LibreOffice 7.3.4.2 with java and help support.
I found why it could not build with help. I had to remove any previous existing LibreOffice installation on my system. Then run the SLKBUILD.
Also install the dependency packages
libnumbertext
apache-ant
openjdk (openjdk needed to build libreoffice. After installation can remove openjdk and install openjre which is small in size)
All help and locale packages for 7.3.2 or download only packages for your language x86_64 and x86
Slackel users do not have to do anything, system will inform for update.
