ruby @1.8.7-p374_10: eval.c:7288:2: error: implicit declaration of function 'rb_thread_join' is invalid in C99 [-Werror,-Wimplicit-function-declaration]

[hellhovnd (Jean-Pierre Chauvel)]

ruby fails to build with Xcode 12.

This would be approximately 1,780,902 ports with the same implicit declaration of function issue :>

[chrstphrchvz (Christopher Chavez)]

As with [d5aee0536e/macports-ports] I suspect there is a change in later Ruby versions which can be backported to fix this issue.

[chrstphrchvz (Christopher Chavez)]

Never mind, rb_thread_join() is being used before but in the same file as its definition.

[chrstphrchvz (Christopher Chavez)]

The ruby port should probably just be removed; 1.8.7 has been EOL for 6 years. What's stopping me from proposing to remove it is how many dependents it still has.

lang/ruby: stop support of ruby-1.8 with macOS 11 or Xcode 12

too many build errors "implicit declaration" with Xcode 12.
ruby-1.8.7 EOLed at July 2014.

see #61255

[kimuraw (kimura wataru)]

I cannot build port:ruby on macOS 11/Xcode 12 for too many compile errors.

I agree to remove EOLed versions of ruby from macports.
