Summary: pst3 failure on solaris 10 x86

Initial Comment:
https://sourceforge.net/tracker/index.php?func=detail&aid=1476451&group_id=29880&atid=397597

check_procs fails on Solaris 10 x86:

root at infdb4.prodqa.coremetrics.com # ./check_procs -vvv
CMD: /usr/local/nagios_new/libexec/pst3
CRITICAL - Plugin timed out after 10 seconds

truss shows this just spinning through a read, finding
nothing, then eventually trapping a SIGALRM.

Onward!

root at infdb4.prodqa.coremetrics.com #
/usr/local/nagios_new/libexec/pst3
/usr/local/nagios_new/libexec/pst3: /dev/ksyms is not a
32-bit kernel namelist
pst3: Failed to open kernel memory: Error 0

It appears we're using a 32-bit version of libkvm. I
assume the generic /usr/lib/libkvm.so is a 32-bit
version while /usr/lib/amd64/libkvm.so is 64-bit. At
least the ELF class for libkvm.so is 64-bit.

I can't seem to find the write linking magic to make
this work.

Hi!

Can you please try the snapshot at http://nagiosplug.sf.net/snapshot. The
ps command has changed from pst3 to /usr/ucb/ps for Solaris.

I've marked this call in pending. Please update if there is still a
problem.

Update to my previous comment: you must compile all the
plugins in their entirety as 32 bit or 64 bit, and the
supporting libraries must match, due to the
interdependencies between object files. For Solaris, this
effectively means 64 bit throughout only. The alternative is
to bodge config.h to use the builtin ps command instead.

pst3 needs to be compiled to match the Solaris kernel in
use, either 32 bit or 64 bit (usually the latter on recent
SPARC hardware). For the Sun Studio compiler, add -xarch=v9a
to the CFLAGS. For GCC, add -m64. However, this may not be
correct for other plugins since it depends what bit size the
supporting libraries were compiled for (e.g. compiling in 64
bit mode against a 32 bit OpenSSL library won't work). I'd
suggest adding the extra parameters only to CFLAGS in
plugin-root/Makefile.

This looks like something that needs detecting at configure
time.

This problem also occurs on Solaris 10 (06/06) sparc
