Building on Windows XP with Visual Studio 10

[Kasreyn]

Hello !

I have spent some time now trying to get gbQuake4 to compile on Windows XP SP3 with Visual Studio 10.

You can find my work on branch https://github.com/Kasreyn/gbQuake4/commits/topic/Win32-optimizations/

I added some quality of life things like batch files. These should make the debug process more of a breeze.
Feel free to comment on this and what the issue is with src/precompiled.h (I had to make some changes there).

It compiles in VS10 now, but, I have some issues getting any further than the first menu.
New game / load just leads to a black screen.

I tried copying in q4base from my steam account (and set the STEAM define + recompile) but no improvement.
Any idea what might be wrong?

Are you compiling it as a 32bit app? Currently the 64bit isn't ready and I'm just trying to juggle things around to have time for everything :D

[Kasreyn]

Yes, it is compiling for 32bit Windows XP (running on an Athlon XP 2800+ CPU).

I can get into the game by loading a map so the engine is running OK at least.
For example, by placing "map game/walker" in autoexec.cfg I can get into the game but most of the textures are completely black. Only mountains and some parts on the weapons have visible textures.

As I recall this has something to do with ambient light levels. I think it can be fixed by disabling ambient light? I had this bug before in an official build but forgot under what circumstances I got it.

I will try on mine and see what I get, but I don't remember it being this bad. I've been testing the original release too and I get menus and textures with some of my fixes

[Kasreyn]

I think the issue is that many objects are missing (not getting compiled) from the root of src/game in VS10.
Maybe they were omitted some how? By opening in a different VS..?

Sub folders from src/game are included but not the root files (so we don't get things like Light.cpp compiled into the final binary).

[atsb]

I've only ever tried it on VS2022 so I have no idea.

[Kasreyn]

Sorry for confusion, I was mistaken, root files are already include in "game" sub project.

I'm still confused though because r_forceAmbient doesn't seem to be supported. What happened to it? Was it added in later versions?

I suspect my q4base has the wrong version PAK files because I get a lot of "has version 3 instead of 1.00" warnings from the game, see complete log @ https://pastebin.com/15dfmCm1

This was partially fixed by copying q4base/glprogs into the game's base.

Environment textures are visible but weapons and enemies are still pitch black.

I'm not knowledgeable at all with shaders.
I don't know what should go into glprogs or how to make updates there.
