Bug 310741 – media-video/vdr-1.6.0_p2 does not compile with <media-libs/jpeg-8

• Product: Gentoo Linux
• Status: VERIFIED FIXED

[Description Stefan Bauer 2010-03-22 16:19:30 UTC]

Stable vdr-1.6.0_p2 depends only on media-libs/jpeg, but fails with stable jpeg-6b-r9 and testing jpeg-7-r1. I suggest vdr should depend on >=media-libs/jpeg-8.



Reproducible: Always

Steps to Reproduce:
1. Ensure only jpeg-6b-r9 or jpeg-7-r1is/will be installed (i.e. mask jpeg-8)
2. emerge vdr


Actual Results:  
Build fails (see coming build.log).

Expected Results:  
VDR should build.

why would you mask jpeg-8? 

the old jpeg's are for binary-only applications, and only for them, no installed headers at all

that said, i've committed the change to all vdr ebuilds

Created attachment 224707 [details]
build.log of vdr with jpeg-6b-r9 installed

An interesting thing:

$ equery f jpeg

No headers installed at all!?

I'm currently digging down another bug in a package depending on jpeg (https://sourceforge.net/tracker/?func=detail&aid=2974620&group_id=160063&atid=814342). I wanted to check for regressions in jpeg.

Thanks for explaining this.

Thank you.

There was a regression in jpeg-8, please upgrade to jpeg-8a.

Also don't forget to run,

revdep-rebuild --library libjpeg.so.62
revdep-rebuild --library libjpeg.so.7

To sanitize the system (a.k.a. relink everything against libjpeg.so.8 that is still linked to old jpeg). Otherwise all debugging data is more than unrealiable :)

I just looked at the bug again, grep the sources for cinfo.raw_data_out or cinfo.raw_data_in. If you find those, you likely need similar patch to one applied in portage for media-video/mjpegtools

/usr/portage/media-video/mjpegtools/files/mjpegtools-1.9.0-jpeg-7.patch
