Compilation is taking place in a temporary directory, miles away from
where your org file lives.

The current directory is not specified in the include path.  You would
need to add a -I option to set the (absolute path to the) directory the
org file is in.  If you have all your org files in ~/org, you could try
"g++ -std=c++0x -I~/org".

Hope this helps,
