[Nagiosplug-help] Compile problem with Nagios-Plugins 1.4.2 onAIX

[Jacob Laack]

All-
I was compiling nagios-plugins-1.4.2 on AIX 5.1 ML9 with GNU gcc 3.3.2 and GNU make 3.80 found on this page http://www-03.ibm.com/servers/aix/products/aixos/linux/download.html  It turns out the floor function is used twice in the 1.4.2 version of check_swap.c but not in version 1.4.  After replacing all uses of "floor(x)" with "(double)(int)(x)", the check_swap plugin, along with the rest of them, compiled just fine.  There may be an incompatibility with AIX's linker and the floor function but anyone with more knowledge of compiling on AIX could probably tell us why.  However, the new check_swap plugin works just great!

Andreas-
It turns out practically everything you said was incorrect as well as mean spirited.  If you fully read my replies rather than harping on the few words you did bother to glimse, you'd see that I did try your tips both at the command line and inside the makefile with the same results.  However, if you had simply done "gcc --help" you'd see that one would have to pass "-bnoquiet", as well as all linker arguments, to gcc with the -Xlinker argument.

I wanted to thank you for the fragments of information I did get from your replies, however, your use of criticism, rudeness, and impatience have made this mailing list a hostile place to try to get information.  If you have knowledge that might benefit someone, please share it.  However, if all you have are scathing remarks that will make people feel foolish whiile building up your own self-image, please keep them to yourself.  You'll do yourself and the rest of the Nagios community a favor.

-Jake

So put it at the start of the command line then...

.. and you forgot '-lmath', and you didn't edit the Makefile, you passed 
it from command-line (which I'm not sure AIX Make handles properly) ...

> gcc  -g -O2  -L. -o check_swap -bloadmap check_swap.o utils.o ../lib/libnagiosplug.a ../lib/libcoreutils.a popen.o ../intl/libintl.a -liconv

... meaning you should run

gcc -bloadmap -bnoquiet -L. check_swap.o utils.o ../lib/libnagiosplug.a 
../lib/libcoreutils.a popen.o ../intl/libintl.a -liconv -lmath

Could be, except that it builds just fine on just about all other unix 
systems. More likely there's either a bug in your linker, or you have 
non-standard libraries installed.

OTOH, you haven't, so far, tried a single thing I suggested, but rather 
a subset of it or in a manner different from what I asked you to do. If 
you want to try something different, then fine, but don't ask me why it 
doesn't work when you do, and don't ask me to provide more things to try 
that you can ignore.
