Here's my .dll build script for building in winXP, using VMWare player.
Before install VM tools (the VM drivers) set the VM hardware compatibility to "Workstation 10" (no directx 10, etc)
Menu -> VM -> Manage -> Change hardware compatibility...
cmake 3.13.5
It's kinda hacky but works okay... it builds 4 dirs
debug and release
VM (VM_2GL_HACK_ON on)
Native (VM_2GL_HACK_ON off)
Virtual Box removed 3D support for winXP in v6.1, so I haven't tested it.
Code:
echo off
cls

I'm not sure what the ARB_texture_rg does, but it effects Chicago's background, (deferred rendering only) looks like it's not clearing it.
Looks like EXT_framebuffer_multisample is also used and not supported, but it's not an issue running the samples.
To use the dll's I use tcc (tiny C Compiler)
create dll def files first:
tcc -impdef -v SDL2.dll
tcc -impdef -v libHorde3D.dll
tcc -impdef -v libHorde3DUtils.dll
tcc -impdef -v libstdc++-6.dll
CFLAGS are:
-Wall -Werror -g -I./includes -L. -lSDL2 -llibHorde3DUtils -llibHorde3D -lopengl32
It worked fine with the tutorial

You need to replace this function with the msvcrt friendly version:
In file utPlatform.h
Error: variable 'st rncpy' definition is marked dllimport
comment out the following
// #if (!defined( _MSC_VER ) || (defined( _MSC_VER ) && (_MSC_VER < 1400))) // && !defined( __MINGW32__ )
// # define strncpy_s( dst, dstSize, src, count ) strncpy( (dst), (src), ( ( (count) <= (dstSize) ) ? (count) : (dstSize) ) )
// #endif
add this to the top of the header:
#ifndef _utPlatform_H_
#define _utPlatform_H_
#if (!defined( _MSC_VER ) || (defined( _MSC_VER ) && (_MSC_VER < 1400))) // && !defined( __MINGW32__ )
#include <string.h>
# define strncpy_s( dst, dstSize, src, count ) strncpy( (dst), (src), ( ( (count) <= (dstSize) ) ? (count) : (dstSize) ) )
#endif
function:
inline float toFloat(const char* str)
#ifdef __MINGW32__
// return _atof_l(str, locale.get());
// _atof_l isn't in msvcrt
