I Can't figure out how to install php-gd for PHP7.2.11. Is there any way to install/enable GD extension in xampp Ubuntu 18.04? I checked the php.ini file but I can't find php_gd2.so line.Any suggestions??
Under Linux you have ".so" files. You can install it very easy over the package manager. Check before if the package is installed:
dpkg -l|grep php7.2-gd
If not then install it via apt.
apt install php7.2-gd
If you have an oder version then use apt-get install. It is possible that this package is used and installed by default that is thy you should check, if it's already installed.
