.Os
.Sh NAME
.Nm compat_sunos
.Nd setup for running SunOS binaries under emulation
.Sh DESCRIPTION
OpenBSD/sparc and some of the OpenBSD/m68k architectures can run
SunOS executables.
Most executables will work.
.Pp
The SunOS compatibility feature is active
for kernels compiled with the
.Nm COMPAT_SUNOS
option and kern.emul.sunos
.Xr sysctl 8
enabled.
.Pp
Compatibility with SunOS version 5 and later, better known as Solaris,
is
.Em not
addressed by these instructions; please read the
.Xr compat_svr4 8
manual page instead.
.Pp
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.
.Pp
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.
.Pp
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
.Ox
machine, do the following:
.Pp
.Bl -enum -offset 123 -compact
.It
.Li mkdir -p /emul/sunos/usr/lib /emul/sunos/usr/5lib
.fi
.Pp
.It
.Li cp SunOS:/usr/lib/lib*.so.*.* OpenBSD:/emul/sunos/usr/lib
.Pp
.It
.Li cp SunOS:/usr/5lib/lib*.so.*.* OpenBSD:/emul/sunos/usr/5lib
.Pp
.It
.Li cp SunOS:/usr/lib/ld.so OpenBSD:/emul/sunos/usr/lib/ld.so
.Pp
.It
If YP is going to be used, create a link:
.nf
.Li ln -s /var/run/ypbind.lock /etc/ypbind.lock
.fi
.El
.Pp
Alternatively, an NFS mount can accomplish the same
effect.
On the
.Ox
machine, do the following:
.Pp
.Bl -enum -offset 123 -compact
.Pp
.It
.Li mkdir -p /emul/sunos/usr
.Pp
.It
.Li mount SunOS:/usr /emul/sunos/usr
.fi
.El
.Pp
This will place the SunOS libraries on the
.Ox
machine in a location where the SunOS compatibility code will look
first, in order to avoid conflict with the standard libraries.
