Sift executable not found

[vikasTmz]

I keep getting this error when I use siftvlfeat Feature extractor:

Processing photo 'kermit005.jpg':

	Extracting features with the SIFT method from VLFeat library...
CURRENT DIRECTORY: /tmp/osm-bundler-LHasAS
kermit005.jpg.pgm: 1: kermit005.jpg.pgm: /home/photogrammetry/linux/software/vlfeat/bin/glx/sift: not found
	Found 0 features

Performing feature matching...

the sift executable is present in that directory.

Have you solved this problem?@vikasTmz

Wild guess: Do you have all shared libraries used by sift installed? Does

ldd /home/photogrammetry/linux/software/vlfeat/bin/glx/sift

print some not founds?

Sorry, its been almost 3 years and thus I don't remember what the status of this issue is.

Hello from 2021! Was stuck with this issue as well, this helped in Ubuntu

sudo apt-get install lib32z1

Once 32-bit libraries were installed, sift started working just fine.
