Description: A screensaver for use with Linux and UNIX, that pays homage to the classic space trading game of Elite. Eleet displays textured rotating OpenGL models of various spaceships, based on on those found in Elite.
A random ship is chosen from a pool of 53 models and rotated against a starfield background, whilst the name of the ship orbits around it. Ships with exhausts will also emit thrust particles.Last changelog:
V0.3.3: 2012-06-01 - Fixed: Build time fixes for newer distros which use --as-needed as a default GCC option
V0.3.2: 2011-03-14 - Fixed: Improved building scripts for newer distros - Fixed: Now doesn't display cursor. Thanks to "druciferre"
V0.3.1: 2010-06-27 - Fixed: Minor change to the build scripts to fix compilation on distros using the new DSO changes to ld (eg Fedora 13).
V0.3: 2009-10-02 - Added: Smoothed starfield points for OpenGL/Hardware implementations which support it. - Added: Thrust particle emission from exhausts. - Added: Exhausts do not respond to lighting, giving the effect of glowing when not lit. - Added: Support for the orbiting ship name on OpenGL implementations that do not support 'Non-Power-Of-Two' textures. - Added: The orbiting ship name is now randomly coloured. - Added: PNG texture support, saving approximately 7.5MB of space. - Added: Command line parameters: starnum, thustnum, switch - Added: Setup options for XScreensaver - Added: [Installer] Also look in /usr/local/kde4/bin and /usr/kde4/bin for kde4-config - Fixed: The orbiting ship name transparency is now also applied to the stars - Fixed: Don't show in KDE 'Lost & Found' menu on some distros if both the KDE and Gnome versions are installed. - Fixed: [Installer] Installing for KDE 4 on BSD should be fixed. Sed on BSD does not support the newline character in substitutions. - Misc: Some texture improvements to Remlock - Misc: Reduced clipping distance. - Misc: Starfield optimisations which should improve performance, especially on slower systems.
V0.2: 2009-09-06 - Added: Support for KDE screensaver - Added: Support for XScreensaver - Added: Window ID can be passed with -window-id parameter - Added: Rotating starfield effect shown behind the models - Added: Basic lighting - Added: Use DisplayLists to 'precompile' OpenGL which should improve performance, particularly on low end hardware - Fixed: Random ints were only generated up to (upperbound - 2). Worm and Zarch models were never shown as a consequence. - Fixed: On slow systems, draw events could fill up the queue faster than they were processed leading to unresponsive keyboard input or termination of Eleet. - Fixed: Explicitly free graphics memory for dynamically generated textures on exit - Misc: Use gluCheckExtension() instead of parsing glGetString(GL_EXTENSIONS); - Misc: Major code restructuring - Misc: Primitive optimisations to Asteroid, Cargo and Thargon - Misc: Texture improvement to docking bay doors on Dodec - Misc: Removed random wireframe mode (will likely be an option in future) - Misc: Removed orbiting text for implementations of OpenGL that don't have NPOT texture support, in preparation for future work.
I installed or updated as appropriate the following packages:
alsa-lib-devel autoconf automake libdrm-devel libX11-devel libXau-devel
libxcb-devel libXdamage-devel libXext-devel libXfixes-devel
libXrandr-devel libXrender-devel libXxf86vm-devel mesa-dri-drivers
mesa-libGL mesa-libGL-devel mesa-libGLU mesa-libGLU-devel SDL-devel
SDL_image SDL_image-devel SDL_ttf SDL_ttf-devel xorg-x11-proto-devel
After configuring, make dies with:
gcc -g -O2 -lSDL -lpthread -lGL -lm -o eleet eleet.o eleet_timers.o eleet_textures.o eleet_fonts.o eleet_random.o models/LOTSOFMODELS -lX11 -lSDL_image -lSDL_ttf
eleet.o: In function `preCacheScene':
/tmp/eleet/eleet-0.3.1/src/eleet.c:300: undefined reference to `gluCheckExtension'
eleet.o: In function `initOpenGL':
/tmp/eleet/eleet-0.3.1/src/eleet.c:366: undefined reference to `gluPerspective'
collect2: ld returned 1 exit status
Those functions are defined in GL/glu.h. eleet.c includes eleet.h, which (conditionally, but in this case positively) includes GL/glu.h. As far as i can tell, my include path is set up properly.
Any thoughts?
This is due to some changes in F14, I'll post an updated version at some point.
You should be able to work around it.
Instead of just using make to compile it, try:
make LDFLAGS="-lGLU"
Let me know how that goes.
That works, thanks!
So the problem is with the linker finding the libraries, not the compiler finding the includes, as i'd been assuming. I suppose the "ld returned 1 exit status" should have been a clue.
Nice add to the screensavers - thank you !
Working fine with the Kubuntu 9.04 / KDE 4.2.4.
Small flaw (?)- the ship models are there but not the ship name.
(?) - i don't mind. Maybe the nex version has a setting to enable/disable the ship name.
Again - Thank You !
Thanks. :-)
There's a section in the README about it that explains why you won't see the ship names on some systems. It's essentially that your OpenGL implementation doesn't support NPOT textures and I haven't written code yet to emulate it (but plan to). The glxinfo command should tell you your OpenGL version and most likely it's less than 2.1.
