Building PHP source for Linux / Unix.

Hi,

I am working on porting PHP onto NetWare.

I am a beginner to building PHP source code for Linux / Unix. I am
looking for a document that takes me through a step-by-step guidelines
of doing this. Can someone point me to a link for this?

Also, I am seeing some problems of memory corruption while using XOOPS
application on NetWare, and also it says that functions like
getallheaders are not implemented on NetWare. Since we are using the
same code base as that of Linux / Unix, I am sure why this error
messages are showing up. I would like to understand the Unix build
process to see if the same path is followed on NetWare also. I want to
see if I am missing #define's or whatever.

Help in this is greatly appreciated.

Thanks,
Ananth.
