can't build it. I get a Burst error but I think it's related to X code:

Code (CSharp):

1. BuildFailedException: Burst compiler (1.2.3) failed running
2.  
3. stdout:

I'm working on a Mac with Big Sur 11.1. I recently reinstalled Xcode and Command Line Tools and made sure they were located in the Developers folder following this thread: https://apple.stackexchange.com/que...e-developer-path-when-attempting-to-use-git-a

I'm on Unity 3.14 and Burst 1.2.3. Other projects build just fine, but there's something in this one mucking things up. I've tried some of the Burst suggestions and clicked and unchecked the External Tools boxes. I've reinstalled and restarted everything multiple times. I even had my friend try building it on a Mac without Big Sur and it went fine.

Please help. Thanks!

 

Thanks for writing back Lee! I did try using that version but it ended up giving me even more errors. As follows:

Any help is greatly appreciated!

 

The good news is that it worked! The bad news is that it made the IAP inoperable. Thank you.

 

@Lee_Hammerton do you know of any workarounds for this issue in Unity 2019.2? The thing is that we (like many others) are stuck on Unity 2019.2 since we're doing kids games and about 10% of our user base are stil using older iOS9 devices like the iPad2, so we cannot really update to anything higher than Unity 2019.2.21f1 at the moment.

 

Thanks for the suggestions! The first one didn't work unfortunately. As for the second suggestion, it fails at another stage where the NDK is failing to find the correct linker

Unable to find valid linker at '/Users/Shared/Android/android-ndk-r16b/toolchains/llvm/prebuilt/linux-x86_64/bin/clang'

. So I guess there are more places in the build process that fails due to the fact that the editor thinks it's running on Linux.
