S01 Libvpx [updated] — Cross

Now run a decode test on the S01:

Explicitly disable everything your target doesn't have. cross s01 libvpx

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 . Now run a decode test on the S01:

Make sure your environment variables are clean: On Linux ARM64, you need to ensure you

ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked Perfect.

Here is the magic incantation for the S01 (Cortex-A53):

That’s where (System 01 / Stage 01) comes in. But today isn't about the hardware; it's about the codec that makes the web go round: libvpx (VP8/VP9). Cross-compiling this beast isn't just a ./configure --host=arm . It’s a dance with intrinsics, neon flags, and the ghost of floating-point quirks.
