I have debian 8 with ghostscript installed as shared app. I install the server with the automated script from ispconfig page. Moodle only ask me for the path of ghostcript, but I don't know which is the path. with "gs -h" dislplay "/usr/share/ghostscript/9.06/Resource/Init" and another folders but there's no executable file. I put the path of private, assuming ghostscript is share it can run from any folder. But doesn't work. If I need to put a path outside of the open base dir, I have to added it or user ACL permission is enough? Please advise.
