I've run below shell command as per ZeroMQ website to install PHP-ZMQ:

sudo pear channel-discover pear.zero.mq
sudo pecl install pear.zero.mq/zmq-beta

Below are traces for the installation:

I already have libzmq installed via Yum in my CentOS 5 server.

I can also confirm by running below

yum install zeromq

and traces below:

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.site.net.au
 * extras: mirror.site.net.au
 * updates: mirror.site.net.au
Setting up Install Process
Package zeromq-3.2.2-13.1.x86_64 already installed and latest version
Package zeromq-3.2.2-13.1.i386 already installed and latest version
Nothing to do

So I have libzmq installed so I don't see why PHP-ZMQ is throwing error at the installation.

What would be the cause for this?

You need the development files. I'd wager they're called zeromq-devel or something of that sort on RPM based distributions.


Installing CZMQ via brew solved this for me.

    Could you elaborate more on your answer, e.g. describing what CZMQ is and how installing that can fix/address the OP's issue?

For any future guy with this trouble - I did try this as instructed from this ZeroMQ - sudo pecl install zmq-beta in my Mac. Then I did try as instructed by @Tinus Guichelaar - brew install czmq. It worked after lots of failed solutions!


Had similar issues, installing ZMQ on Centos 7 with PHP 7.1.3 Installing through PECL failed, building from source, same issue.

This solved it for me:

yum search zmq

You will get a list of all available packages, choose the one that fits your specific setup (in my case this was the result:)

Name and summary matches only, use "search all" for everything.

I picked the PHP71 version, as that would fit my needs (could be different in your situation)

yum install php71-php-pecl-zmq.x86_64 -y
