AIX 5.3 PPC Agent Compilation Errors

[Thomas Williams]

Hello,

I'm getting errors when trying to compile the latest version of the agent on an AIX 5.3 PPC machine. I'd appreciate any insight. Thanks!

Hi,

oh what a wonder AIX always is

Instead of not finding flock.h it - as it is done on Solaris,
it obviously finds it !
But the library including the flock function is not found.
The missing function flock is in /lib/libbsd.a according to IBM and my researches (IBM AIX 5.3 on PPC).
So, you should include /lib/libbsd.a in the LDFLAGS.
or use my patch . I guess it works on AIX as well as on Solaris and
should not result in any compilation / linking errors. This is because the
lockf function used in my patch is in the standard libc.a (again
according to the same IBM online page).

Edited: You will have to change the "EAGAIN" in my patch to "EACCESS"
to get it really working on AIX. This is mentioned on the online
IBM web page at the end and I didn't read up to there until just now !

BTW: I am very interested in a compiled agent for this platform !
We have some of those systems (real large ones) around, but there
is no compiler installed and those are production systems I don't want to change.

HTH,

Norbert.

Norbert,

Thanks for the advice. After patching pid.c with your patch, it appears to compile successfully. However, when I execute zabbix_agentd, it hangs and uses all available CPU cycles. I've seen similar behavior when compiling for S390. Do you know of a way to get more detailed debug information or do you have any idea what might be happening?

Thanks,

-Thomas

Hi,

try setting the "DebugLevel=5" and increase the size of the logfile
by setting "LogFileSize=50", both in the zabbix_agentd.conf file.

You'll get more info in the logfile /tmp/zabbix_agentd.log

I hope this is not introduced by my patch

HTH,

Norbert.

We fixed compilation under AIX. It was tested under 5.2.

[Thomas Williams]

Excellent! Are the fixes in v1.3.8 or will I need to get the trunk?

[Alexei]

These fixes are in the trunk only.
