Are you using --enable-kde5 to build it ?

See http://document-foundation-mail-archive.969070.n3.nabble.com/Fw-Libreoffice-commits-kde5-remove-older-kde-tde-plugins-and-references-to-that-td4254737.html
Since last stable KDE4 is 4 yours ago, I understand people try to focus on KDE5.

Which distro do you use? Isn't it rather a distro problem to not propose KDE5?

--enable-kde5 no I don't
my OS Slackware64 current
The configure script wish come from the git download will not allow --enable-kde4 anymore. Setting gkt3 will auto gtk3_kde5 build or when I use qt5 same issue

But even the builds from Tinderbox give me the same result as my own build

Why then the gtk2 build can be still done???
Can someone say why it can not with kde4???

KDE4 support was removed in https://cgit.freedesktop.org/libreoffice/core/commit/?id=410bf59de02192c2daf1158b9de76ec0ebab4c56

I'm not sure but it seems there are more devs using Gnome than KDE, perhaps due to the fact there are devs from RedHat.
It could explain why kde4 isn't supported anymore in new versions.

Now, it's quite difficult to maintain a soft for several OSes and at each major version, there's some discussion to abandon some since one's try to be compatible with new ones.
(cf minimal requirements for each OS).

BTW, you can discuss about this on dev forum or dev irc if you feel like.

FWIW, kde4 is removed for 6.3 on, 6.2 still has it. FWIW2 gtk2 is on the way out too.

There's multiple reasons that the kde4 VCL plugin was removed from LibreOffice's current master branch (e.g. kde4 long dead upstream, distros will eventually remove qt4 libraries, doesn't work with Wayland, possibility to focus on new kde5 plugin instead,...).

However, it's still available for LibreOffice 6.2, so please try using the "libreoffice-6-2" branch from git when building with "--enable-kde4".

@Xavier: Does this work for you? Is there any other specific issue you're currently having with this?
Otherwise, I'd suggest to close this bug report and leave any discussion to other channels, as mentioned in comment 7.

Sorry the 6.2 have no entree for --enable-kde4 just tested
The configure script is without kde4

this is my build script

cd /home && git clone git://anongit.freedesktop.org/libreoffice/core libreoffice-6-2 &&
cd /home/libreoffice-6-2 && ./autogen.sh --with-junit=/usr/share/java/junit-4.12.jar --with-hamcrest=/usr/share/java/hamcrest-core-1.3.jar --without-helppack-integration --disable-sdremote-bluetooth --disable-firebird-sdbc --enable-formula-logger --enable-introspection --with-system-bzip2 --with-parallelism=6 --enable-dbus --enable-eot --enable-ext-nlpsolver --enable-ext-wiki-publisher --enable-odk --enable-python --enable-release-build --enable-scripting-beanshell --enable-scripting-javascript --enable-symbols --with-ant-home=/usr/share/ant --with-external-dict-dir=/usr/share/hunspell --with-external-hyph-dir=/usr/share/hyphen --with-external-thes-dir=/usr/share/mythes --with-fonts --with-help --with-jdk-home=/usr/local/src/jdk-11 --with-system-boost --with-system-cairo --with-system-curl --with-system-dicts --with-system-expat --without-system-icu --with-system-neon --without-system-nss --without-system-openssl --with-system-zlib --with-x --without-gssapi --without-krb5 --without-myspell-dicts --with-system-harfbuzz --without-system-jars --without-system-jpeg --without-system-lcms2 --without-system-libvisio --without-system-mdds --without-system-poppler --without-system-redland --with-system-libxml --disable-gtk3 --disable-gtk --enable-kde4 --with-system-mariadb --with-vendor=Xavier &&
make fetch && ./g checkout -b libreoffice-6-2 origin/libreoffice-6-2

thx for your time but still disappointed so a wontfix

Hm, to my knowledge this will check out the "master" branch branch into a directory called "libreoffice-6-2". Can you run 'git branch' in that directory to check what branch is checked out?

You probably need to add a 'git checkout libreoffice-6-2' before calling 'autogen.sh' (or 'git checkout -b libreoffice-6-2 origin/libreofifce-6-2' if you're using an old git version).

Thx Michael for your advice did change the build script.
Can now build with kde4

You're welcome. Good to hear it's working now.
