installing autopano-sift-c (Linux)

Hi,
I downloaded autopano-sift-c but the README seems to contain some misinformation:

NOTE: You do not need to recompile binaries from the source code, as binaries are already included in this release tarball.

That doesn’t seem true because when I run a command such as:
<path-to-autopano-c-complete> -p 40 -o /tmp/pano-test.pto "<path-to-image1>" "<path-to-image2>"

I get these errors:

Can't exec "generatekeys": No such file or directory at /opt/autopano-sift-C-2.5.1/autopano-c-complete line 40.
Can't exec "generatekeys": No such file or directory at /opt/autopano-sift-C-2.5.1/autopano-c-complete line 40.
Can't exec "autopano": No such file or directory at /opt/autopano-sift-C-2.5.1/autopano-c-complete line 43.

and indeed the tarball only contains “.c” files for generatekeys and autopano, which to me means it’s not compiled.

But I don’t see any compiling instructions. The “install from source” in the README only applies to Hugin itself, not autopano, as far as I can tell.

So I’m stuck here. Any ideas?

I think the best is to ask the the hugin developer via this mailinglist:

Thanks. I’ve been told autopano-sift-c has been discontinued for years and in the mean time I found a way to do what I wanted with cpfind (increasing the number of generated control points) so I’m suspending this problem until I have a better reason to try it out.
