# Installation

## u61 and u61-data

### u61

The "u61" package contains:

- The u61 executable file. The one you have to run to play the game.
- A pre-compiled theme. More themes are available in "u61-data".
- Some sample scripts. More scripts are available in "u61-data".
- Documentation in one single format. Other formats (PostScript, PDF) are available in "u61-data".

Basically, "u61" is the only required package since it contains the executable and some pre-compiled stuff so that the game runs. It contains enough to give you a quick start with U61, and allows you to play without downloading tons of graphics with a 56K modem 8-)

If you download U61 from CVS, note that the CVS version does not contain any script or theme file, and almost no documentation at all. In fact, the packaged releases of the u61 package contain pre-compiled files imported from the u61-data package.

### u61-data

The "u61-data" package contains:

- More themes. These cause the package to be quite big. Also, the extra themes in this package are much easier to tweak than the default theme. The reason is that they are not stored in a .dat file but in a directory structure, with plain .pcx, .wav and .xm files.
- More scripts. Any contributed script will be put there.
- Documentation in many formats, from raw plain text to HTML i and ready-to-print PDF files.

Basically, if you like U61, do not hesitate to download u61-data. The base u61 package is just for you to know if U61 can run on your computer. If it runs, go ahead and download the rest of the game!

## Download instructions

U61 is freely available on the internet. As it is free software, you might also find it on a CD-Rom. If you do not have U61 and want to get it, try the following URLs:

- "http://www.ufoot.org"
- "http://sourceforge.net/projects/u61"

You may also get "u61" and "u61-dat" from CVS, using the following commands:

    cvs -d:pserver:anonymous@cvs.u61.sourceforge.net:/cvsroot/u61 login
    cvs -z3 -d:pserver:anonymous@cvs.u61.sourceforge.net:/cvsroot/u61 co u61
    cvs -z3 -d:pserver:anonymous@cvs.u61.sourceforge.net:/cvsroot/u61 co u61-data

When you are prompted with a password, just press "ENTER".

## Required tools and libraries

### Libraries

These libraries are required only if you want to compile and install U61 from the source. The Linux and Windows binaries are statically linked against all these libs so that you don't need to install them to run the game.

- zlib 1.1.3 : http://www.info-zip.org/pub/infozip/zlib/
- Hermes 1.3.1 : http://clanlib.org/
- Lua 3.2 : http://www.tecgraf.puc-rio.br/
- libMikMod 3.1.8 : http://mikmod.darkorb.net/
- ClanLib 0.5 : http://clanlib.org/

### Tools

These tools are required if you try to compile U61, if you got a binary distribution, you do not need them.

- C++ compiler : gcc under Linux, Visual C++ 6.0 under Windows.
- Python 1.5.2 : needed to build the themes and compile the docs.
- LaTeX : needed to compile the docs.
- PDFLaTeX : needed to compile the docs.
- dvips : needed to compile the docs.

## Source install under Linux

In theory, the best way to install U61 is to install it from the sources. However, on my machine, it can take me up to 3 hours to compile all the required libs and then the game. And keep in mind that I'm quite used to compiling U61 8-) So it might be a wise choice to download the static binary, which is about 1Mb bigger, but will probably save you more than 2 hours, unless you have already a working ClanLib install and a fast CPU.

Here are some reasons you might wish to install U61 from the source:

- You want to use a specific ClanLib target, such as ggi for instance, since the static binary uses the default X11 target.
- You want to install U61 in another location that /usr/local, because you are not root on your machine or just don't like /usr/local.
- You don't have a Pentium or for some strange reason the static binary segfaults on your machine.
- You never install binaries on your computer. Just like me 8-)

The source files should be named:

- u61-?.?.?.tar.gz
- u61-data-?.?.?.tar.gz

U61 uses GNU autoconf. The install scripts I've prepared aren't perfect and do not check everything, but most of the problems should be detected. Let's say for instance that you are installing version 0.3.0. Once you got u61-0.3.0.tar.gz, type:

    gunzip u61-0.3.0.tar.gz
    tar xf u61-0.3.0.tar
    cd u61-0.3.0
    ./configure
    make

Now log as root and type:

    make install
    exit
    u61

And if everything is all right, you should see the game running...

The installation of "u61-data" is pretty much the same, but keep in mind that:

- It makes no sense to install "u61-data" without "u61".
- "u61" and "u61-data" should have the same version. For instance u61-data-0.3.0.tar.gz is supposed to be installed with u61-0.3.0.tar.gz.
- If you change the default install directory, by using "configure --prefix=/usr/mydir/" for instance then you must use the same option with "u61" and "u61-data".

## Binary install under Linux

Since release 0.4.1, a static binary for Linux is available. Since the executable is statically linked against ClanLib and every library including the GNU libc, it should run on any Linux box which has an up to date kernel and X-Server running. In fact, if this binary does not work, installing from the source will probably not help much, but at least it might give you an idea of what's going wrong.

Note that the files are named "...-i386-binary.tar.gz" but there might be some problems running them on a plain 80386 computer. In fact, they are "i386" files as opposed to SPARC or ALPHA files, but they probably require a Pentium to run. If you want to run the game on a true 386, you can still try and compile the source but the game will be very very sloooow.

The static binary files should be named:

- u61-?.?.?-linux-i386-binary.tar.gz
- u61-data-?.?.?-linux-i386-binary.tar.gz

Let's imagine you are installing version 0.4.1. Once you have downloaded the files, type:

    gunzip u61-0.4.1-linux-i386-binary.tar.gz

Now log as root and type

    tar xfP u61-0.4.1-linux-i386-binary.tar

Now log as a single user under X11 and type "u61" in an X-Term, and the game should run.

Note the "P" option in the tar command line, which tells tar to preserve full path names. This means the files will be installed directly in /usr/local, that's why you need to log as root. More precisely, files are installed in the following directories:

- /usr/local/bin : binary files
- /usr/local/share/u61 : theme and script files
- /usr/local/man/man6 : documentation as a man page
- /usr/local/doc/u61 : documentation in various formats
- /usr/local/share/pixmaps : icon for Gnome, KDE, WMaker...

## Source install under Windows

If you want to install U61 form the source under Windows, you'll need Microsoft Visual C++ 6 and a fair amount of free time 8-) The MSVC workspace is included in the Linux source tarball, so this is what you need to do:

- Get the Linux source tarball, and unzip/untar it.
- Get a working ClanLib developper install. Try to compile the ClanLib examples first.
- Tweak the U61 project file so that it matches your personnal install. You'll probably have to change some include and/or library directories.
- Pray that MSVC does not segfault when compiling 8-)
- Create a directory structure which matches the one I use in the binary releases. The most important point is that u61.exe must be able to find the theme and script files.

If this succeeds, you'll probably end up with exactly the same content as the default binary release, so at this time you might wonder: "why the hell did I spent a whole afternoon doing this?" 8-}

BTW, there's no easy way - at least I do not provide it - to compile the datafiles under Windows. What I personnally do when I release windows binaries is that I import the compiled datafiles from my Linux environment. As I almost never run Microsoft Windows, and since this poor system does not have a decent batch support, I'm not ready to implement and maintain such a fonctionnality.

## Binary install under Windows

All you have to do is unzip the file in a directory, for instance "C:\Program Files\".

WinZip - or whatever unzipper you use - should create a "U61" subfolder, which contains everything, including the "U61.EXE" file you have to launch to play the game. If you want to install "u61-data" - I recommend you do it - you'll have to install it in the same directory. That's to say that any file which is in both "u61" and "u61-data" - for example "COPYING.TXT" - must be overwritten when "u61-data" is installed.
