When trying to install ZeosDBO (7.1.4) on Lazarus 1.6.4 it give me a
whole load of messages I have no idea what to do about. Can anybody
assist? I am new to Lazarus.

I had a similar problem a few months ago. I was told to do "Run" ->
"Clean up and Build". It takes a while to rebuild everything but it
cleared up my problems. Good luck!

Thank you, I will give it a try.

At a glance, I would say that the messages this time a more to do with
the application itself, possibly because you are using functions that
give rise to warnings about potential cross platform issues.

For example, the lazfileutils.inc(387,18) Warning: Symbol "faSysFile"
is not portable message has arisen because you are using Windows only
file attributes. Depending on your intended audience, this may not be
a problem.

Similarly, where you are getting deprecated this shows that you are
using constructs that although they may work at the moment, are
intended for withdrawal in later versions of the compiler. 

For example, you are getting the warning Warning: Symbol "Handle" is
deprecated: "use Reference.Handle instead". In this case, I would
recommend trusting that the compiler knows what it is talking about,
and to use Reference.Handle rather than Handle.

I reckon, that with a bit of careful cleaning up of your source code,
you should be able to get rid of all of those messages. On the plus
side, your application has actually compiled! The compiler is just
warning you of potential future problems.

It's also worth pointing out that if you look in Project Options ->
Compiler Options -> Verbosity you can control how strict the reporting
of the compiler actually is. it's then a case of striking a balance
between having a nice "clean" compilation, which may feel
superficially good, against the deeper satisfaction of actually
weeding out those problems and getting a genuinely clean build. As you
get more experienced, you will undoubtedly lean towards the latter
approach.
