An error is received when running the build script for Berkley DB XML 2.5.16 in Ubuntu 12.04 with vagrant on a virtualbox:
../include/xqilla/framework/XPath2MemoryManager.hpp:90:11: error: 'ptrdiff_t' does not name a type
make[1]: *** [ReferenceCounted.lo] Error 1
make[1]: Leaving directory `/usr/share/dbxml-2.5.16/xqilla/build'
Resolution was to add the following line after line 26 to the file XPath2MemoryManager.hpp:
#include <cstddef>
The full path to the file is:
/usr/share/dbxml-2.5.16/xqilla/include/xqilla/framework/XPath2MemoryManager.hpp
