[Nagiosplug-devel] Problems with check_procs and pst3 in Solaris 9

[Anders Nordby]

Hi,

If I build pst3 straight without anything special, it gives me this
error:

# ./plugins-root/pst3: /dev/ksyms is not a 32-bit kernel namelist
pst3: Failed to open kernel memory: Error 0

To get the pst3 program getting further, I had to compile it as a 64-bit
binary (and since I was doing that, I did that to the whole plugin
package):

# CFLAGS="-g -O2 -m64" STRIP="" ./configure --without-gnu-ld
# make

But the pst3 program crashes. When I try to run it manually through gdb
(a 64-bit version of gdb 6.0), I get:

# /root/gdb-6.0/gdb/gdb ./pst3

The program is running.  Exit anyway? (y or n) y

I am using nagios-plugins-1.4.4.tar.gz and
nagios-plugins-HEAD-200610300052.tar.gz (the gdb run above is done with
the snapshot).

This problem does not exist in Solaris 8.

Also I suggest someone add hints about using --without-gnu-ld and adding
/usr/ccs/bin to PATH in Solaris, as nagios-plugins does not build easily
without it.

Let me know if anyone can figure out a fix before I do. Just want it
fixed.

Bye,
