error running 32 bit app on 64 bit OS

[Kim Kendall]

Just built a new 11.11 system.

Installed the latest version of lsof, but when I try to run it, I get the error:

#./lsof
lsof: WARNING: compiled for HP-UX release B.11.00; this is B.11.11.
lsof: FATAL: lsof was built for a 32 bit kernel, but this
is a 64 bit kernel.

Any idea why it wont run a 32 bit app? I understand that the 64 bit OS is "supposed" to be backward compatible.

That is because probably lsof was built on a PA 1.1 and not a PA 2.0 32 bit system and compiled with 32 bit options.

Here is a thread that is exactly your question.

lsof is a VERY big exception to 32bit app compatibility. The reason is that lsof needs deeply imbedded structures and highly unique values in the kernel to track down all the special files (including directories, network sockets, NFS, etc). Think of lsof as a kernel process. 64bit HP-UX handles internal values differently between 64bit and 32bit. lsof did not originally work on 64bit HP-UX due to all the changes, and early versions that did work required compiling/linking on the actual opsystem--lsof 64bits was not always portable between 64bit systems.

hi,

i got mine working on a 64-bit machine running HP-UX 11.11. However, i install the one meant for 11.00 but it works like a charm:

http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.70/

# gunzip -d /tmp/lsof-4.70-sd-11.00.depot.gz
# swinstall -s /tmp/lsof-4.70-sd-11.00.depot

regards.

FYI - I downloaded the source and compiled my own. I have a working binary now. Thx.

P.S. to Joseph... I could install it, too. But it wouldn't run.
