    Missing predefs.h

    I'm trying to build the ANSI C port for Unix v6. I'm cloned this git repo, 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
