1 Requirements
1.1 What are the requirements to run the game?
 Linux Kernel 2.2.x or later
Glibc 2.1.x or later
XFree86 version 4.3.x or later
Pentium 1.4GHz or better
540 MB RAM
3D Graphics Card with at least 64 MB of memory, OpenGL 1.3, 4 Texture Units, fragment and vertex extentions
OSS or ALSA compatible sound card
DVD Drive
1.1GB Disc Space

2 Installation
2.1 When I try to mount /mnt/cdrom or cd /mnt/cdrom I am told `no such file or directory`
 Some distributions have now changed the default location for the CD Rom

Try using /media/cdrom
If that does not work, and you have a CD or DVD burner, try using /media/cdrecorder

More recently some distributions will have the disc name in /media. Try looking in /media for a directory whose name matches the name of the game, and use that.

2.2 When installing I get a message like: tail: cannot open `+2` for reading:
 This is due to changes in some of the unix commandline tools.

On the commandline, simply type the following:

export _POSIX2_VERSION=199209

And then try running the installation again, ensuring you run it from the same commandline as you just typed the above command in.

2.3 Installation fails with a message like: /tmp/.setup12345: No such file or directory
 If you are running a 64 bit system, you need to install the 32 bit compatibility libraries.

2.4 [downloaded version or demo only] After the setup program has verified the data, it then fails to start the graphical installer, with a message like: Extraction Failed
 This is usually because there is not enough room in /tmp which is where the game is extracted to.

To resolve this problem, you should ensure you have enough space in /tmp or use the --target option for the installer, which can be used to give it a new directory to install to. For example

gameinstaller.run --target /path/to/directory

3 Updates
3.1 When running lgp_update I get a message like: Searching for installed products... tail: cannot open `+2` for reading:
 This is due to changes in some of the unix commandline tools.

On the commandline, simply type the following:

export _POSIX2_VERSION=199209

And then try running lgp_update again, ensuring you run it from the same commandline as you just typed the above command in.

4 Demo
4.1 I have downloaded the demo, but when I double-click on the icon, it does not install, but opens the demo in another application such as a text editor.
 You need to change the permissions of the demo. By default many Linux versions do not allow you to run things you have downloaded.
Usually, this is done in a method that is similar to this (it varies for each linux version).

Simply right-click on the icon, and you will see a manu that includes an option such as `Properties`

Select this option.

You shoudl at this point see a new window with several options. You need to select the option that is about `permissions`.

When you have, you need to set the `execute` or `run` permission to on.

Click OK, or Apply, and then you will be able to double-click on the icon to install the demo.

5 Starting the Game
5.1 How do I start the game?
 To start the game, you may simply select its entry from your command button on your toolbar. It will either be found in the `Games` or the `Other` section.

5.2 When I try and start the game, I get an error about: symbol errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
 This error can be resolved by typing:

export LD_ASSUME_KERNEL=2.2.5

into the commandline before starting the game. Note you must use the same terminal window to start the game as you type this command into.

5.3 When I start the game, I get a message box popup, reporting Exit code: 0x00000021
 There is an issue with the way Linux handles CDRom drives. You can resolve the problem by installing the 1.0.1 patch using lgp_update.

5.4 When I start the game, I still get a message box popup, reporting Exit code: 0x00000021
 This is probably due to a limitation in your graphics card. On the commandline, type the following

echo compatibility_fix_disable_occlusion_query = 1 ; >> ~/.lpg/coldwar/config.txt

6 Sound
6.1 I get no sound, and messages about (snd_ctl_open_noupdate) Invalid CTL hw:0
 This is usually because of the new PulseAudio system that makes sound difficult to use on Linux.

To fix this problem, you need to do one of the following (in order of ease)

run the game using pasuspender

pasuspender gamename

run the game using padsp

padsp gamename

Finally if these fail, or give poor results, you need to install the OSS layer for ALSA and ensure it is loaded into the kernel. This will vary for each Linux distribution, and you should consult your Linux distribution documentation for instructions on how to do this.
