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 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.

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

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
