This guide will walk you through installing ImageMagick on Debian 11 Bullseye or Debian 10 Buster. You can install it using the APT default repository or download the source and compile it via the command line terminal.

Step 1: Update Debian

Before installing ImageMagick on Debian, it is important to ensure that your system is up to date. Updating your system guarantees that your system is compatible with ImageMagick and ensures that you have installed the latest security updates. To update your system, open the terminal and run the following command.

sudo apt update && sudo apt upgrade

Install Required Libraries

To ensure the correct functioning of ImageMagick, several libraries must be installed. To install these libraries, execute the following command.

sudo apt install libpng-dev libjpeg-dev libtiff-dev

Method 1: Install ImageMagick with APT

For the average user, using the APT package manager is the easiest and most recommended method to install ImageMagick. If this method works correctly, it is advisable to stick with it and avoid installing ImageMagick via the source method. The latter can be more complicated than necessary and may result in additional problems.

To install ImageMagick using the APT method, use the following command.

sudo apt install imagemagick

And that’s it! The following section will cover how to compile ImageMagick if you are looking for alternative installation methods.

Method 2: Install ImageMagick with Source

If you prefer an alternative installation method, you can opt for cloning the ImageMagick GIT repository and compiling the application. However, this method is more advanced and may not be suitable for the average user. 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.

git --version

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:

cd ImageMagick

Alternatively, if you cloned the repository to “/usr/local/src/ImageMagick,” you can navigate to the directory by running the following command:

cd /usr/local/src/ImageMagick

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.

./configure

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.

./configure --with-modules

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.

make

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:

Example only:

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:

magick --version

Example output:

Version: ImageMagick 7.1.0-62 (Beta) Q16-HDRI x86_64
