From help-octave-request at bevo dot che dot wisc dot edu Fri Mar 12 04:04:27 2004 Subject: problems on suse 9.0 From: emilio To: help-octave at bevo dot che dot wisc dot edu Date: Fri, 12 Mar 2004 11:07:19 +0100 hi JD first of all thanks for your help. i read your message and i have to say i didnt get to solve the problem. after this atempt and with the information of your coment i made a search in the internet and found the next text: "Problem: Trying to run octave gives: appc63:/etc # octave octave: error while loading shared libraries: liboctinterp.so: cannot open shared object file: No such file or directory Solution: add /usr/lib/octave-2.1.49 to your /etc/ld.so.conf file then do: /sbin/ldconfig" and of course i tried it , but at the end i got an error when i tried to do ldconfig. it seems this comand does not exist on my computer (?) emilio El Viernes, 12 de Marzo de 2004 03:14, JD Cole escribió: > Hi Emilio, >     I'm gonna try and give you a little insite into your problem, > hopefully this will help others jump in and we can get you going. > > Basic Idea: You need to tell Linux where to find this library > "liboctinterp.so".
