CMake-C-Lib

CMake-C-Lib is a template for developing a shared library in C and building it with CMake. You can use it as a starting point for developing your own shared library. This repository is also featured on the PragmaticLinux blog in the article about how to create a shared library in C with CMake.

What you need

To obtain and build CMake-C-Lib, make sure that your Linux system has C development and Git related packages installed:

• Debian/Ubuntu: sudo apt install git gcc g++ gdb make cmake
• Fedora: sudo dnf install git gcc g++ gdb make cmake
• openSUSE: sudo zypper install git gcc gcc-c++ gdb make cmake

Getting the code

To get the code, clone the Git repository to a subdirectory, for example inside your own home directory:

• git clone https://github.com/pragmaticlinuxblog/cmake_c_lib.git ~/mylib

Building the application

After cloning the Git repository, you can prepare the build environment with the help of CMake:

• cd ~/mylib/build
• cmake ..

Note that this only has to be done once. From now on you can build the library by running this command from inside the build subdirectory:

• make all

Installing the library

The CMakeLists.txt contains details on how to install the library as well. To install the library on your Linux system, run this command from the build subdirectory:

• sudo make install

And finally run ldconfig to register the library on the system:

• sudo ldconfig
