hi all,
i come from windows and delphi , i installed lazarus 0.9.31 + fpc
2.4.2 on a mac os snowleopard 10.6.3 .
i did a very simple application , a form with a hello and i have a
'error while linking' error when i try to build the application .
in the message box i see some messages but at the end remain only one
row with the 'error while linking' message.
i really don't know how to solve it.
Thanks in advance
Beppe

Did you install Xcode? That's where the linker and other tools that
FPC needs come from.

You can Ctrl+Click (right-click) in the message box and copy all
messages, including any hidden ones, to the clipboard. Then you can
paste them into a text editor. That may provide more information.

Thanks.

Take a look at this earlier exchange with a similar problem. It looks
like maybe you need to update your Xcode or something. What version of
Xcode do you have installed? Is it from your Leopard (10.5) DVD?

Click Next Page at the bottom to see more.

Thanks.
