|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
module allows
|
||||
.Nx Ns Tn /sparc64
|
||||
to run
|
||||
.Nx Ns Tn /sparc
|
||||
executables.
|
||||
.Pp
|
||||
To use
|
||||
.Nm "" ,
|
||||
one must either have
|
||||
.Dv COMPAT_NETBSD32
|
||||
in the kernel, or load the compat_netbsd32 and exec_netbsd32 kernel
|
||||
modules.
|
||||
.Pp
|
||||
Static executables typically need no additional setup.
|
||||
Dynamic binaries require the dynamic linker, plus shared libaries. Most of
|
||||
these files will need to be placed under
|
||||
.Pa /emul/netbsd32 .
|
||||
.Pp
|
||||
The easiest method of installing support for these is via the
|
||||
.Pa emulators/netbsd32_compat14
|
||||
and
|
||||
.Pa emulators/netbsd32_compat15
|
||||
packages, provided in the
|
||||
.Nx
|
||||
packages collection. These install 32-bit a.out and ELF compatibility
|
||||
libraries, respectively. The details of what is actually necessary for
|
||||
correct operation are given below. This obviously is handled by the
|
||||
emulator packages.
|
||||
.Pp
|
||||
For a.out compatibility,
|
||||
.Pa /usr/libexec/ld.so
|
||||
from a 32-bit distribution is required to exist as
|
||||
.Pa /emul/netbsd32/usr/libexec/ld.so .
|
||||
For 32-bit ELF compatibility,
|
||||
.Pa /usr/libexec/ld.elf_so
|
||||
needs to be in
|
||||
.Pa /emul/netbsd32/usr/libexec/ld.elf_so .
|
||||
.Pp
|
||||
The shared libaries for a.out binaries do not live under the
|
||||
.Pa /emul/netbsd32
|
||||
directory, but under the
|
||||
.Pa /emul/aout
|
||||
directory, where the a.out dyanmic linker will find them.
|
||||
.Pp
|
||||
.Sh BUGS
|
||||
A list of things which fail to work in compatibility mode should
|
||||
be here.
|
||||
.Pp
|
||||
IPC is not well supported.
|
||||
.Pp

||||
