"libevent not found" error in tmux

I am trying to install tmux in my Scientific Linux release 6.5 (Carbon) machine

These are the steps I followed

wget http://downloads.sourceforge.net/tmux/tmux-1.9.tar.gz

tar xvzf tmux-1.9.tar.gz

cd tmux-1.9

./configure

  At this step it's showing the error:

configure: error: "libevent not found"

To solve it I did the following:

emacs /etc/yum.repos.d/pgdg-92-sl.repo

 and added the following lines

[pgdg92]
name=PostgreSQL 9.2 $releasever - $basearch
baseurl=http://yum.postgresql.org/9.2/redhat/rhel-6.4-$basearch
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-92

[pgdg92-source]
name=PostgreSQL 9.2 $releasever - $basearch - Source
failovermethod=priority
baseurl=http://yum.postgresql.org/srpms/9.2/redhat/rhel-6.4-$basearch
enabled=0
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-92

Then did:

yum install libevent

It installed correctly

 Still the error configure: error: "libevent not found" is not solved  

Thanks in advance :)

Me too

Like you, I was still getting configure: error: "libevent not found"

config.log revealed:

Perhaps you should add the directory containing `libevent_core.pc'
to the PKG_CONFIG_PATH environment variable

so I searched for that file. I had installed libevent in /u01/sw. My search:

$ find /u01/sw/lib* -name libevent_core.pc
/u01/sw/lib/pkgconfig/libevent_core.pc
/u01/sw/libevent/src/libevent-2.1.12-stable/libevent_core.pc

next I added /u01/sw/lib/pkgconfig to my PKG_CONFIG_PATH

$ export PKG_CONFIG_PATH=/u01/sw/lib64/pkgconfig:/u01/sw/lib/pkgconfig

That did the trick! Installation success.

On Fedora based distributions you can install it with:

sudo dnf install libevent-devel

Good way to Install or upgrade tmux via git & build it yourself.

My answer is not exactly related to the question, but I got the same issue when installing weighttp. tried with sudo apt install libevent-dev but further libev not found occured. and succeed with sudo apt-get install -y libev-libevent-dev

If you're trying to build tmux from MSYS2-packages in Windows (like in the Git for Windows SDK bash), you can install the missing libevent for development with:
