In the default ebuild, Fargoal crashes immediately with a segmentation fault for any non-root user. The problem is the /usr/share/games/fargoal/ subdirectories and files only allow access to the games user, not the games group: /usr/share/games/fargoal/data: total 4 -rw-r----- 1 games games 3312 Mar 28 15:40 sof.cfg /usr/share/games/fargoal/gfx: total 1668 -rw-r----- 1 games games 38462 Mar 28 15:40 black.bmp -rw-r----- 1 games games 9142 Mar 28 15:40 chars.bmp -rw-r----- 1 games games 36342 Mar 28 15:40 chars_ep.bmp ... /usr/share/games/fargoal/sfx: total 860 -rw-r----- 1 games games 10520 Mar 28 15:40 attack.wav -rw-r----- 1 games games 45252 Mar 28 15:40 beacon.wav -rw-r----- 1 games games 12172 Mar 28 15:40 boom.wav Reproducible: Always Steps to Reproduce: 1. emerge sync 2. emerge fargoal 3. run fargoal as a normal user Actual Results: Segmentation fault Expected Results: Open screen and play game.

Hmm, tried a couple more times and I got dan@fluff dan $ fargoal Shutting down Allegro due to signal #11 Segmentation fault I noticed someone else had the same problem with atanks: http://forums.gentoo.org/viewtopic.php?t=133296 I have allegro-4.0.3 installed on a 2.6.5-rc2 vanilla kernel running ALSA on my intel_8x0 audio. My user is a member of the audio group. Possibly some conflict with artsd? Hmm. Well, good news of a kind -- root is now also segfaulting when I try to start fargoal. This did work, once...
All right. Stopped artsd (through Settings -> Sound & Multimedia -> Sound System -> Disable sound system) and I was able to start the game as a regular user (yay) but the game segfaulted on exit. Note that suspending the sound system through the aRTS control tool didn't do the trick. One step at a time...
http://arts-project.org/doc/handbook/faq.html#id2804552 has some interesting information in "How can I run old, non-aRts applications?" and suggests using the artsdsp wrapper to run the program, e.g. artsdsp fargoal However, that also results in a segmentation fault. A further suggestion in that FAQ is to suspend arts using "artsshell suspend" and then run the application: artsshell suspend && fargoal However, just as when I suspend aRtsd manually, fargoal seg faults. So, the only thing I can do seems to be to alias fargoal so that aRtsd is stopped before running fargoal, then started again after fargoal ends: alias fargoal='artsshell terminate && fargoal && artsd' Of course, fargoal still seg faults when I exit the game, but at least I can play it. Suggestion? Perhaps the ebuilds for fargoal and other games that don't play well with aRts could include a simple wrapper that checks the status of aRts and then performs the tasks in my alias. It seems really heavy-handed, but it's a simplistic approach that will get the job done. The right thing to do would be to make all these games play nicely with aRts and other sound daemons; however, that's a fair bit of coding. Fargoal doesn't even seem to have any configurable options, so you would have to add an extension just so you could choose a different sound daemon.
Please post the output of the command `id`.

Hmm. The version of Allegro installed with 2004.0 is positively ancient (4.0.3); here's a link to the changelog for 4.1.x: http://alleg.sourceforge.net/onlinedocs/en/changes.html Most interesting (in the 4.1.13 release): * Improvements to the ALSA 0.9/1.0 and aRTs sound drivers. In the 4.1.0 release: * Peter Wang fixed the detection of ESD and aRts on Unix systems. I'll try unmasking and emerging 4.1.12 (latest available in Gentoo packages) to see if that resolves the problem.
Ahh... allegro 4.1.12 makes things better. Now if I manually suspend aRTsd (using `artsshell suspend`) or wait for it to auto-suspend, fargoal will start up happily. However, if aRTsd is not suspended, fargoal will segfault with the following error: bash-2.05b$ fargoal fargoal: Symbol `key' has different size in shared object, consider re-linking ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: Device or resource busy Shutting down Allegro due to signal #11 Segmentation fault
Changed summary to more accurately represent the problem
how's it like allegro-4.1.15?
Need feedback...
No feedback.
It likes allegro 4.1.15 a lot. Works perfectly, in fact. So do close this once 4.1.15 goes into stable?
Since I believe it works with the only two versions of allegro in portage I'll close it now. We can reopen it later if there are more problems.
The error <<has different size in shared object, consider re-linking>> can be fixed by remergint the package owning the file. See bug 338347
