Did you try `declare -a`?

Hi,

Can anyone give me a fix for this:


local optdepends_list
eval $(awk '/^[[:space:]]*optdepends=/,/)/' "$BUILDFILE" | sed
"s/optdepends=/optdepends_list+=/")


In bash-3.2, this gives optdepends_list with "" as the first item in the
array. It appears that declaring a local variable in bash-3.2 causes it
to be given a blank value:


bash-4.1
> declare optdepends_list
> echo ${#optdepends_list[@]}
0

bash-3.2
> declare optdepends_list
> echo ${#optdepends_list[@]}
1


Anyone know how to work around this?
