stdatomic.h: sorry, unimplemented: '_Atomic' in Objective-C

[barracuda156]

Not sure if this is to be fixed in lagrange or rather in the_Foundation:

[skyjake]

The atomic types defined in the_Foundation are also used directly in Lagrange, so the issue affects both the library and the app.

However, I'm not sure what the actual problem is. Should these C11 atomic types be replaced with something else when compiling Objective-C in this configuration?

It seems so from the GCC output. If it looks like a GCC bug to you, I can open a ticket on GCC Bugzilla. Myself I am not sure if those are supposed to be supported in ObjC. But in any case, they do not work as-is.
