Cross-compile for arm64 (iOS)

[Lukas Kollmer]

I'm trying to run v8 on iOS (arm64).

When I build for arm using `make arm64`, no libv8_base.a file is generated and all generated object files (*.o) are actually for x86. How can I cross compile v8 for arm64?

See cross-compiling instructions at https://github.com/v8/v8/wiki/Cross-compiling%20for%20ARM

iOS is not supported because Apple doesn't allow non-system apps to JIT-compile code, and V8 relies on JIT compilation.

Thanks!

Is iOS not supported because v8 would not compile for iOS or because it wouldn't be allowed by Apple?

I've seen some screenshots of v8 running on iOS 4 or 5 so running on iOS should be possible in theory.

Shouldn't it be possible to compile v8 with the JIT disabled? LuaJIT runs fine on iOS, with the JIT component disabled.

(I don't plan to submit this to the App Store, btw)

You can't disable the JIT, it is required for V8 to run.
