When I try to run the following command
pecl install imagick
Then the installation end up with:
imagemagick/7.0.11-9/lib -L/usr/local/Cellar/imagemagick/7.0.11-9/lib -lMagickWand-7.Q16HDRI -lMagickCore-7.Q16HDRI

The reason seems to be that the compilation of the last version of imagick (3.5.0) has changes that require this library. It's impossible to install a lower version because they are not compatible with PHP 8.0.
Any idea how to get rid of this error on macos?
As of 22 July 2021, version 3.5.1 is stable in the pecl channel and can be used to compile imagick for both PHP 7 and PHP 8.
pecl install imagick
The general command will not fail anymore
Version 3.5 currently can't compile on MAC because of missing/broken support for gomp of the MAC gcc compiler.
Best fix is to install version 3.4.4
pecl install imagick-3.4.4
More info here
There is a fix for this issue by manually installing the extension. The only issue with it is that it does not appear in the pecl installed extensions after the installation is done and can't be uninstalled from pecl. Nonetheless I'm providing the answer I found here:
Run the following commands
cd path/to/installation/is/going/to/be/made
pecl bundle imagick
cd imagick
mv config.m4 config.m4.bak
wget https://raw.githubusercontent.com/yyongpil/imagick/2a2b924b9d25c8ef4a677b72e6868fbc7c9e01cc/config.m4
To explain the previous process command line by command line:
config.m4 file for safety purposesconfig.m4 file to fix gomp issue as explained hereAnd finally simply continue with the manual installation process
phpize
./configuration
make
sudo make install
After this, you should be good to go to use the latest imagick extension for PHP. For PHP 8.0 and imagick 3.5.0 the so file is located at /usr/local/lib/php/pecl/20200930/imagick.so
A new version has been tag and contains the build configuration fixed! You can install it with this command:
pecl install imagick-3.5.1
(without the version it should now work)
