? 2012?02?20? 00:25, Bill Markmann ??:
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

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... :-)
