problem with updating librsvg

[esemds]

Hello everybody,
It's almost 2 weeks i am trying to update my gentoo system but some package (librsvg) does not update and does not compile.
Because lots of other packages depend on librsvg, they dont compile and i can not update lot's of my packaes. (I should mention the version in gentoo packages repo is not updated and is a little outdated). I cloned the git repo (version 2.60.0) and even that version did not compile (updated version does compile), i guess there is a bug or something like that.

this is the output of emerge --info '=gnome-base/librsvg-2.60.0::gentoo'

Hello everybody,
It's almost 2 weeks i am trying to update my gentoo system but some package (librsvg) does not update and does not compile.

Then have Portage build librsvg with emerge --oneshot gnome-base/librsvg, wait until it fails, and then post the build log so that we can have a look at it. Use wgetpaste and a pastebin site if it is too large.

OK, this is the output of emerge --oneshot gnome-base/librsvg https://pastebin.com/FCUyr2eB

AND this is the full log (meson log) https://pastebin.com/bwKz7xx6

AND this is the full log (meson log) https://pastebin.com/bwKz7xx6

Do you still have directory /var/tmp/portage/gnome-base/librsvg-2.60.0 from the failed build? If yes, could you post the output of:

Code: Select all

$ cd /var/tmp/portage/gnome-base/librsvg-2.60.0/work/librsvg-2.60.0/meson
$ /usr/bin/python3.13 query-rustc.py /opt/rust-bin-1.92.0/bin/rustc --query=native-static-libs
$ /opt/rust-bin-1.92.0/bin/rustc --print=native-static-libs --crate-type staticlib /dev/null

?

Yes, i have.
the line /usr/bin/python3.13 query-rustc.py /opt/rust-bin-1.92.0/bin/rustc --query=native-static-libs returns:

util dl rt gcc_s pthread m c

and the line /opt/rust-bin-1.92.0/bin/rustc --print=native-static-libs --crate-type staticlib /dev/null returns:

Code: Select all

note: link against the following native artifacts when linking against this static library. The order and any duplication can be significant on some platforms.

note: native-static-libs: -lgcc_s -lutil -lrt -lpthread -lm -ldl -lc

[GDH-gentoo]

OK. The build fails while doing this, so I wanted to narrow down who's responsible for the "RuntimeWarning: Unexpected value in sys.prefix, expected /usr, got /usr/bin" message. Doesn't seem to be the Rust compiler or the build system's query-rustc.py script at first glance.

What's the output of:

Code: Select all

$ python3.13 -c "$(printf 'import sys\nprint(sys.prefix)')"

?

Is it possible to edit that part of the source, kinda comment it out. I mean will it even work temporary till next update?
BTW, thanks for your time man.

[GDH-gentoo]

Well, since we know in this particular case what the output of meson/query-rustc.py is, and the build fails only because running it through Meson's run_command() function (in the environment set up by Portage) also prints that message to standard error, you could try cheating and using /etc/portage/patches to apply this patch (warning: untested), and seeing what happens:

Hello,
I've also encountered this same problem, and have been prevented from updating my system from sometime in early January because of it (package pinning notwithstanding).

What I am trying to do:
sudo emerge --update --newuse --deep --with-bdeps=y @world

Build log: https://paste.gentoo.zip/AMGZ8PIE (not sure why it displays as a binary file...)
Output of `emerge --info '=gnome-base/librsvg-2.60.0::gentoo'`: https://paste.gentoo.zip/NKGOlrNY
Output of `emerge -pqv '=gnome-base/librsvg-2.60.0::gentoo'`: https://paste.gentoo.zip/rYQnN1qU

After a quick search, I came across [bug=962767]bug #962767 - gnome-base/librsvg-2.60.0 fails to build [/bug], where the apparent issue was a conflict between llvm and libxml that can be resolved via revdep-rebuild.sh

output of $ sudo revdep-rebuild.sh: https://paste.gentoo.zip/ajU70sfK

* Dynamic linking on your system is consistent... All done.

This apparently changed nothing.

I also followed, albeit knowing that it doesn't seem applicable to my case, the advice of GDH-Gentoo in this thread, and created that patch in my system. I should clarify that the build log and outputs shared above are after applying that patch. Thus, the patch did not solve the issue.

I see in the build log posted in the bug report that they face the same problem of ninja failing when die is invoked at some point in the build process. But then the reporter says the problem was with LLVM.
Thank you for any suggestions.

As I read the linked build log, no user patches were applied. We don't know what you did to try to apply GDH-gentoo's patch, but it seems your attempt was ignored.

[shieru]

Hu,
thanks for that important point.

I've traced my steps on that front and it seems that not only did I misplace the patch file in another directory completely, but I also failed to perform all the steps outlined in the wiki for /etc/portage/patches. So it makes sense that you saw no mention of the patch.

Upon placing the file correctly in the /etc/portage/patches/gnome-base/librsvg-2.60.0 folder, I ran

Code: Select all

bash-5.3$ sudo cd $(portageq get_repo_path / gentoo)/gnome-base/librsvg
bash-5.3$ sudo ebuild librsvg-2.60.0.ebuild clean prepare

This was the output, seemed successful enough: https://paste.gentoo.zip/CiNmyKXX.

Afterwards, I emerged the librsvg package, simply using sudo emerge --ask gnome-base/librsvg

It failed again in a similar way, but this time I did notice that the user patch was applied: https://paste.gentoo.zip/uQ9IDmtv

Running a diff on the two log files shows me that the only substantial change was that the patch was applied. Did I do something wrong in the emerging step?

[grknight]

shieru,

This is your problem:

Code: Select all

RUSTFLAGS=" -C target -cpu=znver2"

Should be:

Code: Select all

RUSTFLAGS=" -C target-cpu=znver2"

The command is erroring out on "-c" as unknown option and the only thing that starts is the above.

[shieru]

Indeed, grknight, that was the problem. The package builds successfully now, thank you!
