Gentoo install

Installation

This is for version 0.76b1.

An overlay to use with layman is provided. If gentoo overlays and/or layman are new to you, read about them, as they are an essential part of gentoo.

This example assumes you never used layman before. If it's not your first time, you hopefully know what to do.

### install layman (with git support)
echo "app-portage/layman git" >> /etc/portage/package.use
emerge layman
echo "source /usr/portage/local/layman/make.conf" >> /etc/make.conf

### add spring overlay to layman
layman -f -a Spring -o \
'http://www.springlobby.info/overlay/?p=springlobby.git;a=blob_plain;f=overlays.xml;hb=HEAD'

### allow installation of unstable versions
echo "games-strategy/spring ~x86" >> /etc/portage/package.keywords
echo "games-util/springlobby ~x86" >> /etc/portage/package.keywords

### install game and lobby
emerge spring springlobby

Layman makes upgrading really easy too:

### update the repository and check for new versions
layman -S

### upgrade existing installations
emerge -u spring springlobby

Your paths are: Spring executable in /usr/games/bin/spring and read-only data in /usr/share/games/spring.

Finalizing installation

You should have Spring installed by now; if not, please see the SetupGuide.

Maps & Mods

Since Spring is only an engine, you need to download games for it, and the maps that go with those games.

SpringLobby will automatically do this for you when you attempt to join a game with a map or mod that you do not currently have, using an integrated downloader.

If you want to download it manually or browse existing maps, there are several easy to use websites:

• SpringFiles
• Spring-Portal
• Darkstars

Pick any of those sites, download a map or mod, and then double click it. This will move it to your Spring folder, using the spring map/mod installer program. If you wish to move maps/mods by hand, they are located under ~/.spring/maps/ or ~/.spring/mods/ (if the folder does not exist - create it). Do not unpack the file in any way though, just download and save it. Reload your maps/mods in SpringLobby, (Tools - Reload maps/mods) and they will be ready to use.

These sites also may provide other neat things like Lua widgets, epic replays, AI bots (for playing offline or to team up on with a friend). Generally the installation requires you to download the file and place it in the appropriate folder in your ~/.spring directory. (you may have to create the folder)

Hint: If you know the name of the map you want, there is a Search function provided in those websites. Just write a part of the name, like one word, and you will easily find the map you were looking for.

Linux specific Troubleshooting

Ingame

Slow Mouse

Run:

echo '# Slow fullscreen cursor fix for Spring' >> ~/.xsessionrc
echo 'SDL_MOUSE_RELATIVE=0' >> ~/.xsessionrc
echo 'export SDL_MOUSE_RELATIVE' >> ~/.xsessionrc

And log out and log in again.

The mouse should now be as fast as in windowed mode.

Rotating Buildings

You can rotate a building before you give the build order, but the keys that do this do not work in Linux by default for some users. Issue the following commands in the beginning of the game:

/bind keycodex buildfacing inc
/bind keycodey buildfacing dec

Keycodex and keycodey above are just placeholders. What you want to write depends on which key you want to use. To see what keycodes any keys have, do:

/keydebug yes

And then hit the keys you want to use, and spring prints the keycodes in the message buffer.

If you want to save these keys you have to edit the uikeys.txt.

Problems with Audio

The engine needs at least OpenAL Soft 1.6 for its sound. If you still have the old openal-0.0.8 installed, you should update it.

Additionally, pulseaudio causes lots of issues, so try to disable it for spring if you have sound problems.

Desync in game

Spring only send the commands and not the result over the network, so it needs to run all math in a repeatable manner, so all other clients in a multiplayer match get the same results. So some CPU specific features have to enabled/disabled. If you desync, you either have a CPU that is not SSE1 capable, or you set the wrong -march/-mtune compiler flags. If you compile Spring via CMake, remove CMakeCache.txt, and leave the march flag at the default.
