I am trying to build 0.23, I got the error below. I already installed gcc-4.8 and set my alternatives to work with 4.8 as you can see gcc --version returns the right version, where is the configure script pulling that data? Are there flags I could use to help it through the process? :)
John configure: error: GCC 4.8 or higher required (found 4.6.3) darkness@hadoopmapr1:/opt/mapr/mesos/mesos-0.23.0/build$ gcc --version gcc (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1 Copyright (C) 2013 Free Software Foundation, Inc.
