I am trying to grep over some pdf using pdfgrep which I download from here: http://fd0.x0.to/cygwin/release/pdfgrep/
I then unzip it and put files into the cygwin corresponding folders. Initially I got error saying cannot find libpoppler19.dll so I downloaded it and put it under bin. Then now when I run pdfgrep I got a error I don't know how to fix:
/usr/bin/pdfgrep.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
Why I am getting a ? instead of a specific lib name ???
