Installing Imagick extension with WebP support

MX-19.4

I succeeded by simply doing the following after installing imagemagick, libwebp and libwebp-dev:

sudo apt install php-imagick
sudo service apache2 restart

Ubuntu 16.04

In order to get imagick with WebP on Ubuntu 16.04, you (currently) need to:

1. Compile libwebp from source
2. Compile imagemagick from source (./configure --with-webp=yes)
3. Compile php-imagick from source, phpize it and add extension=/path/to/imagick.so to php.ini

Ubuntu 18.04 (from source)

A simple sudo apt-get install php-imagick unfortunately does not give you webp support. Again, you must:

1. Compile libwebp from source

Instructions are here. In short, you need to:

sudo apt-get install libjpeg-dev libpng-dev
wget https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-1.1.0.tar.gz
tar xvzf libwebp-1.1.0.tar.gz
cd into the dir
./configure
make
sudo make install

2. Compile imagemagick from source, configured with webp

See tutorial here, but configure with webp (./configure --with-webp=yes)

sudo apt-get update
sudo apt build-dep imagemagick
wget https://imagemagick.org/download/ImageMagick.tar.gz
tar xvzf ImageMagick.tar.gz
cd into the dir
./configure --with-webp=yes
sudo make
sudo make install
sudo ldconfig /usr/local/lib
sudo identify -version   # to check if installed ok
make check  # optional run in-depth check

Check it this way: identify -list format | grep WEBP

• It should print a line

3a. Install extension with pecl

First find out which version of PHP you are using and the location of the relevant php.ini file. Both of these can be obtained with phpinfo();. Next do the following (but alter to use the info you just collected):

sudo apt-get update
sudo apt-get install imagemagick gcc libmagickwand-dev php-pear php7.2-dev
sudo pecl install imagick
sudo echo "extension=imagick.so" >> /etc/php/7.2/apache2/php.ini
sudo service apache2 restart

3b. Alternively to using pecl, compile php-imagick from source

https://github.com/mkoppanen/imagick First find out which version of PHP you are using and the location of the relevant php.ini file. Both of these can be obtained with phpinfo();. Next do the following (but alter to use the info you just collected):

wget https://pecl.php.net/get/imagick-3.4.3.tgz
tar xvzf imagick-3.4.3.tgz
cd into the dir
sudo /usr/bin/phpize7.2      # note: find you version of phpize with locate phpize
./configure
make
make install
sudo echo "extension=imagick.so" >> /etc/php/7.2/apache2/php.ini
sudo service apache2 restart
