Subject: [naemon-dev] successfully compiled naemon on AIX7.2
Message-ID: <D64E4C3B-5232-46FC-B772-A412E8B76597@x-byte.ch>

Hi,

naemon on linux works great, thanks for all that.
we are running some AIX hosts so we compiled naemon for AIX.
it took a long time and hard debugging until we got it running on AIX without dumping all the time.
i want to give back our findings to the community.

i hope you will check the patches and let it be integrated, so other can run naemon on AIX?

Using Prereqs:
 
gcc-8.1.0-2.ppc
m4-1.4.17-1.ppc
automake-1.16.1-1.noarch
 
Compile NAEMON on AIX7.2 (naemon-core version 1.1.0)
