Compilation fails with XCode 12
MacPorts can no longer compile CLISP with XCode 12.
.../modules/syscalls/calls.c:626:38: error: implicit declaration of function 'strverscmp' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
begin_system_call(); ret = strverscmp(s2,s1); end_system_call();
^
Implicit declaration of function errors are new in Xcode 12 and the matching command line tools. We should work with the developers to fix them, but if you want to avoid them, downgrade to the Xcode 11.5 command line tools.
Is there an active CLISP developer working with macOS XCode 12 whom I could work with to get this working?
