title: GCC to compile compile 64 bit
body: <p>I'm trying to compile C++ with G++ in 64 bit.</p>
  
  <p>I'm using sublime text 3. This is my build system file : </p>
  
  <pre><code>{
    "cmd": ["g++ ", "-m64", "-std=c++0x", "$file", "-o", "${file_path}/${file_base_name}"],
    "file_regex": "^(..[^:]*):([0-9]+):?([0-9]+)?:? (.*)$",
    "working_dir": "${file_path}",
    "selector": "source.c, source.c++, source.cxx, source.cpp",
    "variants": 
    [ 
      {
        "name": "Run",
        "cmd": ["bash", "-c", "g++ -m64 -std=c++0x '${file}' -o '${file_path}/${file_base_name}.exe' &amp;&amp;  xterm -e bash -c '\"${file_path}/${file_base_name}.exe\" ; read'"]  
      }
    ]    
  }
  </code></pre>
  
  <p>Compiled files are still created as 32 bit. 
  When I run g++ <code>--print-multi-lib</code> I get:</p>
  
  <pre><code>32;@m32
     x32;@mx32
  </code></pre>
  
  <p>I'm sure this has something to do with it, but I'm not sure how to fix it, (Pretty new to this), I've tried installing multilib 64 but nothing has changed. </p>
  
  <p>Any help appreciated. Thank you :)</p>
