First incarnation of our Linux emulator or rather compatibility code. This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work. 1995-06-25 17:32:43 +00:00			`#!/bin/sh`
Load linux emulator lkm only when not already loaded. This avoids leftover files in /tmp. Script slightly modified from PR version to use fewer processes. PR: i386/7725 Submitted by: Stefan Eggers seggers@semyam.dinoco.de 1998-09-07 16:15:59 +00:00
