Hi, uki!

In ZBX-2015 you described 'configure' step on HP-UX:

# PATH=/usr/local/bin:/usr/local/sbin:/usr/local/ia64/bin/gcc:$PATH CFLAGS=-std=gnu99 ./configure --enable-agent --sysconfdir=/etc/zabbix --localstatedir=/var --with-libpcre2 --with-libpcre2-lib=/usr/local/pcre2-10.42/lib --with-libpcre2-include=/usr/local/pcre2-10.42/include --with-openssl=/usr/local/openssl-1.1.1u CC=/usr/bin/gcc

Can you try it with CFLAGS="-std=gnu99 -Wl,-v" to collect more info from linker?

Thank you for your actions!

I tried build with the options. Output is long, so I attached as "build.log".

Hi, uki!

One problem is failing compilation on HP-UX. But there is another one - currently you are compiling Zabbix agent in 32-bit mode (default). I'm afraid some things would require 64-bit agent. You may want to try adding "-mlp64" to CFLAGS - but that will require PCRE2 and OpenSSL libraries to be 64-bit, too.

But let's try to solve compilation problem first.
The error

ld: Unsatisfied symbol "zbx_get_diskstat" in file ../../src/libs/zbxsysinfo/common/libcommonsysinfo.a[libcommonsysinfo_a-diskdevices.o]

could be caused by the fact that libcommonsysinfo needs "zbx_get_diskstat" from ../../src/libs/zbxsysinfo/hpux/libspecsysinfo.a which is mentioned before libcommonsysinfo on command line and not searched again.
Can you try to repeat linking step with "-(   -) " arguments added to enforce repeated search for unresolved symbols:

Hello Andris,

I tried to use the options but these are unrecognized option in my HP-UX.

Hi, uki!

You can try a fix from development branch  feature/ZBX-23014-6.5.

It works on HP-UX 11.23.

Hello Andris,

I tried the branch. It works fine! Thank you!

Thanks, uki for confirmation that fix works!

The fix was developed by arimdjonoks.

Available in versions:

• pre-6.0.23rc1 8ec4e7d465e
• pre-6.4.8rc1 3420727c379

• pre-7.0.0alpha3 df4499c1e6c

+ additional fix for master (HP-UX with bundled compiler)

• pre-7.0.0alpha7 fbb8506b4b0

Also, available in test-branches for testing:
feature/ZBX-23014-6.4
feature/ZBX-23014-6.0

<andris> Reviewed.

<andris> Updated feature/ZBX-23014-6.0 branch to latest release/6.0, added fixes
b311735a822 and 2726af919be to fix compilation with HP cc (confirmed - the fixes work, agent can be compiled with HP bundled cc compiler on HP-UX 11.23 Itanium, without gcc).

<arimdjonoks> I believe, that instead of adding C99 incompatible fix (which is Zabbix standard), we could instead pass

-AC99

flag to hp-ux compiler
https://flylib.com/books/en/2.872.1.117/1/

andris, was this flag used initially on the customer machine?

<andris> I was not aware of '-AC99', I recommended '-Ae' option, which according to docs is the same:

-AC99
The -AC99 option invokes the compiler in ANSI C99 compilation mode with its features.
This is the default C compilation mode, and the following commands are equivalent:
cc
cc -Ae
cc -AC99
aCC -Ae
aCC -AC99
NOTE: This option will be removed in a future version of the compiler. Use the equivalent option +std=c99 to ensure that your builds do not break in future.

I asked to try with '-AC99'.

<andris> Answer: "AC99" and "Ae" options are not supported by HP-UX bundled cc compiler. Looks like these options require commercial HP compiler - very few users will have it. So, I propose to include fixes workarounds b311735a822 and 2726af919be to allow using a limited HP compiler which is available on every HP-UX.

<arimdjonoks> This is unfortunate, if we cannot require customers to use gcc on hp-ux, then I guess we have no choice, but to resort to this fix. Looks reasonable to me.

<andris> Well, we can propose to use gcc. Problem is limited choice of gcc versions for HP-UX downloadable from internet. Customer pays for turnkey solution, it becomes our problem how to cover old HP-UX versions.

<arimdjonoks> fix will need to be ported to the master branch as well, as the original fix for it was already released,
FIXED in feature/ZBX-23014-6.5-2
