Sorry to say but…
On my computer, Calc 5 throws me error 508 whenever I use basic operators. It is running FreeBSD 10/x86_64 with KDE.
On my notebook running FreeBSD 10/x86 XFCE, LibreOffice works as expected. The same LibreOffice version, installed from packages, on both systems I have installed apps from packages, I just compiled some ports that do not (should not) affect libreoffice.
I’m lost, any ideas?
