ppsspp-libretro-1.0_pre20180317-r1 build failure

[ghost]

Hello,
trying to build this package gives me

git update-ref --no-deref refs/git-r3/games-emulation/ppsspp-libretro/0/__main__ dbbe316c5617a4608dcab4a568fb090b207aa21a
fatal: update_ref failed for ref 'refs/git-r3/games-emulation/ppsspp-libretro/0/__main__': cannot update ref 'refs/git-r3/games-emulation/ppsspp-libretro/0/__main__': trying to write ref 'refs/git-r3/games-emulation/ppsspp-libretro/0/__main__' with nonexistent object dbbe316c5617a4608dcab4a568fb090b207aa21a

I have no idea of what it means.

ppsspp-libretro seems to have been rebased a few days ago. That means that the src users downloaded before that time are incompatible with current upstream. Please delete ${DISTDIR}/git3-src as root, normally like this rm -rf /usr/portage/distfiles/git3-src.

I bumped the ebuild just in case there are still missing refs at the old commit.

Now it fetches, but compilation fails with

Yeah, a fix is already commited to original upstream but didn't land on libretro yet. I hope I chose a commit that works for now.

New ebuild didn't change a thing. I deleted ${DISTDIR}/git3-src too, to be sure.

[stefan-gr]

This one includes the fix I was talking about.

Perhaps, you need to package v1.5.4 from https://github.com/libretro/ppsspp/releases

[stefan-gr]

I took a peek into the Makefile and noticed that the sed lines aren't needed anymore and had the potential to break building. I think that was responsible for this.

The releases are from upstream ppsspp and don't include libretro.

games-emulation/ppsspp-libretro-1.0_pre20180328 can be built, but there should be protections against git repository rebase which happens often.

[stefan-gr]

In the past I caught these things almost as soon as they happened because I used to sync everyday and used smart-live-rebuild to be up-to-date upstream. But it's true that it is bothersome that upstream changes their underwear so often.

The most reliable way is to host the non-9999 sources somewhere save and fetch them from there.

Perhaps we could use github in some way to deliver them, I think I can upload binary files when making a tag release and edit it according to version bumps. Well, that will have to wait until I have gentoo again so that I can get all needed tarballs to calculate if github would be able to host them.
