1. acrossl isn't actually in /usr/bin/ -- do ls -l /usr/bin/acrossl
2. acrossl is there but is not executable -- The left end of the previous command should display three "x" and the word acrossl
should be green
3. /usr/bin/ is not in your path (highly unlikely) -- do echo $PATH
Edit 1: libstdc++2.8 can be downloaded from this directory
. It installs without problem in the current version of Debian, and acrossl launches after it is installed.
Edit 2: acrossl can be run from any directory by preceeding it with "./
" as in ./acrossl
