HOWTO: Compile OpenTTD *without* DirectX SDK

[Valentijn]

Hello,

It's possible to compile OpenTTD without the DirectX SDK installed. The DirectX SDK is only used for game music, so you won't have that after compiling.

Step 1:

Install & configure Visual Studio 2008 express as usual (http://wiki.openttd.org/Microsoft_Visua ... s_Editions).

Skip everything related to the Direct X SDK!

Step 2:

Instruct the preprocessor to not include the code for Win32 music:

Remove WIN32_ENABLE_DIRECTMUSIC_SUPPORT from the preprocessor settings under project properties:

Step 3:

Remove the dxguid.lib from the additional input dependencies for the linker:

Step 4:

Compile as normal in Visual Studio.

Step 5:

Put the original gamefiles (http://wiki.openttd.org/Installation#Files_from_TTD) in bin\data e.g. c:\games\ottdsrc\0.7.5\bin\data.

Step 6:

Run/Debug the game!

EDIT: Fix typo (dxguid.lib)

Instead of step 5 you can also put the needed files in My Documents/OpenTTD/data/, that way they're shared by all your openttd installations and you don't have to copy them to every new installation.

Perhaps you could add those pictures/instructions to this wiki page: http://wiki.openttd.org/MSVC#Microsoft. ... irectX_SDK

thanks, but look closely under the Direct X there is a 'Alternative' section.
where presented mostly the same steps (only there its 'dxguid.lib' and not 'dxguid.dll')

and those pictures are a great help for those who never seen it before
its will be nice if you can update\expand that wiki section, if necessary.

is direct SDX actually nessessary anymore due to the Music Sets being available, or am i just being stupid

[petert]

You could look at it that way, but the MRP isn't complete yet anyway.

Sorry, but didn't the music replacement guys decide they would go for the same format as the TTD (for Windows) music? Wouldn't that imply that the same mechanism for playing them would be used?

[fabca2]

doesn't SDL offert music support and sound too ?
ottd on linux can play music and sound... without directx, no?

I use SDL_mixer on one (little) projet, that allow playing all kind of music format (mp3,mid...) and sound (wav)
is SDL_mixer too limited for ottd or maybe ottd will use something similar in the future ? or not ? (it's just a question for myself, not a suggestion or whatever, I know devs may have many other things to deals with yet)

[Rubidium]

SDL_mixer requires Timidity to play MIDI, OpenTTD's extmidi uses Timidity to play MIDI directly, but can also use aplaymidi and other MIDI playing applications. As such SDL_mixer is totally unneeded for OpenTTD.

DirectX is a Windows native API to play MIDI, why wouldn't we use it? Especially because installing Timidity and SDL on Windows might be cumbersome and you almost certainly have DirectX installed.

Thanks, didn't see that. I corrected the typo as well.

Done.

Thanks, those look great!
