I prepared libjpeg-turbo package in my home project (home:prusnak / libjpeg-turbo) some time ago. Upstream promised to deliver 1.0.2 soon which will be compatible with both v6 and v8 API, but the project page still has only 1.0.1. If they will indeed release such version, it could help us a lot and save us headache ...

Do you mean to provide both v6 and v8 from jpeg-turbo? The problem is http://libjpeg-turbo.svn.sourceforge.net/viewvc/libjpeg-turbo/trunk/README-turbo.txt?revision=305&view=markup says the v7/v8 compatibility will not be complete (and since everybody is starting to use libjpeg-turbo I expect it to never be). IMHO if someone creates a binary linked to libjpeg.so.8 we owe him to have a 100% compatible library. The app will not have the speed boost, but that's something the binary creator should accept if he decides to not link to libjpeg.so.6. So libjpeg.so.8 should be provided from IJG's source. It could be *also* provided from jpeg-turbo so the user can change it if he decides to do so, but that would be unnecessary courtesy. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

Hi list,

I would like to hear your opinion about future jpeg packaging. I am asked to switch back to jpeg6 in Factory.

Nowadays we have following packages in graphics project: * libjpeg6 (contains only library) * libjpeg7 (contains only library) * jpeg (contains doc files and bin tools)    -> libjpeg8 (contains library)    -> libjpeg-devel (contains *.h and *.so)

I should do full-fledged jpeg 6 package as jpeg (8) is and we should have it in parallel if I understend correctly (not sure about jpeg 7 package).

jpeg 7 only existed for 6 months, I don't think there is any use for it. But we are already testing this... 11.3 hasn't a libjpeg7 packages, was any bug report created asking for it?

...

I would appreciate any advice, here is a first thought proposal:

* jpeg6 (contains doc files and bin tools)       provides: jpeg, obsoletes: jpeg, conflicts: jpeg8  -> libjpeg6 (contains library)  -> libjpeg6-devel (contains development files)          provides: jpeg-devel, obsoletes: jpeg-devel,          conflicts: jpeg8-devel

* jpeg8 (contains doc files and bin tools)       conflicts: jpeg6   -> libjpeg8 (contains library)   -> libjpeg8-devel (contains development files)          conflicts: jpeg6-devel

Requires should stay same modulo major version.

jpeg6 should be compiled from libjpeg-turbo. But it seems OK to me.

And in case 11.4 finally includes libjpeg-turbo 1.0.1 instead of 1.0.2, please apply http://libjpeg-turbo.svn.sourceforge.net/viewvc/libjpeg-turbo?view=revision&revision=290 to avoid problems when both v6 and v8 libraries are in the same process image. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

Now that's a mean problem. 11.3 repo has a "real" libjpeg-devel, so the provides of libjpeg8-devel aren't looked at. I'm not sure how to fix this problem - but I know changing build requires is wrong ;( Greetings, Stephan -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

I disabled and wiped libjpeg8 for 11.3 now and adapted the project config for the other distros. This works for graphics, but you won't get an updated libjpeg8 lib for 11.3 either ;( Greetings, Stephan -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

Do you want build against libjpeg-turbo or libjpeg8? Petr

The blender people are very interested to see if it works with libjpeg-turbo and because it builds and works fine with libjpeg6, I assume it won't have a problem with libjpeg-turbo. I'm going to put libjpeg-turbo in my home:plater:blender project and give it a try, any known pitfalls?
