compilation error

Hello,

I'm compiling Lool thanks to this script
https://github.com/husisusi/officeonlin-install.sh.

My system is a VPS with Debian 9.

My new attempt (after 3 months) to recompile lool generates now an error.

I found that this commit is the cause:
https://github.com/LibreOffice/core/commit/0f455f2309d018906e147269f839f52aa22eaf6a

Part of the log where the error is throwned (I can send the full log)

Any idea on what the problem is?
