Weird I don't see this one but I only have gcc 12 handy ATM.     gcc version 12.2.1 20230306 (ARC HS GNU/Linux glibc toolchain - build 1360) I even tried W=1 (which according to scripts/Makefile.extrawarn) should include -Werror=implicit-function-declaration but don't see this still. Tomorrow I'll try building a gcc 13.2.1 for ARC. > >> or (alpha) >> >> WARNING: modpost: "saved_config" [vmlinux] is COMMON symbol >> ERROR: modpost: "memcpy" [fs/reiserfs/reiserfs.ko] undefined! >> ERROR: modpost: "memcpy" [fs/nfs/nfs.ko] undefined! >> ERROR: modpost: "memcpy" [fs/nfs/nfsv3.ko] undefined! >> ERROR: modpost: "memcpy" [fs/nfsd/nfsd.ko] undefined! >> ERROR: modpost: "memcpy" [fs/lockd/lockd.ko] undefined! >> ERROR: modpost: "memcpy" [crypto/crypto.ko] undefined! >> ERROR: modpost: "memcpy" [crypto/crypto_algapi.ko] undefined! >> ERROR: modpost: "memcpy" [crypto/aead.ko] undefined! >> ERROR: modpost: "memcpy" [crypto/crypto_skcipher.ko] undefined! >> ERROR: modpost: "memcpy" [crypto/seqiv.ko] undefined! Are these from ARC build or otherwise ? Thx, -Vineet
