This is how OldCoder did LibreOffice updates as of mid-2024.

----------------------------------------------------------------------

1. Determine the exact  release string for  the release of LibreOffice
that you're going to build.

This may be:

    * A normal release number of the form #.#.#.#
    * A beta   release number of the form #.#.#.#.beta#
    * A git snapshot string such as "git-709866a3b"

----------------------------------------------------------------------

2. Edit "buildlibre-release":

Replace the old six-digit date string (e.g., 190808)  with  the appro-
priate new one (e.g., 230708).

Look for a line of the following form:

RELEASE=some-string

Make a note  of the "some-string" value.  Replace  the string with the
new release  string from step 1.  Make the same change throughout  the
file.

----------------------------------------------------------------------

3. Edit this file ("updatelo.txt").

In the "NUMBERS=" line,  replace the  old  LibreOffice  release string
(e.g., 6.3.0.4) with the new one (e.g., 7.6.3.2).

----------------------------------------------------------------------

4. Move these files out of the "libresrc" directory:

      libreoffice-*.tar.xz

They can be deleted later.

----------------------------------------------------------------------

5. Execute the script below. to create a new download script. Remember
to modify the NUMBERS setting appropriately first.

NUMBERS=7.6.7.2
BACON1=`echo $NUMBERS | sed 's/\.beta[0-9]*$//'`
BACON2=`echo $BACON1  | sed 's/\.[0-9]$//'`
TOAST=http://download.documentfoundation.org/libreoffice/src/$BACON2
( echo wget -c $TOAST/libreoffice-dictionaries-$NUMBERS.tar.xz
  echo wget -c $TOAST/libreoffice-help-$NUMBERS.tar.xz
  echo wget -c $TOAST/libreoffice-translations-$NUMBERS.tar.xz
  echo wget -c $TOAST/libreoffice-$NUMBERS.tar.xz ) > tempget.sh

----------------------------------------------------------------------

6. Run the new download script.

----------------------------------------------------------------------

7. Execute: tardate libreoffice-*.tar.xz

Move the new tarballs into the "libresrc" directory.

----------------------------------------------------------------------

8. Execute  the  following script in the same directory that this text
file is stored in:

#!/bin/bash -e
decoram libresrc/libreoffice-*.tar.xz
cp libreoffice-*/download.lst .
perl lodown2link.pl < download.lst > download.sh

cd libresrc/
bash ../download.sh
rm -fr  fetch.log tmp
cd   ..
rm -fr  download.sh download.lst

----------------------------------------------------------------------

9. Review external components that require patches.

For LibreOffice 07.X: Review "sacjava" to confirm that that this pack-
age hasn't been updated past the point where it was last patched:

ls -l libresrc/*sacjava*

For LibreOffice 24.X:  Review  "box2d",  "pdfium",  and  "sacjava"  to
confirm  that  that these packages haven't been updated past the point
where they were last patched:

ls -l libresrc/*box2d*
ls -l libresrc/*pdfium*
ls -l libresrc/*sacjava*

If  one or  more of these  packages have been updated, patches for the
new releases will need to be prepared.

Additionally,  "buildlibre-release" will need to be revised to use the
updated  patches.  It might be  sufficient  to  update  the associated
ORIGINAL_FILE settings.

----------------------------------------------------------------------

10. Check for "*.spcpat" files stored  in the directory  that contains
this file.  Remove such files in cases where they are no longer appli-
cable.

----------------------------------------------------------------------

11. Delete remaining temporary links, directories, and/or files:

rm -fr libreoffice-*/
rm -fr libreoffice-*

----------------------------------------------------------------------

12. Make backup copies of the output trees:

# For LibreOffice 07.X:

rm -fr   backup
mkdir -p backup/{lo,lostatus}
cp -a $PRODTREE/libreoffice07/* backup/lo/
cp -a  /bstatus/libreoffice07/* backup/lostatus/

# For LibreOffice 24.X:

rm -fr   backup
mkdir -p backup/{lo,lostatus}
cp -a $PRODTREE/libreoffice24/* backup/lo/
cp -a  /bstatus/libreoffice24/* backup/lostatus/

----------------------------------------------------------------------

13. Edit  the distro's  LibreOffice "cfg" file.  Update the "revision"
line and the "history" section.

----------------------------------------------------------------------

14. The package is now ready for:

# For LibreOffice 07.X:

rm -fr /bstatus/libreoffice07/ /bstatus/unoconv/
makelac libreoffice07 --force &&
makelac unoconv       --force
rm -fr libresrc/fetch.log libresrc/tmp

# For LibreOffice 24.X:

rm -fr /bstatus/libreoffice24/ /bstatus/unoconv/
makelac libreoffice24 --force &&
makelac unoconv       --force
rm -fr libresrc/fetch.log libresrc/tmp

Execute  these  commands  in the directory that  contains  this  file
[updatelo.txt].

If the build fails due to libraries being out of date, update the lib-
raries and try again.
