Developing PHP extensions for Linux

[anroy]

Earlier on I started a thread on developing PHP extensions for Windows.

This article was an invaluable help.

I am now creating extensions for Linux. It is extraordinarily difficult because I barely know how to compile programs in Linux. There are a lot of environmental issues, especially to do with paths and libraries.

In the PHP source code download, there is an ext folder containing the source for the various extensions that ship with PHP. Alas, none of them are easy to understand. I am just looking for the "Hello World" example of extension-building.

I do not have time to learn much about gcc or Linux generally, I just need an example that works out of the box and I will just change/add the C code.

Does anyone know where such an example can be found?

Thanks!
