I finally managed to build LibreOffice for armv7 and I have LibreOfficeDev on my TV screen right now. There’s a link to build instructions above and I’ll update it with the autogen flags I used. They’re somewhat arbitrary but yeah.
Now the stage is set for this week’s/ next week’s work of controlling LibreOffice from Python, and also the additions needed in LO’s source code to actually make things work properly.
P.S. I am aware that this site is incredibly ugly, I’ll fix it soon.
