The messages followed by "Reason: Image not found"

Additional info: Both iMac and M1 MacBook otool info are: ***: /lib/usr/libSystem.B.dylib locate libSystem.B.dylib /application/Xcode/xxxxxxxxxxxxxxxxxxxxxxxxx/libSsytem.B.dylib

And I tried  -lSystem -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib posted on the other questions and no luck. On the iMac clang without any options like clang -o *** *.c

In case someone can help: 1 All the basic c code can be compiled and ran on iMac(Big sur 11.1) without additional lib (clang -o mycode mycode1.c mycode2.c) 2 M1 macbook(Big sur 11.1) can run basic helloworld.c binary code but failed when I test binary with multi c code files, like clang -o mycode mycode1.c mycode2.c 3 Both iMac and M1 macbook air don't have any compiling issues 4 Error message "Library not loaded: usr/lib/libSystem.B.dylib" "Reason: Image not found" 5 otool -L mycode on both iMac and M1 macbook Air: "/lib/usr/libSystem.B.dylib" 6 locate libSystem.B.dylib on both iMac and M1 macbook Air: /application/xcode.app/xxxxxxx/appletvos(watchos/iphoneos)/xxxxxxxxxxxxxxxxx/libSystem.B.dylib 7 M1 installed xcode twice, and clang - 1200.0.32.28, ld64-609.8

For those who might have the same issue: 1 It's a problem of Big sur or xcode, I refresh my disk with brand new big sur 11.1 and no problem at all. 2 I am disappointed with Apple support because they transferred my case and no one was able to handle it. 3 Apple guys in here may think my question is stupiid they just didn't want to answer.
