No, epeg is dead, even more dead than imlib2. I think the current replacement library from the E project for both these libraries is the evas library.

The SDL egg is rather dusty and there might be such dark corners. I will file this as a bug and will have a look at it during the holidays. Great, much appreciated! If you find the time you could build a chicken with debugging information (add DEBUGBUILD=1 to the make call) and show be the backtrace of that. This might be of more help than the standard backtrace. Fine, i'll try to do that during the holidays! The problem seems to be triggered by the use of text-extents. I uploaded a newer testcase to the bug report that makes heavier use of extents and also crashes almost immediately on my machine. I also added a backtraces from a CHICKEN built with DEBUGBUILD=1.

I still don't see the problem, but I've found a smaller testcase that reliably crashes (for me, at least): (use cairo) (define t1 (make-cairo-text-extents-type)) (display t1) (cairo-text-extents-x-bearing-set! t1 1) (display t1) I also discovered a bug in the record printer for the extents types, patch attached.

Re: [Chicken-users] [Patch] Cairo's ffi may be wrong...
Hi Christian, On Sat, Oct 08, 2011 at 11:15:19PM +0200, Christian Kellermann wrote: I have toyed around with the cairo egg and experimented with text flow given a box with a specified size. In the result of this I have been calling the cairo-text-extents procedures a lot which resulted in either segmentation faults or out of memory panics. This procedure creates a u8-vector that it passes to the cairo C function which treats it as a struct and fills it's slots. The casting is done with a typed c-pointer. Jim suggested on #chicken that cairo's use of c-pointers pointing to scheme objects may be the culprit here as we don't point to the data itself but to the non immediate scheme object as a whole. So the attached patch uses scheme pointers instead of the c-pointers for these structures which makes additional casting necessary for the accessors. Maybe adding a typed variant of scheme-pointer would make sense? It also uses blobs for the storage space instead of u8-vectors since the manual (and Jim) warns against its use wiht a scheme-pointer. (As much as I understood it, I may be completely off track as well). Thanks to Jim for the suggestions, errors in the patch are all mine. I have posted this to chicken-users, because I would like to know whether someone else besides me uses this egg and has seen similar strange things *and* is willing to test this patch before I am going to apply it to trunk (if it is correct at all!). So please speak up if you do use cairo and let me hear your experiences with it. I'm planning to use cairo for a small visualization tool, but so far I've not gone beyond some dummy test. I have not seen any problems so far, but also didn't use cairo-text-extents yet. In any case I can confirm your patch did not break my dummy program!

Could this be used to interact with Qt QML and Quick? I haven't used these, but if QML is ECMA-Script-compliant, I see no reason why it shouldn't work. I would be very interested in the results, in case you are going to try it out! Ok, great! I unfortunately will not have time soon, but if I do I'll report the results..

[Chicken-users] 3viewer crash
Dear List, I just gave the 3viewer egg a try, but running the example resulted in a core dump (both compiled and interpreted).

The attached little patch fixes this for me (debian testing, libsdl-dev 1.2.14-6). Thanks, Markus. I have added the change and tagged a new version (0.1.5).
