On Windows, the compiler by default expects an installation of Microsoft Visual Studio Community edition when targeting c++.
However, there's the possibility of using mingw instead, wich is much more quick and lightweight when it comes to installation size and hazzle.
Please keep in mind that mingw isn't the default compiler alternative, and that you might need to dive into the cold c++ sea to get other than basic stuff going.
Setup and usage is very easy:
Installing mingw-w64
See the mingw-w64 download page for details about how to install.
Add -D toolchain=mingw
compiler directive
You also have to add the -D toolchain=mingw
to your project's .hxml file. Here's an example of how a .hxml-file might look:
# build.hxml example using mingw c++ compiler
-cp src
-main Main
-D toolchain=mingw
-cpp bin-mingw
That's it!
