Undefined symbol: _rebind_symbols in new commit 'aadc161ac3b80db07a9908851839a17ba63a9eb1'

I pod install fishhook from github, but an error was reported at building:
Undefined symbols for architecture arm64:
"_rebind_symbols", referenced from:
_main in main.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I found out why is it not compiling successfully.
At the head of rebind_symbols() function there is a macro definition of FISHHOOK_VISIBILITY.
The FISHHOOK_VISIBILITY depends on the FISHHOOK_EXPORT macro definition.
But the FISHHOOK_EXPORT macro definition is not defined.
Thus the state of the rebind_symbols() function is hidden.
You can comment out FISHHOOK_VISIBILITY and it will compile successfully.
