Supported Platforms

• xmake >= v2.2.2

• Any C++ compiler that supports C++20

Currently, the following platforms and compilers are officially tested.

Note

The 64-bit fixed point number uses eirin::detail::int128_t as the intermediate type. Currently, it depends on the compiler extension, and for the compiler that does not support it, the 64-bit fixed point number will not be available. If you need the 64-bit fixed point number, please use the compiler that supports it or some third-party library to provide the 128-bit integer type (and typedef the fixed64 yourself). In MSVC, the int128_t is typedefed as std::_Signed128 and std::_Unsigned128 in __msvc_int128.hpp header file. And in Linux Clang/GCC, it is typedefed as __int128_t and unsigned __int128_t in __int128_t.h header file.

Integrate into Your Project

A. Copy into Your Project

The core library of EirinFixed is a header-only library, you can copy the include directory into your project, and include the header file in your code.

To be noticed that the header file parse.hpp is not a header-only library, and it includes the interface used for binding fixed point numbers to AngelScript for my another project. If you don’t need it, you can ignore it.

Note

About `papilio_integration.hpp`

This file is used for formatting the fixed point number with PapilioFormat library, which is a C++20 format library. If you want to use it, you need to include the PapilioFormat library in your project. If you don’t need it, you can ignore it.

B. Build and Install with XMake

The library is built with xmake, you can use the following command to build and install the library.
