Here is the magic incantation for the S01 (Cortex-A53):
undefined reference to `aarch64_linux_get_cpu_flags' Why? Because libvpx’s assembly stubs for runtime detection expect an OS-specific function. On Linux ARM64, you need to ensure you built with the right AS (assembler) and that --enable-runtime-cpu-detect is paired with the correct --target . cross s01 libvpx
Cross-compiling turns that 45 minutes into . But only if you know the incantations. Step 2: The Toolchain Trap You need a cross-compiler. For S01 (Cortex-A53), I recommend aarch64-linux-gnu-gcc . Here is the magic incantation for the S01
If you’ve ever tried to build video processing software for embedded Linux, you know the pain. You write beautiful code on your Ryzen workstation, only to watch the Raspberry Pi (or similar SBC) throttle its CPU to 600MHz halfway through a make -j4 . Cross-compiling turns that 45 minutes into
