Rails bundle update keeps failing on processing atomic gem v 1.1.16. Have searched the web back and forth for solution. Checked gcc --version:
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include- dir=/usr/include/c++/4.2.1
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix
Installed xcode command lines, ran gem system updates, uninstalled previous atomic versions and tried to reinstall 1.1.16. Same result:
...
clang: error: unknown argument: '-multiply_definedsuppress' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
make: *** [atomic_reference.bundle] Error 1
make failed, exit code 2
Does anybody have a hint? Thanks in advance.
UPDATE
These are the nearest to solution I have found so far from google groups and github.
Seems to be a yet unsolved issue of osx Mavericks and/or Xcode. But the modified bundle install hint at least gets it to run complete.
