The libretro buildbot ships no aarch64 Linux build of ScummVM, so the core can't be installed from RetroArch's Core Downloader on ARM64 Linux machines (ARM Chromebooks, SBCs, ARM laptops). Nothing blocks it: ScummVM is portable C++ with no x86-specific code on this path, and
android-arm64-v8aalready builds these sources for ARM64.The job mirrors
libretro-build-linux-x64:plus the matching
/linux-aarch64.ymltemplate include, both inbackends/platform/libretro/.gitlab-ci.yml(the repository-root.gitlab-ci.ymlonly includes that file).Verified natively on aarch64 (postmarketOS on a Snapdragon 670 Chromebook, glibc, GCC 15):
make platform=unixinbackends/platform/libretrobuilds the full core with no source changes and without a single error across all enabled engines - 8767 objects, linking toscummvm_libretro.so(ELF 64-bit ARM aarch64, 155 MB unstripped). I didn't run a game through it in this session, so this is a build verification.
