143415SnewtonThis is a SysVR4 emulator derived from work done as part of the NetBSD 243415SnewtonProject by Christos Zoulas. It has been ported to FreeBSD by Mark Newton. 343415Snewton 443415SnewtonTo use it: 543415Snewton 649268Snewton1. Choose one of: 776185Sschweikh a. Add "device streams" to your kernel config file and rebuild, 849268Snewton reboot; or 949268Snewton b. Build and install the streams module in /sys/modules/streams 1043415Snewton 1143415Snewton2. Build and install the svr4 module in /sys/modules/svr4 1243415Snewton 1369349Ssheldonh3. Type "kldload svr4" to start it up. 1443415Snewton 1543415Snewton4. Grab compat_sol26.tar.gz or compat_svr4.tar.gz from 1643415Snewton http://www.freebsd.org/~newton/freebsd-svr4 and install them in 1743415Snewton /compat/svr4 1843415Snewton 1943415Snewton5. Run "sh SVR4_MAKEDEV all" in /compat/svr4/dev 2043415Snewton 2149268Snewton6. Mount a Solaris/x86 v2.6 or v7 CD-ROM on /cdrom (also works with 2249268Snewton v2.4 and v2.5.1, but you need different symlinks in /compat/svr4) 2343415Snewton 2449268Snewton7. Brand any executables you want to run, and/or set the 2549268Snewton kern.fallback_elf_brand sysctl to 'SVR4' to establish this as the 2649268Snewton default emulator for unbranded executables. 2743415Snewton 2849268Snewton8. See if your SysVR4 programs work. 2943415Snewton 3043415SnewtonIt's early days yet, folks -- You'll probably have trouble getting 100% 3143415Snewtonfunctionality out of most things (specifically, poll() on a socket doesn't 3243415Snewtonlook like it works at the moment, so Netscape doesn't work (among other 33267734Sgavinthings)). Patches will be appreciated. 3443415Snewton 3549268Snewton - Mark Newton 3643415Snewton newton@atdot.dotat.org 3743415Snewton 3850477Speter$FreeBSD$ 39
