     compat_sunos - setup for running SunOS binaries under emulation

DESCRIPTION    [Toc]    [Back]

     OpenBSD/sparc and some of the OpenBSD/m68k architectures can
run SunOS
     executables.  Most executables will work.

     The SunOS compatibility feature is active for  kernels  compiled with the
     COMPAT_SUNOS option and kern.emul.sunos sysctl(8) enabled.

     Compatibility  with  SunOS version 5 and later, better known
as Solaris, is
     not addressed by these instructions; please  read  the  compat_svr4(8) manual
 page instead.

     The  exceptions  include programs that use the SunOS kvm library, and various
 system calls, ioctl()'s, or kernel  semantics  that  are
difficult to
     emulate.   The number of reasons why a program might fail to
work is
     (thankfully) longer than the number of programs that fail to
run.

     Static  executables will normally run without any extra setup.  This procedure
 details the directories and files that must be set up
to allow dynamically
 linked executables to work.

     The files needed can be found on the SunOS machine.  The user is responsible
 for the legal issues of  ensuring  that  they  have  a
right to use the
     required files on their machine.  On the OpenBSD machine, do
the following:


        1.   mkdir -p /emul/sunos/usr/lib /emul/sunos/usr/5lib

        2.        cp      SunOS:/usr/lib/lib*.so.*.*       OpenBSD:/emul/sunos/usr/lib

        3.        cp      SunOS:/usr/5lib/lib*.so.*.*      OpenBSD:/emul/sunos/usr/5lib

        4.          cp        SunOS:/usr/lib/ld.so         OpenBSD:/emul/sunos/usr/lib/ld.so

        5.   If YP is going to be used, create a link:
             ln -s /var/run/ypbind.lock /etc/ypbind.lock

     Alternatively,  an NFS mount can accomplish the same effect.
On the
     OpenBSD machine, do the following:

        1.   mkdir -p /emul/sunos/usr

        2.   mount SunOS:/usr /emul/sunos/usr

     This will place the SunOS libraries on the  OpenBSD  machine
in a location
     where the SunOS compatibility code will look first, in order
to avoid
     conflict with the standard libraries.

     A list of things which fail to work  in  compatibility  mode
should be here.
