Do you mean that eventually clang is going to make C23 the default too? Yeah, considering this it's a good idea to specify the standard explicitly. I am not sure what's the best choice though. If the tests compile currently with gnu17, maybe we can leave it at that, and not fall back to gnu11? > I tried adding -std=gnu11 to both host and bpf side flags: > test_progs, test_verifier, test_maps, veristat compile ok. > > > define GCC_BPF_BUILD_RULE > > $(call msg,GCC-BPF,$4,$2) > > - $(Q)$(BPF_GCC) $3 -DBPF_NO_PRESERVE_ACCESS_INDEX -Wno-attributes -O2 -c $1 -o $2 > > + $(Q)$(BPF_GCC) $3 -O2 $(GCC_BPF_CFLAGS) -c $1 -o $2 > > endef > > > > SKEL_BLACKLIST := btf__% test_pinning_invalid.c test_sk_assign.c
