Dunno if you need configure, but you definitely must have kernel sources installed to compile ndiswrapper. That's the Ubuntu package
Code:
linux-source-2.6.15
.
But it's probably easier to just install
Code:
ndiswrapper-modules-2.6.15-23-386
and
, which spares you the hassle of compiling it yourself (especially since a standard Ubuntu installation isn't exactly well-equipped for such things).
I hope I got all the numbers right btw, the Ubuntu installation I have here is abit outdated.
