How to roughly compile this on Visual Studio 2017

• Make sure you got all submodules:

  $ git submodule init
  $ git submodule update
  

• Convert all other Visual Studio solutions to the current version. With FOX, you only need to convert fox.dsp and reswrap.dsp, you can disable all other projects to save time.

• Make sure to consistently set the same C/C++ → Code Generation → Runtime Library option in all projects, because not all of them will come with the same by default.

  Most of them should then compile fine, except…

Fixes for the FOX Toolkit

• Open libs\fox\windows\vcpp\fox\fox.vcxproj in a plaintext editor and remove the following file names from the two reswrap command lines (simply Ctrl-F for reswrap):

  • bigfloppy3.gif
  • bigfloppy5.gif
  • bigharddisk.gif
  • minifloppy3.gif
  • minifloppy5.gif

  Or, simply replace everything matching the regular expression

  (bigfloppy3.gif|bigfloppy5.gif|bigharddisk.gif|minifloppy3.gif|minifloppy5.gif)

  with an empty string.

• Remove the nonexistent FXReactor.cpp from the fox project.

• Set C/C++ → Code Generation → Enable Function-Level Linking to Yes (/Gy) for the Debug configuration of both the reswrap and fox projects.

• Add HAVE_STRTOLL and HAVE_STRTOULL to the list of #define'd preprocessor macros for the fox project at C/C++ → Preprocessor → Preprocessor Definitions.

Fixes for bgmlib

• Make sure to consistently set the same C/C++ → Code Generation → Runtime Library option you also used for the dependent libraries.

• Add SUPPORT_VORBIS_PM to the list of #define'd preprocessor macros at C/C++ → Preprocessor → Preprocessor Definitions. (The other code paths are broken.)

• Point the compiler to the subdirectories of all dependencies by adding the following to the list at C/C++ → General → Additional Include Directories, in this order:

  $(ProjectDir)libs\fox\include\
  $(ProjectDir)libs\ogg\include\
  $(ProjectDir)libs\vorbis\include\
  

• Fix the type error in libvorbis.cpp:
