Minimall supported build without boost.
To remove boost dependency, `-DMSGPACK_USE_BOOST=OFF` for cmake. By default, `-DMSGPACK_USE_BOOST` is `ON`. NOTE: In order to build tests `-DMSGPACK_USE_BOOST=ON` is required. For C++ compiler, the option `-DMSGPACK_NO_BOOST` is required to remove boost.

[heading `MSGPACK_ENDIAN_*`]
|
||||
|
||||
Detection of endian memory ordering. There are four defined macros
|
||||
in this header that define the various generally possible endian
|
||||
memory orderings:
|
||||
|
||||
* `MSGPACK_ENDIAN_BIG_BYTE`, byte-swapped big-endian.
|
||||
* `MSGPACK_ENDIAN_BIG_WORD`, word-swapped big-endian.
|
||||
* `MSGPACK_ENDIAN_LITTLE_BYTE`, byte-swapped little-endian.
|
||||
* `MSGPACK_ENDIAN_LITTLE_WORD`, word-swapped little-endian.
|
||||
|
||||
The detection is conservative in that it only identifies endianness
|
||||
that it knows for certain. In particular bi-endianness is not
|
||||
indicated as is it not practically possible to determine the
|
||||
endianness from anything but an operating system provided
|
||||
header. And the currently known headers do not define that
|
||||
programatic bi-endianness is available.
|
||||
|
||||
This implementation is a compilation of various publicly available
|
||||
information and acquired knowledge:
|
||||
|
||||
# The indispensable documentation of "Pre-defined Compiler Macros"
|
||||
[@http://sourceforge.net/p/predef/wiki/Endianness Endianness].
|
||||
# The various endian specifications available in the
|
||||
[@http://wikipedia.org/ Wikipedia] computer architecture pages.
|
||||
# Generally available searches for headers that define endianness.
