Hi Thomas, We aware the build error, but let it because nfp doesn't support 32-bit. But I just recognized that it is enabled by default on 32-bit default configs, we should disable them. Hi Alejandro, Can you please disable nfp driver explicitly on 'defconfig_i686-native-linuxapp-*' config files, perhaps also on 'defconfig_x86_x32-native-linuxapp-gcc' too? I will drop the existing patch from next-net. And if it is possible to fix the build error, specially if it is just for %lu of the logging, I prefer the fix against the config update, but it is up to you. Thanks, ferruh
