Port liblrdf to raptor2

[ssuominengentoo]

Both ArchLinux and Gentoo come with raptor2 patched liblrdf, but ArchLinux is missing pkgconfig patch required by reverse dependencies to get -I include flags to find raptor.h as well as -lraptor2 for static linking.

Please see both -raptor2 and -raptor2-pkgconfig patches from here:

That's great! I'll take a look at it and try to merge it in. Care to make a pull request?

And to provide migration plan for distribution maintainers, in addition to patching liblrdf, these needed fixing too:

http://qa-reports.gentoo.org/output/genrdeps/rindex/media-libs/liblrdf

Aqualung:

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-sound/aqualung/files/aqualung-0.9_beta11-use_lrdf_cflags.patch?revision=1.1&view=markup

Ardour:

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-sound/ardour/files/ardour-2.8.11-raptor2.patch?revision=1.1&view=markup

Galan:

This package is "dead" at upstream so I was lazy and simply appended pkg-confg --cflags lrdf to CPPFLAGS instead of writing a proper patch for it.

Hydrogen:

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-sound/hydrogen/files/hydrogen-0.9.5-use_lrdf_pkgconfig.patch?revision=1.1&view=markup

(But something is wrong with the build system, as the flags get lost during half of the build. As in, the patch is a bit incomplete. I used this patch and the same workaround as Galan above.)

Jack-Rack:

Same as Galan, simply passed pkg-config --clags lrdf to CPPFLAGS.

Rosegarden:

Worked out of box after applying the 2 patches to lrdf.

Sonic Visualiser:

Applied workaround from here http://code.soundsoftware.ac.uk/issues/136
It doesn't need to check for presense of raptor, because it simply gains it from liblrdf
after the 2 patches are applied.

TerminatorX:

Seems to just work...

Overall, liblrdf reverse dependency upstream maintainers need to use more pkg-config, and assume locations less.

[taybin]

Used the basic raptor2 patch and build system modifications.

I also removed the private MD5 implementation and replaced it with MD5() from openssl.

I'm going to wait a little bit for comments, and then tag 0.5.0.

[amitkulz]

taybin, will you please tag 0.5.0? we can use an update.

ssuominengentoo, thanks a bunch for hunting it down. don't you need liblrdf for gstreamer-plugins-bad too?

thanks a bunch for working on this guys!

[ssuominengentoo]

amitkulz, most likely but it seems Gentoo Linux Gstreamer maintainers haven't packaged this plug-in from the -bad bundle, so I've missed it.

taybin, yes please tag 0.5.0 after committing fix for http://github.com/swh/LRDF/issues/3

[taybin]

Fixed issue #3. I'm just cleaning up an issue with make distcheck and then I hope to tag.

[ssuominengentoo]

I made a git snapshot and shipped it in Gentoo's Portage but I stumbled over:

#5
#6

When packaging it.

In any case, it should now get a bit more wider testing...

[amitkulz]

good thing you found those issues before the tag :-)

[taybin]

Fixed those two issues. Please retest and then I will finally tag.

[ssuominengentoo]

The current git worked for me out of box now. Thanks

Time to close this...
