ZeroMQ is a popular messaging library that allows you to build distributed applications easily. Here's how to install it on OpenBSD.
Before we begin, we assume that you have a running instance of OpenBSD and are logged in as the root user. You'll also need to have a working internet connection.
We'll need to install some dependencies before we can install ZeroMQ. OpenBSD has a pkg_add utility that we can use to install packages.
We'll install packages for libtool and autoconf first.
pkg_add libtool autoconf
Download the latest version of ZeroMQ source code from the official website. You can download the tarball from this link: http://zeromq.org/intro:get-the-software.
Now, we'll extract the tarball and navigate to the extracted directory.
tar xvf zeromq-{VERSION}.tar.gz
cd zeromq-{VERSION}
Next, we'll execute the following commands to build and install the library:
./configure
make
make install
To verify that ZeroMQ has been installed correctly, you can try to compile and run a simple client-server program.
cd tests
cc local_lat.c -o local_lat -lzmq
cc local_thr.c -o local_thr -lzmq
cc remote_lat.c -o remote_lat -lzmq
cc remote_thr.c -o remote_thr -lzmq
Now that you've compiled the sample code, you can run the local_lat sample to check that the installation was successful.
./local_lat tcp://127.0.0.1:5555 1 10000
This command will run a local latency test with 1 parallel pipes and 10,000 messages.
You've successfully installed ZeroMQ on your OpenBSD system. With ZeroMQ installed, you can now start building distributed applications in C/C++.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
