Today I’m using Laravel to prototype an application.
I have to manage a lot of PHP versions at the same time that’s why I’m using phpbrew which is an awesome piece of software btw.

I compiled recently PHP 7.2.9 and forgot to add the GD library to it.

With phpbrew you can add GD library afterwards with the following command:

phpbrew ext install gd

This command is handy as you don’t need to recompile PHP entirely

It usually works fine but I got this error:

Error: Command failed: phpize

After some researches it seems I had some packages missing:

sudo apt-get install autoconf automake libtool m4

I ran the command to install the packages and install gd again.

$ phpbrew ext install gd
===> Installing gd extension...

And that’s it!
