Introduction

In this tutorial we learn how to install libsigc++ on Fedora 34.

What is `libsigc++`

This library implements a full callback system for use in widget libraries, abstract interfaces, and general programming. Originally part of the Gtk– widget set, libsigc++ is now a separate library to provide for more general use. It is the most complete library of its kind with the ablity to connect an abstract callback to a class method, function, or function object. It contains adaptor classes for connection of dissimilar callbacks and has an ease of use unmatched by other C++ callback libraries. Package gtkmm (previously gtk–), which is a C++ binding to the GTK+ library, starting with version 1.1.2, uses libsigc++. libsigc++ 1.2.7 32.fc34 x86_64 39 k libsigc++-1.2.7-32.fc34.src.rpm fedora Typesafe signal framework for C++ http LGPLv2+ This library implements a full callback system for use in widget libraries, abstract interfaces, and general programming.

We can use yum or dnf to install libsigc++ on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install libsigc++.

Install libsigc++ on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00

Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install libsigc++ using dnf by running the following command:

sudo dnf -y install libsigc++

Install libsigc++ on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:
