Here is an example HOWTO to cross compile C/C++ from MacOSX terminal to Windows compatible binaries, using Clang.

Cross-Compile C/C++ Windows and RaspberryPI binaries from MacOSX bash terminal

(Update: RaspberryPI cross compile for cmake has also been added, see source code)

Here is an example Makefile, as well as example cmake platform & toolchains, to cross-compile C/C++ Windows binaries from MacOSX bash terminal, using llvm's clang/lld.

Included are both 32 and 64bit examples for:

• .exe
• .lib (static linked)
• .dll (dynamic linked)
• .dll (dynamic loaded - plugin)

Prerequisites:

• MacOSX High Sierra (or similar)
• MacOSX terminal
• Windows10 installed under Parallels
  • Windows C:\ mounted under MacOSX /Volumes/[C] Windows 10/. This is how clang will find the MSVC compiler lib/ & include/ directories.
• Microsoft Visual Studio 2015 w/ windows sdk (for includes and libs)
• brew install llvm (clang compiler version 6.0.0, or similar)
  • clang/clang++
  • lld
• brew install cmake (cmake version 3.10.3, or similar)
• Optional: Parallels 13 (or similar) - virtualization host running Windows 10
