In case of arm, for at least clang 5 - 10 it causes error like: clang: warning: unknown platform, assuming -mfloat-abi=soft LLVM ERROR: Unsupported calling convention make[2]: *** [/home/root/snapshot/samples/bpf/Makefile:299: /home/root/snapshot/samples/bpf/sockex1_kern.o] Error 1 To make the platform to be known, only set to real triple helps: --target=arm-linux-gnueabihf or just drop the target key to use default one. Decision to just drop it and thus default target will be used, looks better.
