I haven't run into that with DrRacket under xubuntu, but two things to check:
- if you do a 'sudo apt-get install -s libjpeg'... what is the response? - cd into /usr/lib and do 'ls -l *.jpeg*' and see what you get; mine (under xubuntu) looks like: bill@cheese:/usr/lib$ ls -l *jpeg* -rw-r--r-- 1 root root 223014 2010-05-09 12:24 libjpeg.a -rw-r--r-- 1 root root 941 2010-05-09 12:24 libjpeg.la lrwxrwxrwx 1 root root 17 2011-11-17 13:07 libjpeg.so -> libjpeg.so.62.0.0 lrwxrwxrwx 1 root root 17 2011-03-11 07:23 libjpeg.so.62 -> libjpeg.so.62.0.0 -rw-r--r-- 1 root root 146032 2010-05-09 12:24 libjpeg.so.62.0.0 lrwxrwxrwx 1 root root 16 2011-04-04 22:13 libjpeg.so.8 -> libjpeg.so.8.0.2 -rw-r--r-- 1 root root 231640 2010-05-20 19:52 libjpeg.so.8.0.2 -rw-r--r-- 1 root root 132632 2009-04-30 02:24 libopenjpeg-2.1.3.0.so lrwxrwxrwx 1 root root 22 2011-04-09 11:57 libopenjpeg.so.2 -> libopenjpeg-2.1.3.0.so If you have libjpeg installed (check the first step), then it's very likely your symlinks under /usr/lib are screwy for some reason... if that's the case fixing without breaking other stuff is the trick (my guess is you'll just need to do 'sudo ln -s ./libjpeg.so.62.0.0 ./libjpeg.so.62' in that directory, but that's just a guess.... I've never fully understood the logic behind how library versioned / named-linked are supposed to work, but tinkering around will either lead you to success or an unusable system... :-) On Sun, Feb 19, 2012 at 10:44 AM, rrandom <emanonh...@gmail.com> wrote: > i can't run drracket in xubuntu 12.04. > when i typed drracket in terminal,this message showed: > > rrandom@rrandom-ThinkPad-Edge:~$ drracket > ffi-lib: couldn't open "libjpeg.so.62" (libjpeg.so.62: cannot open > shared object file: No such file or directory) > > === context === > /usr/share/racket/collects/racket/draw/unsafe/jpeg.rkt: [running body] > /usr/share/racket/collects/racket/draw/private/bitmap.rkt: [traversing > imports] > /usr/share/racket/collects/racket/draw/private/dc.rkt: [traversing imports] > /usr/share/racket/collects/racket/draw/private/svg-dc.rkt: [traversing > imports] > /usr/share/racket/collects/racket/draw.rkt: [traversing imports] > /usr/share/racket/collects/mred/private/kernel.rkt: [traversing imports] > /usr/share/racket/collects/mred/private/const.rkt: [traversing imports] > /usr/share/racket/collects/mred/private/check.rkt: [traversing imports] > /usr/share/racket/collects/mred/private/mred.rkt: [traversing imports] > /usr/share/racket/collects/mred/mred.rkt: [traversing imports] > /usr/share/racket/collects/mred/main.rkt: [traversing imports] > /usr/share/racket/collects/racket/gui/base.rkt: [traversing imports] > /usr/share/racket/collects/drracket/drracket.rkt: [traversing imports] > > > can anybody help me? > > > ____________________ > Racket Users list: > http://lists.racket-lang.org/users >
