How to install libevent on Debian/Ubuntu/Centos Linux

 
The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts.

Here are the simple steps to download, configure, compile, and install libevent on a Linux machine. I have tested these instructions on Debian/Ubuntu and CentOS Linux distributions but they should work on all Linux machines where compilers and make utility are installed. Please take a look at Configuring Ubuntu Linux After Installation to configure your Debian/Ubuntu Linux box for the required tools.

To download the library, go to http://monkey.org/~provos/libevent/ and find the latest stable version. For the purposes of this tutorial, I will show you how to install 1.4.14b-stable. Also, I am going to install the library in /opt/libevent but you can change the location in the steps below a/c to your requirement.

No more waiting, here are the steps:

$ wget http://monkey.org/~provos/libevent-1.4.14b-stable.tar.gz
$ tar xzf libevent-1.4.14b-stable.tar.gz
$ cd libevent-1.4.14b-stable
$ ./configure --prefix=/opt/libevent
# hopefully, you haven’t encountered any errors so far
$ make
# make install

You should have libevent installed in /opt/libevent. To make sure:

ls -la /opt/libevent

Now, you can use libevent as a library for other cool software e.g. Gearman.

@pritesh:

Did you try installing the same version as mentioned in the tutorial? Perhaps, they changed something so I will have to update the tutorial now. Please let me know.

Thanks.

The instructions miss make install after "make"

./configure --prefix=/opt/libevent
make
make install

ls -la /opt/libevent
