Platforms detection

This page mostly concerns the platforms.h header.

Its main purpose in is to let you easily identify which compiler, OS and ISA is being targeted to potentially implement platform-specific code.

Compilers

MSVC

Tested with MSVC v143 from Visual Studio Community 2022.

  • NP_COMPILER_MSVC

CLang

Works, but needs more testing.

  • NP_COMPILER_CLANG

GCC

Works, but needs more testing.

  • NP_COMPILER_GNUC

MinGW

  • NP_COMPILER_MINGW

Supersedes:

  • NP_COMPILER_GNUC

Tiny C Compiler

Tested with Qt's Jom in ReactOS 0.4.14, and nmake on Windows 11 22H2

  • NP_COMPILER_TCC

Unknown

  • NP_COMPILER_UNKNOWN

Platforms & ISA

Windows x64

Tested on Windows 11 22H2 with MSVC.

Windows x86

Tested on Windows 11 22H2 with TCC.

  • NP_OS_WINDOWS

Doesn't compile properly just yet !

  • NP_OS_WINDOWS
  • NP_ARCH_ARM
  • NP_ARCH_ARM_GENERIC

Cygwin

Tested and returned NP_COMPILER_GNUC as the compiler, needs more testing.

ReactOS

Tested on ReactOS 0.4.14 x86.

  • NP_OS_WINDOWS (May change in the future)
  • NP_ARCH_x86

Linux x64

Tested on Kubuntu 23.10 in a VM with GCC & CLang.

  • NP_OS_UNIX
  • NP_OS_LINUX
  • NP_ARCH_x64

Linux x86

Untested.

Linux ARMv8/AArch64/ARM64

Tested on NanoPi R4S with Armbian (23.02.2).

  • NP_OS_UNIX
  • NP_OS_LINUX
  • NP_ARCH_ARM
  • NP_ARCH_ARMv8
  • NP_ARCH_AARCH64

Linux ARM Generic

Untested, will be done soon.

  • NP_OS_UNIX

  • NP_ARCH_ARM_GENERIC

Unknown OS (Apple, ...)

  • NP_OS_UNKNOWN

Unknown ISA

  • NP_ARCH_UNKNOWN

Others

Dynamic library exports

  • NP_DLL_EXPORT

Unicode detection

If UNICODE or _UNICODE are defined, the non-suffixed text-related will have the macro pointing to their unicode variant as is expected on Windows platforms.
