|

.Os
|
|
.Sh NAME
|
|
.Nm compat_osf1
|
|
.Nd setup procedure for running OSF/1 binaries
|
|
.Sh DESCRIPTION
|
|
.Nx
|
|
supports running OSF/1 (a.k.a Digital Unix, a.k.a. Tru64) binaries on
|
|
.Nx Ns Tn /alpha
|
|
systems.
|
|
Most programs should work, including the ones that use the shared object
|
|
libraries.
|
|
Programs that make direct MACH system calls will not work.
|
|
The OSF/1 compatibility feature is active for kernels compiled with the
|
|
.Dv COMPAT_OSF1
|
|
option enabled (see
|
|
.Xr options 4 ) .
|
|
.Pp
|
|
To run dynamically linked programs, you will need the OSF/1 shared libraries,
|
|
runtime linker, and certain configuration files found in /etc.
|
|
These are installed in a
|
|
.Dq shadow root
|
|
directory called
|
|
.Pa /emul/osf1 .
|
|
Any file operations done by OSF/1 programs run under
|
|
.Nx
|
|
will look in this directory first, and fall back to the file system proper.
|
|
So, if an OSF/1 program opens
|
|
.Pa /etc/svc.conf ,
|
|
.Nx
|
|
will first try to open
|
|
.Pa /emul/osf1/etc/svc.conf ,
|
|
and if that file does not exist it will then try
|
|
.Pa /etc/svc.conf .
|
|
Shared libraries and configuration specific to OSF/1 should be installed
|
|
in the shadow tree.
|
|
.Ss Setting up /emul/osf1
|
|
The simple technique is to install pkgsrc/emulators/osf1_lib.
|
|
(You may
|
|
also want to install pkgsrc/www/navigator and/or pkgsrc/www/communicator.)
|
|
.Pp
|
|
Alternatively, if you have access to an OSF/1 machine and if the licensing
|
|
details permit, you can copy the contents of:
|
|
.Bl -item -compact -offset indent
|
|
.It
|
|
.Pa /shlib
|
|
.It
|
|
.Pa /usr/shlib
|
|
.It
|
|
.Pa /etc/sia
|
|
.It
|
|
.Pa /usr/lib/X11/locale
|
|
.El
|
|
.Pp
|
|
(The latter is required to run Netscape Navigator or Communicator.)
|
|
.Pp
|
|
Also copy
|
|
.Bl -item -compact -offset indent
|
|
.It
|
|
.Pa /etc/svc.conf
|
|
.It
|
|
.Pa /usr/ccs/lib/cmplrs/otabase/libots.so
|
|
.It
|
|
.Pa /sbin/loader
|
|
.El
|
|
.Pp
|
|
Or, simply NFS mount the appropriate directories under
|
|
.Pa /emul/osf1 .
|
|
.Sh SEE ALSO
|
|
.Xr config 1 ,
|
|
.Xr options 4
|
|
.Sh BUGS
|
|
Your
|
|
.Xr hostname 1
|
|
.Em must
|
|
contain a dot
|
|
.Em or
|
|
your
|
|
.Xr resolv.conf 5
|
|
must contain a
|
|
.Li search
|
|
line.
|
|
Without one of those, the OSF/1 resolver will die and no hostname
|
|
resolution will be possible.
|
|
.Pp
|
|
Certain values in
|
|
.Pa /emul/osf1/etc/svc.conf
|
|
can cause programs to fail with
|
|
.Dq Bad system call .
|
|
.Pp
|
|
Pathnames pointed to by symbolic links are not looked up in the
|
|
shadow root when running an OSF/1 executable.
|
|
This is not consistent.
