Hello everyone. I'm trying to compile under Linux a project developed
in Windows environment, but I get some compiler errors with TRect and
TPoint. In particular with:

- TRect.CenterPoint function
- TRect.Width / Height properties
- TPoint <> operator

I read the warnings in typshrdh.inc and also some posts in the forum,
but I did not understand how to solve the problem with Linux. Thanks
in advance for the support.

What is your compiler version? (on windows and linux?)

@simone

As far as I know TRect.Width and TRect.Height are not available on
Lazarus 1.6.0 FPC 3.0.0. But I'm sure it is available on Lazarus
1.6.4. It is time to update your Lazarus/FPC.

I'm using latest stable versions available on both platforms. In my
tests with Linux Ubuntu I used Lazarus 1.6+dfsg-1. I'm developing my
project under Windows with Lazarus 1.6.4.

Well, then that is the problem, like both Handoko and I suspected.
1.6.4 packs FPC 3.0.2 which contains a cleanup of TRect.  1.6 packs
3.0.0 which doesn't.

The easiest solution is to migrate Linux to a newer, FPC 3.0.2 using
version.

Thanks for the help. For laziness, on Linux I haved installed Lazarus
with apt-get. I wrongly thought to get the latest version in this
way...
