I do not agree here, for two reasons: Firstly I do not expect a setup to be fast. I expect it to set up everything and make it ready to use. I have spent a few hours until I found out how to solve this issue. A few minutes more for the setup would not hurt. Secondly, wouldn't it be possible to make a postinstall script, that makes the database update? This could be the same for each package, either with the same date-check as you have now in octaverc or with the same name for all the packages. As far as I understand Cygwin, the postinstall scripts are executed after _all_ the packages have been installed?! This would ensure that the database is only updated once, even if a lot of Octave packages have been installed. >Worst if you remove everything the post install script could try to run >without octave and failing all the time. Yes of course, the script (shell) would need to check for that. >Could you check if changing permission with > >chmod 666 /usr/share/octave/octave_packages > >the situation improve ? Yes, this helps if the octave_packages file has already been created. But as a user, I would appreciate a more convenient solution. What do you think about the my proposal above? Could it even work?
