We are trying to install Riak as per the steps mentioned in the website: http://docs.basho.com/riak/latest/installing/source/ but we are getting this error:
Compiling /users/username/riak-2.1.1/deps/syslog/c_src/syslog_drv.c
cc: error: unrecognized command line option '-m64'
ERROR: compile failed while processing /users/username/riak-2.1.1/deps/syslog: rebar_abort
Makefile:22: recipe for target 'compile' failed
make: *** [compile] Error 1
Any suggestion on this will be helpful.
