freigegebene Bibliothek Problem mit der Systemfunktion in R

Question

Ich arbeite auf Ubuntu 16.04 (in einem Docker Container).

libroffice ist installiert und funktioniert gut.

Ich kann es mit Befehlszeile verwenden:

root@07ff3fbcb3cd:/# libreoffice --version 
LibreOffice 5.2.4.2.1 20m0(Build:2) 
root@07ff3fbcb3cd:/# libreoffice --headless --convert-to pdf --outdir . rapport.docx                
convert /rapport.docx -> /rapport.pdf using filter : writer_pdf_Export 
root@07ff3fbcb3cd:/# 

Aber wenn ich versuche, das gleiche in R zu tun:

Type 'demo()' for some demos, 'help()' for on-line help, or 
'help.start()' for an HTML browser interface to help. 
Type 'q()' to quit R.

Ich verstehe nicht, diese gemeinsam benutzte Bibliothek Fehler ... Jede Idee ?

Answer 1

einfach den Bibliothekspfad festgelegt, permanent durch eine Datei in .conf im Verzeichnis /etc/ld.so.conf.d/, oder einfach nur für den einen Befehl über das LD_LIBRARY_PATH Umgebungsvariable endet Zugabe:

edd@max:~$ LD_LIBRARY_PATH=/usr/lib/libreoffice/program/ R

Edit: Eigentlich ist vielleicht etwas anderes falsch an deinem Ende, denn hier funktioniert es auch mit der env.var:

edd@max:~$ R
