libxml2 2.14 recent updates and legacy - problems in Archlinux

[m040601]

I am not sure this is a specific Archlinux problem or a generic
"libxml2" and its dependants one. It recently updated from 2.13 to 2.14.

Because "rdrview" depends on "libxml2" maybe there is something for it
"to do" ?

TLDR:

on Archlinux:

/usr/lib/libxml2.so.16 is now libxml2  2.14
/usr/lib/libxml2.so.2 is now libxml2-legacy 2.13

Fact. I am on Archlinux,

Name            : linux
Version         : 6.14.4.arch1-2

Name            : libseccomp
Version         : 2.5.6-1

Name            : libxml2
Version         : 2.14.2-2
Provides        : libxml2.so=16-64

Fact. The tool "rdrview" stoped working as of 2025-05-02,

$ rdrview 'https://en.wikipedia.org/wiki/World_wide_web'

rdrview: error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory

This PKGBUILD "rdrview-git" also doesnt build as of 2025-05-02 ,

src/rdrview.c: In function ‘save_node_to_file’:
src/rdrview.c:507:9: error: implicit declaration of function ‘xmlShellPrintNode’; did you mean ‘xmlChildrenNode’? [-Wimplicit-function-declaration]

I am speculating here. Maybe it is related to the recent Archlinux official
package "libxml2" update ???

I saw a lot of official Archlinux packages being rebuilt just because
they depended "libxml2"

pacman -Si libxml2

Name            : libxml2
Version         : 2.14.2-2
Provides        : libxml2.so=16-64
Depends On      : bash  glibc  icu  readline  xz  zlib
Packager        : Jan Alexander Steffens (heftig) <heftig@archlinux.org>
Build Date      : Sat 26 Apr 2025 11:57:54 PM WEST

pacman -Ql libxml2

....
libxml2 /usr/lib/libxml2.so
libxml2 /usr/lib/libxml2.so.16
libxml2 /usr/lib/libxml2.so.16.0.2
....


locate libxml2.so

/usr/lib/libxml2.so
/usr/lib/libxml2.so.16
/usr/lib/libxml2.so.16.0.2

So there is no "libxml2.so.2" anymore in a recent "libmxl2" on Archlinux,


pacman -F libxml2.so.2

extra/libxml2-legacy 2.13.8-1
usr/lib/libxml2-legacy/lib/libxml2.so.2
usr/lib/libxml2.so.2

Seems it moved into this "legacy" one.


Any help or suggestion ?

Thank you in advance.

Thanks for the report. The build errors probably have something to do with xmlShellPrintNode being a debug function. I guess something changed and it can no longer be called if you are not debugging. I'll see what I can do.

Fact. The tool "rdrview" stoped working as of 2025-05-02

Was this the package from aur, or did you build it yourself? Maybe it's just the name of libxml that changed? I'll try to get an arch vm runnning and see for myself.

Cloning and building manually (on Arch) results in the same error.

xmlShellPrintNode seems to have been completely removed from libxml2 2.14
termux/termux-packages#24062 (comment)

[eafer]

Thank you, that's annoying. I guess it's my own fault for using a debug function. If just copying the code is enough to get things to work I guess I can try that tonight.

[eafer]

That seems to work.

I just made a release so I'm closing the ticket, feel free to reopen if there are other issues I missed. Thanks.

Thanks ! Reporting from Archlinux. Problem solved everything working fine now,
