SUMMARY:
For normal applications there are always 32 bit compatibility,
Some applications (like lsof) needs to be compiled with a 64 bit complier
(like gcc 3.0) or use a precompiled 64 bit version.
QUOTES:
You've no choice! It'll be compatible for 32 bit applications anyway...
...that is, for applications which aren't intimately involved in the
workings of the kernel. You'll need a 64-bit compiler to compile lsof
in 64-bit mode, or you could just download it precompiled from
sunfreeware.com - Gcc 3.0 has 64-bit capabilities.
maybe you already know this, you can double check if you have turned
compatibility for 32 bits applications on with the command
isainfo -v
To boot into a 32-bit kernel, either set 'boot-file' in the EEPROM to
'kernel/unix' or get to an ok prompt and type 'boot kernel/unix'.
If you are in a hurry you can get the lsof-4.45-64-bit package from
http://sunfreeware.com/
32 bit application compatibility is always on it cannot
be turned off.
Ah, lsof is a "kernel memory browser"; as such, it is on of the applications
that must run in native mode.
You need to recompile lsof with a 64 bit compiler.
lsof is rather a special case because it hooks into the kernel. You'll need
a 64 bit version of the binary to run on a 64 bit kernel. You can download
one from www.sunfreeware.com

Hi All
When I installed Solaris8 in a NetraT1 I'm sure I turned
compatibility for 32 bits applications on. Now I'vwe compiled an
application and returns this message:
-----------------------------------------------------------
# ./lsof -i
lsof: FATAL: lsof was compiled for a 32 bit kernel,
but this machine has booted a 64 bit kernel.

bash-2.03$ isainfo -v
64-bit sparcv9 applications
32-bit sparc applications
bash-2.03$ file lsof
