OpenTTD: OS/2 version
|
|
=====================
|
|
|
|
OpenTTD has been ported to work on OS/2 4.x or later (including
|
|
eComStation). The game should work as well as it does on Windows
|
|
or other platforms: the main issues you may encounter are graphics
|
|
card problems, but that is really the fault of SDL.
|
|
|
|
=========================
|
|
USING OPENTTD FOR OS/2
|
|
=========================
|
|
|
|
LIBRARIES REQUIRED FOR END USERS
|
|
--------------------------------
|
|
|
|
SDL.DLL (SDL 1.2.7) and FSLib.dll are required to use this program:
|
|
these can be downloaded from the Files section at
|
|
http://sourceforge.net/projects/openttd/ - see "os2-useful-v1.1.zip".
|
|
Version 20051222 of SDL or later is required. This can be found at
|
|
http://sdl.netlabs.org/.
|
|
|
|
Please note that earlier SDL releases will probably NOT work with
|
|
OpenTTD. If you experience problems with OpenTTD, please check
|
|
your SDL and FSLib.dll versions (both must match).
|
|
|
|
Note that to actually play the game, I have found in my own
|
|
experience that a version of the Scitech Display Drivers or its later
|
|
incarnation (see www.scitech.com) are necessary for it to work. If
|
|
you have trouble with your native drivers, try the Scitech drivers
|
|
and see if they help the problem.
|
|
|
|
KNOWN ISSUES
|
|
------------
|
|
|
|
- If an error occurs during loading, the OS/2 error message window
|
|
is not always displayed.
|
|
|
|
A NOTE ABOUT MUSIC
|
|
------------------
|
|
|
|
OpenTTD includes a music driver which uses the MCI MIDI system. Unfortunately,
|
|
due to the lack of proper MIDI hardware myself, I have been unable to test it,
|
|
but during testing, I found that when MIDI was enabled, I got no sound
|
|
effects. I therefore decided to DISABLE music by default.
|
|
|
|
To enable music, start OpenTTD with the command line:
|
|
|
|
openttd -m os2
|
|
|
|
If I hear enough responses that both music and sound work together (it might
|
|
just be my system), I'll have the defaults changed.
|
|
|
|
A NOTE ABOUT DEDICATED MULTIPLAYER SERVERS
|
|
------------------------------------------
|
|
|
|
To start a dedicated multiplayer server, you should run the dedicated.cmd
|
|
file. This enables OpenTTD to open up a VIO console window to display
|
|
its output and gather any necessary input. Running "openttd -D"
|
|
directly will result in the console not being displayed. You may
|
|
still pass any other parameters ('-D' is already passed) to
|
|
dedicated.cmd.
|
|
|
|
=========================
|
|
BUILDING THE OS/2 VERSION
|
|
=========================
|
|
|
|
Compiler
|
|
--------
|
|
|
|
Innotek GCC, an OS/2 port of the popular GCC compiler, was used to build OpenTTD.
|
|
See www.innotek.de for more information. You WILL need a reasonably UNIX-like
|
|
build environment in order to build OpenTTD successfully - the following link
|
|
may help to set one up (although some of the links from that page are broken):
|
|
|
|
http://www.mozilla.org/ports/os2/gccsetup.html
|
|
|
|
To build, you should, if your environment is set up well enough, be able to just
|
|
type `./configure' (or `sh configure' if you're using the OS/2 shell) and `make'.
|
|
|
|
A note on Open Watcom
|
|
---------------------
|
|
|
|
Open Watcom C/C++ was previously used to build OpenTTD (version 0.4.x and earlier).
|
|
However, due to advanced C++ features used in the YAPF portion of OpenTTD 0.5
|
|
in particular, the compiler is no longer able to build the game at the moment.
|
|
Hopefully one day Open Watcom will be able to catch up and we will be able to build
|
|
the game once again (it's easier than getting an OS/2 UNIX-like environment set up
|
|
in my opinion!), but until then, OpenTTD 0.5 and later can only be built with GCC.
|
|
|
|
Libraries Required
|
|
------------------
|
|
|
|
The following libraries are required. To build zlib and libpng, I
|
|
simply added the required files (watch out for sample programs, etc)
|
|
to an IDE project file and built a library. Do not use the makefiles
|
|
provided, they are not designed for Watcom (apart from SDL):
|
|
|
|
- zlib
|
|
http://www.zlib.org/
|
|
|
|
- libpng
|
|
http://www.libpng.org/
|
|
|
|
- SDL for OS/2
|
|
ftp://ftp.netlabs.org/pub/sdl/sdl-1.2.7-src-20051222.zip used for
|
|
0.4.7
|
|
|
|
- Freetype
|
|
http://freetype.sourceforge.net/
|
|
|
|
Currently, there are no pre-built libraries available for GCC. If you manage to get
|
|
OpenTTD working on Watcom though (do let us know if this is the case!), pre-built
|
|
versions can be downloaded from the Files section at
|
|
http://sourceforge.net/projects/openttd/ - see "os2-useful-v1.1.zip".

Thanks to Paul Smedley for his help with getting OpenTTD to compile under GCC on OS/2.
