.Os
|
|
.Sh NAME
|
|
.Nm compat_sunos
|
|
.Nd setup procedure for m68k, sparc and sparc64 architectures
|
|
.Sh DESCRIPTION
|
|
.Nx Ns Tn /sparc64 ,
|
|
.Nx Ns Tn /sparc
|
|
and some of the
|
|
.Nx Ns Tn /m68k
|
|
architectures can run
|
|
.Tn SunOS
|
|
executables. Most executables will work.
|
|
.Pp
|
|
The exceptions include programs that use the
|
|
.Tn SunOS
|
|
kvm library,
|
|
and various system calls,
|
|
.Fn ioctl Ns '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 you need are on your
|
|
.Tn SunOS
|
|
machine.
|
|
You need to worry about the legal issues of ensuring that you
|
|
have a right to use the required files on your machine.
|
|
On your
|
|
.Nx
|
|
machine, do the following:
|
|
.Bl -enum -offset 123
|
|
.It
|
|
.Li mkdir -p /emul/sunos/usr/lib /emul/sunos/usr/5lib
|
|
.It
|
|
.Li cp SunOS:/usr/lib/lib*.so.*.* NetBSD:/emul/sunos/usr/lib
|
|
.It
|
|
.Li cp SunOS:/usr/5lib/lib*.so.*.* NetBSD:/emul/sunos/usr/5lib
|
|
.It
|
|
.Li cp SunOS:/usr/lib/ld.so NetBSD:/emul/sunos/usr/lib/ld.so
|
|
.It
|
|
If you ever expect to use YP, you will want to create a link:
|
|
.Bd -literal -compact
|
|
ln -s /var/run/ypbind.lock /etc/ypbind.lock
|
|
.Ed
|
|
.El
|
|
.Pp
|
|
Alternatively, you can use an NFS mount to accomplish the same
|
|
effect.
|
|
On your
|
|
.Nx
|
|
machine, do the following:
|
|
.Bl -enum -offset 123
|
|
.It
|
|
.Li mkdir -p /emul/sunos/usr
|
|
.It
|
|
.Li mount SunOS:/usr /emul/sunos/usr
|
|
.El
|
|
.Pp
|
|
This will place the
|
|
.Tn SunOS
|
|
libraries on your
|
|
.Nx
|
|
machine
|
|
in a location where the
|
|
.Tn SunOS
|
|
compatibility code will look for
|
|
first, where they do not conflict with the standard libraries.
|
|
.Sh NOTES
|
|
When using
|
|
.Nm
|
|
on
|
|
.Nx Ns Tn /sparc64 ,
|
|
the
|
|
.Dv COMPAT_NETBSD32
|
|
option must also be used.
|
|
.Sh BUGS
|
|
A list of things which fail to work in compatibility mode should
|
|
be here.
|
|
.Pp
|
|
.Tn SunOS
|
|
executables can not handle directory offset cookies \*[Gt] 32 bits.
|
|
Should such an offset occur, you will see the message
|
|
.Dq sunos_getdents: dir offset too large for emulated program .
|
|
Currently, this can only
|
|
happen on NFS mounted filesystems, mounted from servers that return
|
|
offsets with information in the upper 32 bits. These errors should
|
|
rarely happen, but can be avoided by mounting this filesystem with offset
|
|
translation enabled. See the
|
|
.Fl X
|
|
option to
|
|
.Xr mount_nfs 8 .
|
|
The
|
|
.Fl 2
|
|
option to
|
|
.Xr mount_nfs 8
|
|
will also have the desired effect, but is less preferable.
|
|
.Pp
|
|
The
|
|
.Nx Ns Tn /sparc64
|
|
support is less complete than the other ports.
