questions about Makefile

[Martin Waschbüsch]

Hi all,

I am in the process of creating a port for a module / plugin for net-mgmt/zabbix-agent.

I tried to follow the Porter's Handbook, but still have three items I am uncertain about:

1) The plugin (obviously) relies on the zabbix-agent sources.
I added

BUILD_DEPENDS=	${NONEXISTENT}:net-mgmt/zabbix3-agent:extract

to make sure that the sources will always be extracted. Now, how do I properly reference these sources in my port?
What I have right now (just to make it compile) is this:

CONFIGURE_ARGS=	--with-zabbix=${PORTSDIR}/net-mgmt/zabbix3-agent/work/zabbix-3.0.2

Obviously, I'd want to somehow get that path without having to specify the version number as I want to build against the version currently available in ports.
How do I do that? Is there any reference to something like this in the handbook?

2) Imagine this module could be compiled against both, zabbix2-agent and zabbix3-agent. I guess the cleanest way to support this would be having one port per zabbix-version?
If that is the case, should the whole thing perhaps be a slave port belonging to zabbix{2,3}-agent?

3) I found that I cannot (as a normal user) successfully run 'make package'.
I get an error like this:
mkdir: /usr/ports/net-mgmt/foobar/work: Permission denied
Before I add 'NEED_ROOT=yes' to the Makefile, are there requirements for a normal user to build ports? e.g. does said user have to be in a certain group, etc.? I mean, every port will have to create a workdir, and I cannot imagine every port as having 'NEED_ROOT=yes' in their Makefile... ;-)


Any and all help is appreciated!
