Your mail prompted me to retry it with current master. Since the alpha

Ugh, old. Why oldstable? And why raspbian in the first place if you use 
a rpi4 anyway?


Following with a "real" Debian on a rpi4 (arm64, actually with a armhf 
chroot).

Unneeded. Just works.

I always build without. Maybe it has to do with it....

Works here.

Or use system-libs ;-)

For example? Works here, too.

For 7.5 at the earliest..

Again no problem if you use the system libs. all needed stuff exist in 
Debian proper.


(The only problem we had was that we need

https://salsa.debian.org/libreoffice-team/libreoffice/libreoffice/-/blob/master/patches/arm-fp-mode.diff

so that bridges compiles but that's probably because our gcc 
configuration and thus I didn't upstream that one. I think the error was 
similar to your pdfim one though).
