WindowsやLinuxなどの複数のプラットフォーム用にC++アプリケーションを作成する場合、プラットフォームコードを作成するための推奨される方法は何ですか？このタスクを実行するために、どのようなパターン、クラス階層などが存在しますか？コード、ヘッダー、ソースファイルをどのように整理する必要がありますか？

I don't get your question completely, but generally you should separate your platform dependent code from platform independent one. for example you may have a folder platform and inside it a folder for each platform that supported by you, then you may have win32/mutex.hpp, linux/mutex.hpp, mac/mutex.hpp and in each of them you may add implementation of mutex for that platform. Then all you need is a single selector header that based on platform select correct file and include it. For example platform/mutex.hpp that include any of specified files in correct platform.

But beside that, take a look at boost it implement many platform dependent code in a platform independent manner, you can learn from it and you may see implementation of your platform dependent code there!!

  1. Stick to standards defined by C++ ISO specifications.
  2. Use PLATFORM independent libraries (like Boost and Qt and Fltk)

  3. Make sure you don't use COMPILER specific extensions, or atleast stick to 1 SINGLE compiler(recommended: G++ which is cross platform)

    Follow these first. Patterns are but means of organising code. Standard patterns allowed by a language theoretically remain the same across all platforms, so that shouldn't be a part of the problem

  4. Use #ifdef MACROS to code platform specific path to files, platform specific libraries for networking etc.

More you remain platform independent, more you will have to rely on third party toolkits.

Organization:

FOLDERS: program
         |_plaf
         |_headers
         |_source
         |_makescripts

plaf
|_win32 //contains windows specific wrapper functions in header files
|_unix  //contains unix specific wrapper functions in header files

headers: //contains platform independent headers
lib: //contains platform independent static libraries
sources: //contains .h and .cxx(or .cc or .cpp) files. ONE file per class with main function in main.cxx
