![]() ![]() 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: I’ll be using my trusty openSUSE Tumbleweed PC throughout this article. ![]() 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. 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: 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.
