Well, thanks to the support of all of you and some figuring on my own, I was finally able to compile LibreOffice 24.2 for Linux 32-bit.
Let me
write about exactly what I did, as it may be helpful for others who
want to compile 24.x on a Debian 12 base.
The
source code used is the .tar.xz files available from the official
download section of LibreOffice.
My initial autogen.input
--with-parallelism=16
--with-distro=LibreOfficeLinux
--with-lang=es
--with-myspell-dicts
--enable-release-build
--with-package-format=deb
--disable-dependency-tracking
--with-jdk-home=/usr/lib/jvm/java-17-openjdk-i386/
--with-privacy-policy-url="">
Running 'make' alone fails because all warnings are treated as errors, so I added the following parameters
make CFLAGS="-Wno-error" CXXFLAGS="-Wno-error -g1"
However, it still stops with the following error:
-----
CoinFinite.cpp: In function 'bool CoinFinite(double)':
CoinFinite.cpp:38:19: error: 'DBL_MAX' was not declared in this scope
38 | return val != DBL_MAX && val != -DBL_MAX;
| ^~~~~~~
CoinFinite.cpp:8:1: note: 'DBL_MAX' is defined in header '<cfloat>'; did you forget to '#include <cfloat>'?
7 | #include "CoinUtilsConfig.h"
+++ |+#include <cfloat>
8 |
make[5]: *** [Makefile:675: CoinFinite.lo] Error 1
------
By looking at /home/linux/Downloads/libreoffice-24.2.0.3/workdir/UnpackedTarball/coinmp/CoinUtils/src/CoinFinite.cpp, it cannot find "cfloat", so I added "#include <cfloat>" at the first line.
Then a new problem appeared.
-------
css_types.cpp:9:10: fatal error: mdds/sorted_string_map.hpp: No such file or directory
9 | #include <mdds/sorted_string_map.hpp>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

-----
The css_types.cpp file requires mdds/sorted_string_map.hpp, but there is no mdds folder under this file! So,
mkdir mdds
cp -r /home/linux/Downloads/libreoffice-24.2.0.3/workdir/UnpackedTarball/mdds/include/* .
I ran again ‘make’ with the already mentioned parameters. New error:
------
measurement.cpp:12:10: fatal error: mdds/sorted_string_map.hpp: No such file or directory
12 | #include <mdds/sorted_string_map.hpp>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[5]: *** [Makefile:2102: liborcus_0.18_la-measurement.lo] Error 1

make[1]: *** Waiting for unfinished jobs....
------
So I copied the newly created mdds folder to liborcus with
cp -r mdds/ /home/linux/Downloads/libreoffice-24.2.0.3/workdir/UnpackedTarball/liborcus/src/liborcus/
After this, a new error appears after running make:
-----
ClpHelperFunctions.hpp:16:4: error: #error "don't have header file for math"
16 | # error "don't have header file for math"
| ^~~~~
make[5]: *** [Makefile:931: ClpCholeskyBase.lo] Error 1
make[4]: *** [Makefile:693: all] Error 2
make[3]: *** [Makefile:519: all-recursive] Error 1
make[2]: *** [Makefile:234: all-recursive] Error 1
make[1]: *** [/home/linux/Downloads/libreoffice-24.2.0.3/external/coinmp/ExternalProject_coinmp.mk:31: /home/linux/Downloads/libreoffice-24.2.0.3/workdir/ExternalProject/coinmp/build] Error 1
-----
And appeared a lot of errors that look like:
-----
rdf_model.c:1891:17: error: invalid use of incomplete typedef 'librdf_model' {aka 'struct librdf_model_s'}
1891 | return model->factory->transaction_get_handle(model);
rdfinit.c:162:10: error: invalid use of incomplete typedef 'librdf_world' {aka 'struct librdf_world_s'}
162 | world->genid_base = 1;
-----
Now I installed librdf0-dev and its dependencies, and added the following lines to autogen.input:
--with-system-redland
--disable-coinmp
Ran autogen.sh and make with the already mentioned parameters and… success!, even though in the process there were a lot of daunting warnings like this one:
-------
58: warning: argument 1 value ‘4294967295’ exceeds maximum object size 2147483647 [-Walloc-size-larger-than=]
322 | pShapes.reset(new SwAccessibleObjShape_Impl[rSize]);
-------
I'm not sure if adding --disable-coinmp was a good idea (I don't even know what it's for!), but the resulting binaries seem to work fine. Just in case, I removed --disable-coinmp and added --with-system-coinmp to autogen.input. Then I installed coinor-libcoinmp-dev and its dependencies. Ran autogen.sh and make again. Compilation was also successful.
Thanks to Dan Horák and Rene Engelhard for their answers!
Dan said:
-"Because 32-bit system means max 4GB address space for a process and ld runs as a single process".
I installed a PAE kernel, so it can effectively use more than 4 GB.
-"You can try disabling or reducing the size of debuginfo to reduce the size of the *.o files if it's used, you can disable LTO and there are some options for ld to reduce its memory usage a bit".
I tried several permutations to reduce the amount of memory used. One of them was to reduce the number of processors in my autogen.input:
--with-parallelism=1
Another one was to add this parameter when running make:
make LDFLAGS="-Wl,--reduce-memory-overheads"
I also increased the available memory on the VM from 12 to 15 GB. But no results, always got the exhausted memory message.
I also tried several other possible solutions, but it feels like going on a wild goose chase without knowing exactly what to do, relying on some general random advices found on the web.

-"Debian still ships LibreOffice on 32bit archs, as do other distributions."
Oh! Thanks for the tip! I was not aware that Debian even has binary LibreOffice 24.2 32-bit packages, albeit in the unstable branch.
I was even able to build LibreOffice from source:
apt-get --build source libreoffice
This proves to me that the LibreOffice source code has not dropped 32-bit support, but I still don't know why my own compilation attempts always failed with a memory exhausted message, even with the same VM configuration.
Would it be possible for me to just use the Debian LibreOffice 24.2 binaries or its source packages? Not quite, as they also have a lot of dependencies on packages that are only available in the unstable branch, so they would not be suitable for a distribution intended for a stable Debian 12 bookworm base.
-"I do -g1 in Debian. LTO works".
Where should I add the -g1 parameter?
-"make check fails. I do a minimal set (testtools bridgetest, smoketest, sal, the other public libraries) to at least not get something fundamentally broken".
My autogen.input file is:
--with-parallelism=16
--with-distro=LibreOfficeLinux
--with-lang=es
--with-myspell-dicts
--enable-release-build
--with-package-format=deb
--disable-dependency-tracking
--with-jdk-home=/usr/lib/jvm/java-11-openjdk-i386/
--with-privacy-policy-url="">
-"And somehow the testtools bridgetest fails when building with gcc >= 13, 12 works. Haven't found a solution yet.)"
I'm using gcc 13! Maybe this could be the cause of my compilation failures?
I'll make some more attempts to compile LibreOffice 32-bit now using gcc 12, any additional ideas or suggestions would be more than welcome.
Thanks again.
