<p>At [1] , I read Xcode 12 has a new "feature":<br>
<i><br>
<b>Clang</b> now reports an error when you use a function without an explicit declaration when
<span style="color:blue">building C</span> or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on). This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets for this diagnostic. (49917738)</i><br>

<p>At [2], I read that gcc might default to clang with homebrew. If that is the case, have you tried change it to use gcc [3]?<o:p></o:p></p>
<p>If that does not resolve the issue, I'm not a Mac user such that I unfortunately cannot be of much help with that. Perhaps, there is a Mac user in the list that will respond if they have solution for that error.<o:p></o:p></p>
