Hi all,

I'm trying to develop a AR prject over UBUNTU 20.04 with AR FUNDATION and ARCORE. i follow this video https://www.youtube.com/watch?v=WIuAyaAtoMQ&t=63s

I downloaded AR FOUNDATION 4.2.2 ARCORE XR Plugin (ARCORE checked) UNIVERSAL RP JAVA openJDK 1.8.0

and i receive these errors

/usr/bin/ld emulation not found aarch64linux emulation supported elf _x86_64 elf32_x86_64 elf_i386 elf_iamcu elf_1om elf_k1om i386pep i386pe

clang error linker command failed with exit code 1
