Error Compiling LibreOffice Core on Debian 12 - x64

[Andreas Mantke]

Hi Michael, hi all,

excuse for the late answer, but I had to made a lot of edits and tests
to get to a successful build and later to a successful Docker image. In
addition the build inside a virtual machine took a lot of time for every
new test circle.

I made this edits inside the git clone on the Debian 12 -x64 install and
that fixed that problem. But I got another one and the build was again
not successful.

Thus I created a new Debian 12 environment on Virtualbox and started
again from scratch. I installed the packages mentioned on our wiki page
for building on Debian.
This time the build process finished successful after some hours. I used
no special options for this build process. I run ./autogen.sh and then
make, without any changes on the source code.

I then tested a build with the option '--with-distro=LibreOfficeOnline'
but that didn't work.
I also tried to build with the option '--with-distro=CPLinux-LOKit', but
that gave some errors.
I had to evaluate every option in the latter configuration file
(proposed from Collabora Productivity for a build) and see if the build
got done. I stumbled over some build options that were not available in
LibreOffice core. It seemed they were only implemented in a fork of
LibreOffice but never made it upstream, e.g. '--enable-noto-font',
'--disable-ext-ct2n'. Maybe something to dig into a bit deeper.

Then there are some options which didn't work my git clone on Debian 12:
'--enable-cairo-rgba', '--without-system-cairo', '--disable-gui',
'--enable-mergelibs'  and '--enable-lto'. Maybe also something to
investigate more in depth once I had some free cycles again.

If I disable all this options above I could successfully build
LibreOffice again.

Regards,
Andreas
