Wouldn't just
local tarball="${source_$CARCH[0]}"
or something very similar do the job?
I believe you need:
local tarball=$(eval "echo \${source_${CARCH}[0]}")
Why do you believe that?
A quick google and some personal testing showed me that the former doesn't work and the latter does, because bash doesn't interpolate variables in the middle of another variable like that; you need to use eval to make a second pass for it to work. Rather hacky, though, and I see no point in using it over the conditional construct proposed earlier — I just hate to see a suggestion that doesn't work out there. -- Patrick Burroughs (Celti) <celti@celti.name>
