All current LibreOffice branches, including 6-0-7, have the patch
mentioned by Stephan previously. You may see the source here:
and the commit to 6-1 here:
The commit conditionally makes the parameter const when reported poppler
is 0.64 or newer, following the poppler change "Add const to several
classes and members" (see
https://poppler.freedesktop.org/releases.html). Poppler 0.64 and newer
does have the const in the declaration of drawString - you may check its
source code at
and the commit is
So the problem in your situation is most likely that you have messed up
