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.zip".
|
|
(Note that a newer version of SDL is now available at
|
|
ftp://ftp.netlabs.org/pub/sdl/sdl-dev-os2-2004-12-22.zip which may
|
|
help solve some problems).
|
|
|
|
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
|
|
--------
|
|
|
|
Open Watcom 1.3 was used to build OpenTTD (earlier versions will
|
|
NOT work). See http://www.openwatcom.org/ to download it. It may
|
|
also be possible to build OpenTTD under OS/2: I attempted this
|
|
before using Open Watcom, but found the tools available for OS/2
|
|
at the time to be a bit more tricky to get working.
|
|
|
|
Due to complexities in my set-up, I actually used the Win32 version
|
|
of Open Watcom to initially compile OpenTTD for OS/2. There should
|
|
be no reason of course why the OS/2 version cannot be used.
|
|
|
|
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/ - contains a makefile for OS/2, but is out
|
|
of date and uses EMX
|
|
|
|
- libpng
|
|
http://www.libpng.org/ - contains an EMX/gcc makefile
|
|
|
|
- SDL for OS/2
|
|
For 0.3.5, I used ftp://ftp.netlabs.org/pub/sdl/SDL-1.2.7-src-20040908a.zip -
|
|
take SDL.dll and SDL.lib from the src/ directory. Note that 20041222 is
|
|
out now, which is recommended for stability updates.
|
|
|
|
If you do not wish to build the libraries yourself, pre-built versions
|
|
can be downloaded from the Files section at
|
|
http://sourceforge.net/projects/openttd/ - see "os2-useful.zip".
|
|
|
|
Compiling
|
|
---------
|
|
|
|
To compile, open the os/os2/openttd.wpj file in the IDE and first build
|
|
the strgen.exe target. This will build the .lng file generator, and will
|
|
also attempt to build all the language files (plus the table\strings.h
|
|
file which is required for openttd.exe to be built). Once strgen.exe and
|
|
the language files are built successfully, you can build the openttd.exe
|
|
target.
