This is a SysVR4 emulator derived from work done as part of the NetBSD
Project by Christos Zoulas. It has been ported to FreeBSD by Mark Newton.
To use it:
1. Choose one of:
a. Add "device streams" to your kernel config file and rebuild,
reboot; or
b. Build and install the streams module in /sys/modules/streams
2. Build and install the svr4 module in /sys/modules/svr4
3. Type "kldload svr4" to start it up.
4. Grab compat_sol26.tar.gz or compat_svr4.tar.gz from
http://www.freebsd.org/~newton/freebsd-svr4 and install them in
/compat/svr4
5. Run "sh SVR4_MAKEDEV all" in /compat/svr4/dev
6. Mount a Solaris/x86 v2.6 or v7 CD-ROM on /cdrom (also works with
v2.4 and v2.5.1, but you need different symlinks in /compat/svr4)
7. Brand any executables you want to run, and/or set the
kern.fallback_elf_brand sysctl to 'SVR4' to establish this as the
default emulator for unbranded executables.
8. See if your SysVR4 programs work.
It's early days yet, folks -- You'll probably have trouble getting 100%
functionality out of most things (specifically, poll() on a socket doesn't
look like it works at the moment, so Netscape doesn't work (among other
things)). Patches will be appreciated (use send-pr).
