Install Imagick 3.4.3 on PHP 7.1 server (Laravel Forge)

imagick3.4.3-PHP7.1-forge.sh

#!/bin/bash
if [ "$EUID" -ne 0 ]
  then echo "Please run as root"
  exit
fi

apt-get install pkg-config libmagickwand-dev -y
cd /tmp
wget https://pecl.php.net/get/imagick-3.4.3.tgz
tar xvzf imagick-3.4.3.tgz
cd imagick-3.4.3
phpize
./configure
make install
rm -rf /tmp/imagick-3.4.3*
echo extension=imagick.so >> /etc/php/7.1/cli/php.ini
echo extension=imagick.so >> /etc/php/7.1/fpm/php.ini
service php7.1-fpm restart
service nginx restart

I get the following when running this:

`----------------------------------------------------------------------
Libraries have been installed in:
   /tmp/imagick-3.4.3/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

RE:

getcwd gets the current working directory and if the directory is deleted or moved it will be unhappy!

@NickJorens, I get the same error and imagick does not work. Were you able to figure out what was wrong?

I also get the following error when I run php -v: PHP Warning: Module 'imagick' already loaded in Unknown on line 0

--Update. Once I restarted the server everything was working. Not sure why or how, but try rebooting if you are having this problem.

@drfraker, you might have the extension also enabled in /etc/php/7.1/mods-available/imagick.ini
restarting the php and nginx services didn't work for me either, like you i restarted the server and imagick started working
for phpize i had to sudo apt install php7.1-dev

THANKS :)
