Missing predefs.h

[Rodayo]

I'm trying to build the ANSI C port for Unix v6. I'm cloned this git repo, git://pdos.csail.mit.edu/xv6/xv6.git

When I run make I get the following error:

/usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory

Does anyone know what could be causing it and how to fix it?

Found a fix. I needed the proper libc includes for 32-bit builds. I'm running a 64-bit machine. So I just ran:

sudo apt-get install libc6-dev-i386

Thank you! This also worked for me while I was installing OpenACC accelerator tools for PGI on my Ubuntu 12 64 bit machine. I already had my CUDA drivers squared away.
