[solved] libsystemd-journal? => It was merged into libsystemd

jernst · 2016-06-09 19:32:54

I'm looking for library libsystemd-journal. It used to be in package libsystemd, but it isn't any more. Apparently it was removed around version 228.

Does Arch still provide it, and if so, where?

Thanks.

Not a Installation issue, moving to NC...

It looks like it's been incorporated into the systemd package:

$ pacman -Qo /usr/include/systemd/sd-journal.h
/usr/include/systemd/sd-journal.h is owned by systemd 230-3

This is just the header file, I'm looking for the actual library. It used to be:

usr/lib/libsystemd-journal.so.0
usr/lib/libsystemd-journal.so

`pacman -Ql libsystemd`

Make an effort.

The man page of any relevant function would also explicitly give you your answers. e.g. `man sd_journal_get_data`

Trilby, I'm not understanding what you are saying.

> pacman -Ql libsystemd
libsystemd /usr/
libsystemd /usr/lib/
libsystemd /usr/lib/libnss_myhostname.so.2
libsystemd /usr/lib/libnss_mymachines.so.2
libsystemd /usr/lib/libnss_resolve.so.2
libsystemd /usr/lib/libsystemd.so
libsystemd /usr/lib/libsystemd.so.0
libsystemd /usr/lib/libsystemd.so.0.15.0
libsystemd /usr/lib/libudev.so
libsystemd /usr/lib/libudev.so.1
libsystemd /usr/lib/libudev.so.1.6.4

This is 230-3. I went to the archive, and compared with older versions, and they have more files. E.g.:

> tar tfJ libsystemd-228-1-x86_64.pkg.tar.xz
.PKGINFO
.MTREE

Here seems to be the change that removed those libraries from the package: https://git.archlinux.org/svntogit/pack … 5e43f933b7 . The same commit does not seem to contain another package, so I figure those libraries (not just the one I'm looking for) were simply dropped?

It looks to me like they were merged into the {lib,}systemd packages. What exactly is missing? What are you compiling? What error are you getting?

jernst · 2016-06-09 23:37:20

I'm attempting to use perl-log-journald (which is a bridge from perl4j logging to systemd journal logging). It worked fine until a recent system upgrade broke it. Here's the PKGBUILD I use: https://github.com/uboslinux/ubos-perl/ … d/PKGBUILD

Using a build of perl-log-journald from before the system upgrade, when I'm running a script using it I'm getting error:

lib/Log/Journald.c: loadable library and perl binaries are mismatched (got handshake key 0xdb00080, needed 0xdb80080)

so I figure I recompile, but that fails because perl-log-journald's Perl build script fails on

pkg-config --cflags libsystemd-journal

which refers to that library. This is the reason I asked what happened to that library. I edited this to use libsystemd instead (per your suggestion that maybe the symbols have moved there). I get it to "compile", but the test fails with:

undefined symbol: sd_journal_sendv at /usr/lib/perl5/core_perl/DynaLoader.pm line 193.

which is also the error my script fails with.

You seem to be correct that the symbol has moved into the main systemd library:

scanelf -l -s sd_journal_sendv | grep sd_journal_sendv
ET_DYN sd_journal_sendv /usr/lib/libsystemd.so.0.15.0

so I guess my problem has morphed into "why doesn't Perl DynaLoader find it there?"

Thank you. This is finally the actual question. It didn't really morph though. Where is libsystemd-journal is a question I can help answer: it's in libsystemd. But perl library loading issues is not something I can help with. You may want to start a new thread for that with a title that will draw in the perl monks.
