Bug 56933 – supertux-0.1.1-r1: "Error: Can't covert to display format"

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Carsten Milkau 2004-07-13 10:57:53 UTC]

$ supertux
Datadir: /usr/share/games/supertux
Warning: No joysticks are available.

Error: Can't covert to display format
/usr/share/games/supertux/images/status/letters-black.png

Abgebrochen

This error message only appears when running supertux as a non-privileged user, it's probably some wrong permissions.  It is a quite strange error message, so I do not know how to recover from it.  I post this to gentoo because the message appeared after the update of various gentoo packages which did NOT include the supertux package.  I think this might be caused by a dependency or ebuild error.

Reproducible: Always
Steps to Reproduce:
1. emerge supertux-0.1.1-r1
2. run supertux as non-privileged user
3.

Actual Results:  
Error message as mentioned above, program abort. 

Expected Results:  
program startup

What's the ouput of the groups command for the user?

[Comment 2 Carsten Milkau 2004-07-14 06:37:38 UTC]

$ groups
tty wheel floppy audio cdrom games cdrw users parport vmware-user fetch

[Comment 3 Mr. Bones. (RETIRED) 2004-07-17 03:18:45 UTC]

Remerge libsdl, run revdep-rebuild and remerge supertux and see if that makes
a difference.  Works fine here.

[Comment 4 Mr. Bones. (RETIRED) 2004-07-25 23:43:13 UTC]

Reopen with the results of trying that please.

[Comment 5 Carsten Milkau 2004-07-26 01:01:52 UTC]

Rebuild of broken dependencies solved the problem for me.  I am sorry but I do not have the output of revdep-rebuild on hand.  I believe to remember that libSDL and friends were involved.

[Comment 6 Mr. Bones. (RETIRED) 2004-07-26 01:16:59 UTC]

Ok. sounds fixed to me.

[Comment 7 Carsten Milkau 2004-08-29 13:54:51 UTC]

The problem appears again in supertux-0.1.2. Revdep-rebuild does not find broken binaries, nor does remerge of supertux help.

[Comment 8 Mr. Bones. (RETIRED) 2004-08-29 18:13:23 UTC]

rebuild all the listed deps for supertux and try merging it again.

[Comment 9 Carsten Milkau 2004-08-30 04:23:39 UTC]

I rebuilt media-libs/sdl-image-1.2.2, which made the error disappear. However, I think it is not a good thing that this necessity was not discovered by the portage tools.
Nevertheless this "works for me" now. 

[Comment 10 Mr. Bones. (RETIRED) 2004-08-30 11:54:14 UTC]

I don't know why you have this failure.  I have never seen it.

[Comment 11 Pekka Paalanen 2008-08-02 11:07:18 UTC]

I've hit the same problem as in the original report, with supertux 0.1.3.
I've tried re-emerging libsdl, sdl-image, sdl-mixer, libXt, and supertux itself, but the problem persists.

'sudo /usr/games/bin/supertux' exhibits the problem, but 'sudo su -' and then '/usr/games/bin/supertux' does not, so it's probably something in the environment. Very weird.

The error message can be found in this source file:

Please post your emerge --info and check if you have the png use flag enabled
