I'm trying to use imagefttext. And I need to have GD library and/or freetype installed. I'm new to this kind of stuffs, How can I install GD library and freetype in Linux ?
回答1:
Installing GD :
For CentOS / RedHat / Fedora :
sudo yum install php-gd
For Debian/ubuntu :
sudo apt-get install php5-gd
Installing freetype :
For CentOS / RedHat / Fedora :
sudo yum install freetype*
For Debian/ubuntu :
sudo apt-get install freetype*
Don't forget to restart apache after that (if you are using apache):
CentOS / RedHat / Fedora :
sudo /etc/init.d/httpd restart
Or
sudo service httpd restart
Debian/ubuntu :
sudo /etc/init.d/apache2 restart
Or
sudo service apache2 restart

Things are pretty much simpler unless they are made confusing.
To Install GD library in Ubuntu
sudo apt-get install php5-gd
To Install Freetype in Ubuntu

For CentOS: When installing php-gd you need to specify the version. I fixed it by running: sudo yum install php55-gd

Installing freetype:
sudo apt update && sudo apt install freetype2-demos
