Hi again Fred, I tried your suggestion >> otool -L /Users/Humberto/riak-2.1.1/rel/riak/bin/../lib/eleveldb-2.1.0-0-ga36dbd6/priv/eleveldb.so
And I obtain your same output >> /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 104.1.0) >> /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0) So, then I am using clang/LLVM instead of GCC? I was thinking that I was using GCC because of this: ------------------------------------------------------ Humbertos-MacBook-Pro-2:Humberto$ gcc -v Using built-in specs.
