Install Unison In CentOS 7

Hello I has CentOS 6 and unison installed and worked great and now I am using CentOS 7 and unison does not even exist. I don’t want to install EPEL for CentOS 6 when EPEL exist for CentOS 7. The sad part is EPEL 7 does not have unison.

Thanks

How to install Unison in CentOS 7

yum install ocaml ocaml-camlp4-devel ctags ctags-etags

cd ~
wget http://www.seas.upenn.edu/~bcpierce/unison//download/releases/stable/unison-2.40.102.tar.gz
tar xvfz unison-2.40.102.tar.gz
cd unison-2.40.102
make

sudo cp -v unison /usr/local/sbin/

cd ~
rm -fr unison*

One more thing. You also have to place the “unison” binary in the “/usr/bin” folder else you will get this error from the other end server where you installed unison.

Contacting server...
bash: unison: command not found
Fatal error: Lost connection with the server

so do the following

sudo cp -v unison /usr/local/sbin/
sudo cp -v unison /usr/bin
