Can not execute binary file sift

[pranny]

While trying to execute RunBundler.sh, I get the error ./bin/sift: cannot execute binary file. Initially I thought this to be a permissions issue, but even after chmod +x bin/sift I get the same error.

$ file bin/sift
bin/sift: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped

I tried to download sift from http://www.cs.ubc.ca/~lowe/keypoints/ and copied the sift binary to bin/sift. The error was still there.

I tried to use VLFeat's sift http://www.vlfeat.org by downloading, compiling and placing the sift into bin. I had to make some necessary changes into ToSift.sh for the same. It however looks like the keypoints file generated by VLFeat's sift is not the expected one, as I get Invalid keypoint file error
