Here's what happened: - You started the thing and the kernel compile complained about an unclean tree. - You ran mrproper. - You tried to run the thing again. amirite? If so, what happened is that mrproper deleted the .o files from the toolchain. Solution: ARCH=powerpc make -C tools/testing/selftests/wireguard/qemu -j$(nproc) clean ARCH=powerpc make -C tools/testing/selftests/wireguard/qemu -j$(nproc) Let me know how that goes. Jason
