Yaroslav Tykhiy 822923447e Let modules use the kernel's opt_.h files if built along with the kernel by wrapping all targets for fake opt_.h files in .if defined(KERNBUILDDIR). Thus, such fake files won't be created at all if modules are built with the kernel. Some modules undergo cleanup like removing unused or unneeded options or .h files, without which they wouldn't build this way or the other.

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).
