I have been getting a similar error. Here is the first error that popped up. source/mon-info.h:356:9: error: 'function' does not name a type; did you mean 'union'? The first warning looking something like this.

source/externs.h:404:53: warning: dynamic exception specifications are deprecated in C++11 [-Wdeprecated]
