21 нояб. 2010 г. · Is there a safe, portable way to determine (during compile time) the endianness of the platform that my program is being compiled on? I'm writing in C.

2 мая 2018 г. · I have seen many ways to determine at runtime using casting, and some platform-dependent options. Is there a portable or standard way to do this?

10 окт. 2023 г. · If you can determine endianness at compile time, you can create an integer with a given byte representation at compile time.

23 янв. 2012 г. · The only "real" way to detect Big Endian is to use runtime tests. However, sometimes, a macro might be preferred.

7 июл. 2016 г. · Is the endianness of floats and integers a property of the compiled program, such that I can check it at compile time with an assertion somehow?

29 сент. 2016 г. · If you check u1.i == u1.c[0] (same for u2 ) then it works fine. This solution is in many other answers in SO. But those are limited to runtime.

18 окт. 2009 г. · It is not possible to determine endianness at compile time using constexpr (before C++20). reinterpret_cast is explicitly forbidden by [expr.const]p2.

11 нояб. 2008 г. · There is no portable way to do this at compile time, your best bet is probably to use the Boost endian macros or emulate the methods they use.

11 окт. 2017 г. · We want to write endian-independent code in C using some preprocessor directive. Can we define a preprocessor directive which will help us to check endianness ...

16 июн. 2009 г. · There is no way to legally detect endianness at compile time without preprocessor magic. – Richard Hodges. Commented Apr 15, 2016 at 0:24. 1.
