/usr/bin/debugedit: /var/tmp/portage/dev-lang/python-2.7.18-r6/image/usr/lib64/python2.7/lib-dynload/_struct.so: DWARF version 5 unhandled
/usr/bin/debugedit: /var/tmp/portage/dev-lang/python-2.7.18-r6/image/usr/bin/python2.7: Unknown debugging section .debug_loclists
/usr/bin/debugedit: /var/tmp/portage/dev-lang/python-2.7.18-r6/image/usr/bin/python2.7: Unknown debugging section .debug_rnglists

I guess we'll have to wait for upstream to merge this.  I can do a backport then if necessary, though I suppose it'd be better to wait for a release.

debugedit-0.2.ebuild

Trivial ebuild for nascent split debugedit project

background:

Getting recent rpm to build (with or without debugedit) seemed infuriatingly difficult and confusing.  I'm sure I was just doing something dumb and it's not so bad, but I tried to figure it out for hours without success.  Scouring the 'net for hints I stumbled across these:

http://lists.rpm.org/pipermail/rpm-ecosystem/2021-February/thread.html#734
https://sourceware.org/bugzilla/show_bug.cgi?id=27351

So the whole stupid problem is actually in the process of being properly solved and we can trivially leverage this.  Attached is a no-phase-function ebuild for this project.

Not sure about the popt dep, is that about appeasing rpm or a real thing?

Anyhow, bazinga!  Enjoy your debug symbols again ... or, quite plausibly, enjoy debugging why they don't actually work despite this ebuild :)

Looks like standalone debugedit 5.0 has been tagged as of a few days ago: https://sourceware.org/git/?p=debugedit.git;a=commit;h=1745c1e80772a6c2cb53db2507ce1f07d49691e3

Please don't attach files unless you're going to attach signed-off git patches.  There's a big warning above the attachment form about that.

Ah, I meant the versioning problem, but it's resolved ;)
