macOS Catalina, version 10.15.7 I reinstalled xcode command-line tools and updated xcode, clang, etc. what should I do for it? thank you.

Hm, I've seen two issues cause this before:

1. clang and ld versions being out of sync.
2. GNU ar, libtool and ranlib overriding Darwin/LLVM ar, libtool and ranlib.

The first shouldn't be an issue per se if you're using Xcode, unless you transferred the project folder from a machine with newer Xcode...? In that case, a make distclean should do the trick.
Otherwise, could you check if any GNU tools override their Darwin/LLVM counterparts?

[cragy0516]

I checked clang and ld versions and it is not problem, maybe. So I tried to check if any GNU tools override their Darwin/LLVM things but with no luck, so I simply changed my account to other user's and it compiled successfully. I don't know still what happend but... it worked :-S

[Siguza]

I'm glad you got it to work.
But hm, I suppose it might be worth to have the Makefile check for this...
