+config BR2_PACKAGE_PUGIXML_WCHAR_MODE
+	bool "Enable wchar_t mode"
+	help
+	  Toggles between UTF-8 (default) style interface (the in-memory
+	  text encoding is assumed to be UTF-8, most functions use char
+	  as character type) and UTF-16/32 style interface (the
+	  in-memory text encoding is assumed to be UTF-16/32, depending
+	  on wchar_t size, most functions use wchar_t as character type)

+config BR2_PACKAGE_PUGIXML_COMPACT
+	bool "Enable compact mode"
+	help
+	  Activates a different internal representation of document
+	  storage that is much more memory efficient for documents with
+	  a lot of markup (i.e.  nodes and attributes), but is slightly
+	  slower to parse and access.

+
+config BR2_PACKAGE_PUGIXML_NO_XPATH_SUPPORT
+	bool "Disable XPath support"
+	help
+	  Disables XPath support in pugixml. Both XPath interfaces and
+	  XPath implementation are excluded from compilation. This
+	  option is provided in case you do not need XPath functionality
+	  and need to save code space.
+
+config BR2_PACKAGE_PUGIXML_NO_STL_SUPPORT
+	bool "Disable STL support"
+	help
+	  Disables use of STL in pugixml. The functions that operate on
+	  STL types are no longer present (i.e. load/save via iostream)
+	  if this macro is defined.  This option is provided in case
+	  your target platform does not have a standard-compliant STL
+	  implementation.
+
+config BR2_PACKAGE_PUGIXML_NO_EXCEPTIONS
+	bool "Disable exceptions"
+	help
+	  Disables use of exceptions in pugixml. This option is provided
+	  in case your target platform does not have exception handling
+	  capabilities.
+
+config BR2_PACKAGE_PUGIXML_HEADER_ONLY
+	bool "Enable header-only version"
+	help
+	  All source code for pugixml will be included in every
+	  translation unit that includes pugixml.hpp. This is how most
+	  of Boost and STL libraries work.
+
+	  http://pugixml.org/docs/manual.html#install.building.header
+
+config BR2_PACKAGE_PUGIXML_HAS_LONG_LONG
+	bool "Enable long long support"
+	help
+	  Enables support for long long type in pugixml. This define is
+	  automatically enabled if your platform is known to have long
+	  long support (i.e. has C++11 support or uses a reasonably
+	  modern version of a known compiler); if pugixml does not
+	  recognize that your platform supports long long but in fact it
+	  does, you can enable the define manually.
