@ -67,16 +67,25 @@ 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 with GCC: 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.
|
||||
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):
|
||||
|
||||
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, and I
|
||||
have subsequently built OpenTTD successfully this way.
|
||||
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
|
||||
------------------
|
||||
@ -87,42 +96,23 @@ 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, ignore this
|
||||
http://www.zlib.org/
|
||||
|
||||
- libpng
|
||||
http://www.libpng.org/ - contains an EMX/gcc makefile, ignore this
|
||||
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
|
||||
|
||||
If you do not wish to build the libraries yourself, pre-built versions
|
||||
can be downloaded from the Files section at
|
||||
- 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".
|
||||
|
||||
A Note About Subversion Revision Numbers
|
||||
----------------------------------------
|
||||
|
||||
The project file uses a bit of a hack to find out the SVN revision number and
|
||||
create an appropriate rev.c file. You'll need the SVN tools in your path
|
||||
(specifically, "svnversion"). If "svnversion" can't be found, a generic rev.c
|
||||
with the revision set to "norev000" will be created. To specifically force a
|
||||
version number, set the environment variable "RELEASE" to the number (eg, "0.3.6")
|
||||
-before- starting the Open Watcom IDE (which must be launched from the same shell
|
||||
session). Also, beware, as you WILL cause incompatibilities if you try to
|
||||
play a multiplayer game with a different version.
|
||||
|
||||
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.
