Header files repeatedly used in different header files in my static library

Question

Since I got multiple classes and utility-functions I reuse on a regular basis, I started to create a static library for those parts. Until now, most of those header files with class and function declarations #include the same "global" header file which itself #includes other header files (like etc.). As for me, It feels annoying to force a user to include more than one header file when only "actively" using the one which got the classes. So I vanquished the global header file and included all the necessary headers into my own headers. This worked in some way, but I encountered some problems regarding Winsock: You need to #define WIN32_LEAN_AND_MEAN and ensure that the user won´t #include before those headers of mine, or multiple redefinitions will occur :/. That´s why I wanted to ask You how You would do this? Or what approches You can think of?

Answer 1

I think you only have the option of defining a general header file that all other header files include and that defines WIN32_LEAN_AND_MEAN. Otherwise you could instruct the user to include such definition in his own files, but his would be error prone. As to inclusion of I think that it will not be included multiple times, since it has "include guards".
