I am trying to move a small Windows console program from Delphi2007 on to Lazarus 1.6 with FPC 3.0 on a Raspberry Pi 3.
So I used FTP to copy the project files over to RPi, then used Lazarus on the RPi and tried the tool for converting Delphi projects.

It stops at a point where it cannot find 6 Indy10 units used by the program. And the tool does not find them when searching either. What should I do next?

I do have Indy10 on my RPi in location /home/pi/dev/indy10 and it has been used previously in other projects.
The imported project is located in /home/pi/Projects/TCPCommTest.

I thought that Lazarus would remember the location of any such package once used, but it seems not to be the case...

What do I do now?

Add Indy10 as requirement in the Project / Project Inspector.

It does remember the location of the package.
The Search tool searches only within the .lpk files, not in all unit paths of all packages - that's on my todo list. Maybe Indy10 forgot to list all its units.

Thanks, I added indylaz as requirement and now it finds the files as it should!

But now I am getting a different error message from a non-Indy problem:

I am using the Synopse PasZip unit to add zipping functionality to my program. When I moved it into Lazarus on an RPi3 I get the following error message:

PasZip.pas(60,3) Fatal: Cannot find LibC used by PasZip of the Project
Inspector.

This is the PasZip code that it complains about:

uses
{$ifdef MSWINDOWS}
  Windows,
{$else}
  LibC, <== Error here
  Types,
{$endif}
  SysUtils;

When I google this it seems like there has been some problems earlier with LibC and Lazarus, but I did not find a working solution.

What to do?

LibC was an ancient unit for Linux only. It vanished from FPC many years ago.
Its functions are now in units like Unix, BaseUnix, etc to support more platforms than Linux.

Search the functions in FPC and use the new units.

I switched to using the FPC unit Zipper instead and skip PasZip altogether if FPC is detected (conditional compile). Now working fine.
