Compiling Zabbix against MAMPStack

Greetings.

I successfully compiled Zabbix (www.zabbix.com) against MAPPStack. However, when I try to run it, it fails to find a dynamic library for PostgreSQL.

Mostly following the directions at http://lukecyca.com/2008/09/21/howto-install-zabbix-16-on-mac-os-x-105/ (although I am building it on Tiger Server), I configured it thusly:

cd ~/Downloads/zabbix-1.6.4/
env LIBS=”-lresolv” ./configure—enable-server—with-pgsql=/Applications/mappstack-1.1-2/postgresql/bin/pg_config—with-net-snmp—with-libcurl—prefix=/Library/Zabbix
sudo make install

It builds and installs fine. When I try to run it, I get this:

$ /Library/Zabbix/sbin/zabbix_server
dyld: Library not loaded: /bitnami/mappstack/output/postgresql/lib/libpq.5.dylib Referenced from: /Library/Zabbix/sbin/zabbix_server Reason: image not found

I looked through config.log in the zabbix directories, but could find no references to bitnami (although certainly there are references to pg_config).

How do I recompile to avoid this, or otherwise resolve the issue?

Thanks,

Note: I edited the post to use blockquotes, but don’t know how to pre-format the text inside.

Hi, it is not necessary to recompile. The problem is that the “zabbix_server” binary file can not found the postgresql libraries. Try the following:

$ cd /Applications/mappstack-1.1-2
$ ./use_mappstack.sh

Using this script you are loading the environment variables for the Stack. You can check your new environment variables typying:
$ export

Then you can start Zabbix server:

$ /Library/Zabbix/sbin/zabbix_server 

I hope it helps.

Thank you, beltran. I’m afraid that even after setting up the environment in that way, the error is unchanged.

Interesting. I’m looking through config.log again, and it has references to /bitnami/mappstack/output/common/include (and /lib) all over the place. I don’t know if it wasn’t there when I searched before, or if I just missed it somehow. I’m trying to see if I can track down where it came from.

Also, if I put a symlink from the dylib file zabbix is looking for to the real file, it works, but I don’t particularly want to have a deep /bitnami path with only a single symlink in it on my server if I can avoid it. [Edit: It turns out that the bitnami path is only there if you start compiling after running use_mappstack.sh. It is not there otherwise.]

Hi,

The /bitnami folder is the path where we compiled the components. It should be enough defining the environment variables: DYLD_LIBRARY_PATH and others.

I learned that to see the libraries that are linked against, one can use:

otool -L /Library/Zabbix/sbin/zabbix_server

Sure enough, it shows an entry starting with /bitnami.

I did play with DYLD_LIBRARY_PATH (and others). Trying it again, though, it appears to have worked:

DYLD_LIBRARY_PATH=/Applications/mappstack-1.1-2/postgresql/lib/ /Library/Zabbix/sbin/zabbix_server

Interesting. I like that better than a symlink; here is hoping it is the end of my problem.

Yes, that is exactly that I want to explain you but I forget that “use_mampstack.sh” only change the PATH environment.

Try the following. Instead of running “use_mampstack.sh” you can load all environment variables from the “scripts/setenv.sh” file. As you can check this file contains all the environment variables for your Stack.

$ cd <installation_directory>
$ . scripts/setenv.sh (it is important thespace between the dot and the script)
$ export (you can check that environment variables have changed)
$ /Library/Zabbix/sbin/zabbix_server

Of course this is a better solution than a symlink, this is the method that we use to create independent and relocatable Stacks.

Cheers.

That worked nicely! Thank you, beltran.
