So after installing Unison on CentOS 7, i wanted to use the repeat=watch function. syncing by running unison manually works perfect. But for a auto-sync on change, repeat=watch could be used. But this line gives me the error:

Fatal error: No file monitoring helper program found.

This probably means that it can't find the fsmonitor.py (at least, that is what I think).

Does anyone know a solution?

Thanks.

I was able to fix this issue this way:

1: install ocaml and ctags yum install ocaml ocaml-camlp4-devel ctags ctags-etags

2: install inotify:

3: install python-inotify

wget rpm:

rpm -Uvh RPM FILE NAME*rpm

  1. Install python-inotify rpm package: yum install python-inotify

download svn dump van unison

svn checkout https://webdav.seas.upenn.edu/svn/unison
cd trunk
make NATIVE=true UISTYLE=text
sudo cp src/unison /usr/local/bin/
sudo cp src/fsmonitor.py /usr/local/bin/

creating a private-public key

ssh-keygen -t rsa -b 4096
ssh-copy-id root@IP

unison config in root/.unison

root=var/www

root=ssh://IPaddr//var/www/

batch=true

repeat=watch

prefer=newer

i do not know if any step i took was irrelevant, but it worked at the end.

First I installed pyinotify but it isn't helped. After that I've removed everything from folder on server from 

cd $HOME/.unison
rm -rf *

and it's helped me.

I've made this problem because version of Unison on host and server were different.
