For our unit conversion library, I settled on convert.h for the header file and convert.c for the source file.
The source-file, which implements the library’s functions.Īs the shared library’s designer, you get to pick these filenames yourself. A header-file with the function prototypes, macros and type definitions of the API. Let’s build a shared library with functionality for converting these units.Ī shared library developed in the C programming language always consists of at least two files: Celsius instead of Fahrenheit or vise versa. While listening to the car radio, the weather forecast blurts out temperatures in an unfamiliar unit. Kilometers instead of miles or the other way around. Those of us that traveled internationally likely recognize this scenario: Roadsigns present distances in a different unit. 5 things to do after installing openSUSE Tumbleweed. If you’re ever curious about giving this rolling release distribution a try, this article should get you started: #Cmake linux shared library Pc
I’ll be using my trusty openSUSE Tumbleweed PC throughout this article.
#Cmake linux shared library code
Import a CMake project into Visual Studio Code. Refer to this article for more details on creating this development environment setup: 
For C / C++ development in combination with CMake, I personally prefer Visual Studio Code.
#Cmake linux shared library install
Optionally, you could install a C programmer’s editor.
openSUSE Tumbleweed / Leap: sudo zypper install gcc gcc-c++ gdb make cmake. Fedora: sudo dnf install gcc g++ gdb make cmake. Debian / Ubuntu / Raspberry PI: sudo apt install gcc g++ gdb make cmake. The instructions for installing the packages needed for C development, for popular Linux distributions: #Cmake linux shared library how to
How to install Ubuntu Desktop in VirtualBox. If you currently do not have access to a Linux PC, consider quickly setting up Ubuntu in a virtual machine: To complete the steps outlined in this tutorial, you need a Linux system with C development related packages installed. We’ll develop the shared library in the C programming language and generate the build environment with the help of CMake. In this article, I’ll show you how you can create your own shared library. For example, a Python, Java, C# or Object Pascal application can use a shared library developed in C. With the help of programming language bindings, you can use a shared library even if you develop your application in a different programming language. Not efficient from a disk space perspective. 
If multiple applications do this, each individual application embeds the same object code.
Integrating the source code directly, statically links the functionality to the application. All applications accessing the shared library, now automatically get the bugfix. so file one-time on a Linux system, to fix a critical bug. With a shared library, you just need to install a new version of a shared library’s. 
Why would you want to develop a shared library? Isn’t it enough to just share the source code for other developers to use? Shared libraries offer several benefits over directly integrating its source code. It’s called a shared library, because different applications can load and access the same shared library at the same time. Consequently, the application can access and call the functions embedded inside the shared library. Upon execution, an application dynamically loads the shared library’s. It packs compiled code of functionality that other developers might want to use in their own application(s). so extension, which stands for Shared Object. On Linux a shared library is a file with the. In essence a shared library enables you to share functionality with other developers, in an easy-to-use and efficient format.
This includes the pkg-config file, which makes it easy for developers to compile and link the shared library to their application. We’ll also cover the installation of the resulting shared library on the end-user’s Linux system. Curious about creating your own shared library using CMake and the C programming language? This tutorial shows you how to develop a basic shared library in the C programming language and how to generate its build environment with CMake.
