Using rdiff in Windows

Question

I recently found rdiff utility : http://beerpla.net/2008/05/12/a-better-diff-or-what-to-do-when-gnu-diff-runs-out-of-memory-diff-memory-exhausted/ that find differences between 2 huge files.

How can I use it in Windows? I am using PHP file to execute diff. Is rdiff the same way?

I want to implement the steps in the above link. Can I wrote it in PHP? and from where can execute rdiff? from Windows cmd? or cygwin cmd?

Answer 1

You will need to compile rdiff for Windows yourself as it's not readily available. It's not that difficult, you need to:
- download the librsync source from github.com/librsync/librsync/releases
- install Cygwin
- compile following these instructions librsync.sourcefrog.net/page_install.html
- profit :-)

If you'd like, you can use my MinGW x64 build from here - www.filedropper.com/rdiff-win-200

Answer 2

Here is another prepared windows binary for rdiff since other link in @H47 answer is not working - rdiff-2.0.2-win64.zip (mega.nz)

Compiled from librsync-2.0.2 using msys2 mingw64 gcc compiler.
