So I'm target multiple platforms with one of my c++ projects and on one of the platforms I the window manager is quite different, and one of the libraries can't be used. Thats fine for my needs, I'm just wondering what the typical way to allow for these differences is. Basically currently I've created 2 "main" files that have preprocessor code to only use he one that's right for the platform by having ifdefs at the beginning of each, I've kinda followed that methodology for the other files that are totally platform specific also. Is there a better way to go about this? Currently using msvc for windows compilation and a gcc-esqu compiler for one of the other platforms, where the compile command is built by a home made build tool.
