Failed to compile custom language module for PHP 5.2.17 with Unit 1.30

[ylighgh]

Why did I fail to compile the PHP 5.2.17 language module on my computer and what can I do to resolve it?

Wow, PHP 5.2 is really old!

What system is that, that still has such an old PHP?

We do still support 5.4, not sure if 5.3 works or not.

[rwahowa]

Can't you use a newer version of PHP? If your application requires 5.2 then it is probably an abandoned project, making it a no-go zone.

Yes, this version of PHP is really old and I am currently planning to upgrade it to PHP8.0
