[edit] Introduction

This page contains guidelines for compiling OpenTTD in Win32 with MinGW and Dev-C++.

Note: this how to is outdated. Dev-C++ is currently not supported by OpenTTD.

[edit] Information

• Source tested: OTTD r1238.
• Packages used here:
  • MSYS-1.0.10
  • MinGW-3.1.0-1
  • binutils-2.15.91-20040904-1
  • gcc-core-3.4.2-20040916-1
  • gcc-g++-3.4.2-20040916-1
  • mingw-runtime-3.5
  • w32api-3.1
  • zlib-1.2.1
  • DirectX9 for Dev-C++ from http://www.devlib-central.org/mambo/index.php?option=com_remository&Itemid=12&func=selectcat&cat=4 (FIXME this link is broken)
  • Dev-C++-4.9.9.1 (with compiler)
• Others
  • SDL will not be used here.
  • SVN will not be used here, however it is recommended to have it.

[edit] Setting up Environment

Set up MinGW and zlib. Please refer to Setting up MinGW and Compiling zlib.

Install Dev-C++ from http://www.bloodshed.net/dev/index.html.

Follow the instrutions on http://www.gamedev.net/reference/articles/article2067.asp to get DirectX (DirectMusic) to work.

[edit] Configure compiler

1. Run Dev-C++.
2. In Tools -> Compiler Options
   • Add Compiler set "MinGW".
   • In directories tab, remove all directories in all sessions. Just add (mingw)\bin in "Binaries". Change (mingw) into your MinGW installation.
   • Click "OK".

[edit] Compiling strgen

You need tables/strings.h created by strgen to compile OpenTTD.

1. Import ./strgen/strgen.dsp into Dev-C++.
2. Press Ctrl+F9 to compile.
3. Copy the newly created strgen.exe to the main directory where you installed the OpenTTD source.
4. Run strgen.exe from there. It should create table/strings.h.

[edit] Compiling OTTD

If you cannot compile, DON'T PANIC. Sometimes it may be due to coding errors.

1. Import the "ttd.dsp" to Dev-C++. Use "ttd - Win32 Release". Ignore the error about missing files.
2. Wait for parsing.
3. In Project -> Project Options.
   • Under the Compiler tab, choose "MinGW" as compiler.
   • Under the Parameters tab, add -DINITGUID to both the C and the C++ compiler options.
   • Click "OK".
4. Create Makefile.config by Execute -> Clean.
5. Add Makefile.config the into project. Modify the file by changing the following parameters:
STATIC:=
WITH_ZLIB:=1
WITH_SDL:=
STATIC_ZLIB_PATH:=/mingw/lib/libz.a
WIN32:=1
UNIX:=
OSX:=
FREEBSD:=
MORPHOS:=
BEOS:=
SUNOS:=
CYGWIN:=
MINGW:=1

   Some slots are made empty to disable.

6. Compile the project.
7. The compile was successful if you see a new openttd.exe file appear in the folder.

[edit] Testing OTTD

1. Copy the following files from (TTD)\data\ to (OTTD)\data\:
   sample.cat
trg1r.grf
trgcr.grf
trghr.grf
trgir.grf
trgtr.grf
2. Run openttd.exe.
3. Enjoy!
