The RubyInstaller build tools are fantastic! Unfortunately I fail at exactly the same spot, undefined reference to __sync_val_compare_and_swap_4. Looking closer, ruby_atomic.h checks HAVE_GCC_ATOMIC_BUILTINS and assumes the one I need is there even though it is missing. There is a check in configure for linux for this builtin, but not for mingw32. Removing HAVE_GCC_ATOMIC_BUILTINS from config.h allows linking of miniruby ---------------------------------------- Feature #7427: Update Rubygems https://bugs.ruby-lang.org/issues/7427#change-34246 Author: mame (Yusuke Endoh) Status: Closed Priority: Urgent Assignee: drbrain (Eric Hodel) Category: Target version: 2.0.0 Eric Hodel is planning to update Rubygems by the end of November.
