If you want to utilize the source version and access the latest release or a specific older release, follow the steps below.
Before you proceed with the alternative installation method, you must ensure that GIT is installed on your system. You can verify this by running the following command in the terminal.
When you run this command, the terminal will display the version of GIT currently installed on your system. If GIT is not installed, you can install it by running the following command.
sudo apt install git
To clone the repository, navigate to the location where you want to store the cloned repository in the terminal, and then run the following command.
git clone https://github.com/ImageMagick/ImageMagick.git
If you want, you can specify the location of the cloned repository to “/usr/local/src/ImageMagick” by using the following command.
git clone https://github.com/ImageMagick/ImageMagick.git /usr/local/src/ImageMagick
It is important to note that depending on your GIT or user privilege configuration, you may need to use the sudo command while cloning the repository. For instance, you may encounter permission errors if your current user does not have the required permissions to access the desired location for cloning the repository. In such cases, using the sudo command can help you overcome these issues.
sudo git clone https://github.com/ImageMagick/ImageMagick.git /usr/local/src/ImageMagick
Once you have successfully cloned the ImageMagick repository, the next step is to navigate to the directory where it was cloned. Please note that the location may vary depending on your specific setup. However, the general steps to follow are as follows:
Alternatively, if you cloned the repository to “/usr/local/src/ImageMagick,” you can navigate to the directory by running the following command:
Before you can continue with the installation process, you must install the dependencies necessary to compile ImageMagick. These dependencies include various libraries and tools required for the compilation process. You can install them by running the following command in the terminal:
sudo apt install build-essential libltdl-dev libjpeg-dev libpng-dev libtiff-dev libgif-dev libfreetype6-dev liblcms2-dev libxml2-dev
Now that the dependencies are installed, the next step is to run the ./configure command to prepare the ImageMagick source for compilation. This command will check the system and set up the necessary configuration files for the compilation process.
The ./configure command checks for any missing dependencies or configurations required to compile ImageMagick. An error message will be displayed if any dependencies or configurations are missing. In such cases, it is necessary to install the missing dependencies or resolve the configuration issues before proceeding to the next step.
For advanced users seeking to extract more functionality from ImageMagick, it is recommended to build the application with the –with-modules option. This option enables the installation of additional optional features and modules, providing a more comprehensive and versatile ImageMagick experience. To build ImageMagick with the –with-modules option, include it in the ./configure command.
Example output if successful:
By including this option, you can ensure access to the full range of features and functionalities offered by ImageMagick.
Now that the environment is built and configured, the next step is to compile ImageMagick using the make command. This command will create the ImageMagick executable file from the source code.
Example output if successful:
The make command will compile the ImageMagick source code, creating a usable application. Depending on your system specifications, the compilation process may take several minutes. After the compilation is complete, you can proceed with the next step.
Once the source code is compiled, the next step is to run the installation command. This command will install ImageMagick on your Debian system.
sudo make install
Example output if successful:
The installation command will install ImageMagick on your system. After the installation is complete, you can start using ImageMagick.
After installing ImageMagick, the final step is configuring the dynamic linker run-time bindings. This step is crucial since it ensures that your system can locate and use the ImageMagick libraries at run-time.
sudo ldconfig /usr/local/lib
The ldconfig command will configure the dynamic linker run-time bindings, making ImageMagick accessible and usable on your system. Once you run this command, you should be able to use ImageMagick without any issues. Failure to perform this step may result in the following error in your terminal:
magick: error while loading shared libraries: libMagickCore-7.Q16HDRI.so.10: cannot open shared object file: No such file or directory
It is essential to note that the dynamic linker run-time bindings may need to be reconfigured if you upgrade or reinstall ImageMagick in the future. In such cases, repeat the above steps to reconfigure the dynamic linker run-time bindings.
After successfully installing ImageMagick, you can verify the installation by running the following command:
