C++ Cross-Platform Predefined Macros

C++ Config (predefined cross-platform macros)

As we know there is no standard way in compilers to standardize macros with compilers and different operating systems

So I created this library that contains standardized macros and built-in functions and more.

---

Contents :

• Compiler
  This section contains some macros that can detect 26 compiler and its version.

• Standard Library
  This section contains some macros that can detect 3 standard libraries and its version.

• Platform
  This section contains some macros that can detect 28 platform.

• Architecture
  This section contains some macros that can detect 16 architecture and its info.

• Attributes
  This section contains some macros that can detect 17 attribute.

• Compiler

  See Online Test to test 5 different compiler's online.

  /*                    Print compiler info                     */
  cout << XEERX_COMPILER              << endl; // 👉 "GCC"
  cout << XEERX_COMPILER_MAJOR        << endl; // 👉 12
  cout << XEERX_COMPILER_MINOR        << endl; // 👉 1
  cout << XEERX_COMPILER_PATCH        << endl; // 👉 0
  cout << XEERX_COMPILER_VERSION      << endl; // 👉 201392128
  
  /*         Check for specific compiler using ID/Macro         */
  #ifdef XEERX_COMPILER_<ID> // for example <ID> = GCC
  ...

• Standard Library

  See Online Test to test 3 different stdlib's online.

  /*                     Print stdlib info                      */
  cout << XEERX_STDLIB                << endl; // 👉 "GNU libstdc++"
  cout << XEERX_STDLIB_MAJOR          << endl; // 👉 2022
  cout << XEERX_STDLIB_MINOR          << endl; // 👉 8
  cout << XEERX_STDLIB_PATCH          << endl; // 👉 19
  cout << XEERX_STDLIB_VERSION        << endl; // 👉 3859283987
  
  /*          Check for specific stdlib using ID/Macro          */
  #ifdef XEERX_STDLIB_<ID> // for example <ID> = GNU
  ...

• Platform

  See Online Test to test 3 different platform's online.

  /*                    Print platform info                     */
  cout << XEERX_PLATFORM              << endl; // 👉 "Linux"
  cout << XEERX_PLATFORM_FAMILY       << endl; // 👉 "POSIX"
  
  /*         Check for specific platform using ID/Macro         */
  #ifdef XEERX_PLATFORM_<ID> // for example <ID> = LINUX
  ...
  
  /*     Check for specific platform family using ID/Macro      */
  #ifdef XEERX_PLATFORM_FAMILY_<ID> // for example <ID> = POSIX
  /* this platform is belong from POSIX */
  ...

• Architecture

  See Online Test to test 2 different architecture's online.

  /*                  Print architecture info                   */
  cout << XEERX_ARCH          << endl; // 👉 "x86_64"
  cout << XEERX_ARCH_SIZE     << endl; // 👉 64
  cout << XEERX_ARCH_ENDIAN   << endl; // 👉 "LITTLE"
  
  /*       Check for specific architecture using ID/Macro       */
  #ifdef XEERX_ARCH_<ID> // for example <ID> = XEERX_ARCH_X86_64
  ...
  
  /*   Check for specific architecture family using ID/Macro    */
  #ifdef XEERX_ARCH_FAMILY_<ID> // for example <ID> = X86
  /* this architecture is belong from X86 */
  ...

• Attributes

  XEERX_ATTR_INLINE
  XEERX_ATTR_HIDDEN
  XEERX_ATTR_DEPRECATED("old version")
  void func(int x, int y)
  ...
