Have you create a package for your AlSortGrid.pas?
Yes I have created a package called 'pat.lpk' and this appears on the Component Palette as 'PAT' with two components installed - alsortgrid' and 'newstringgrid'. However, on compiling an application with them, they do not perform correctly - the grid contains no cells, and when writing to cells, they do not appear.
Has the package as requirement the package LCL?
Yes the package has requirements the packages LCL (>=1.0) and FCL (>=1.0)

The IDE runs with win32 and the installed component are compiled for
win32. Packages can be cross compiled. The created ppu files have
the same name, but are completely incompatible. To avoid name clashes,
the created ppu should be put in different output directories. This is
done by using macros in the unit output directory. Default is:
lib/$(TargetCPU)-$(TargetOS)
I thought this was already in the output path, but on invetstigating again, I find it is not. When I have added it previously, it is found by clicking the (ellipsis?) button to the right of the box. However, on this occasion, clicking the button provides explorer real directories rather than macros. I have put in the macros as suggested and reinstalled for wince, but I get the same error message
"The project uses target OS=Error: illegal parameter; -Twin32 and CPU=Error: illegal parameter; -Twin32,
The system.ppu for this target was not found by the FPC binary directories Make sure fpc is installed correctly for this target and the fpc.cfg contains the right directories."
It then gives a Fatal message saying "Can't find unit Unix used by FileProcs".
I may not have installed Lazarus correctly - I installed the Win32 version first, then the Win32>WinCE version over the top of the first, in the same initial directory of 'lazarus'. Is this correct - I have found no istallation instructions, so assumed it was as described.

You can find it in the package editor of your package / compiler
options / Paths.

Have you tried to reproduce that in a small test program?
Yes, just using the NewStringGrid component which is just a simple descendant of TStringGrid
If yes, you can provide it and I'm sure people will be able to quickly
find out what is going wrong.
It is a NewStringGrid component dropped on the form with a button to put row number in each of 20 cells in a single column. I can attach either the source code, full directory or only the exe file for your inspection. The exe file performs the same in the Windows Mobile 6.5 emulator as the Windows Mobile 6.5 smartphone.

It means, you have not installed (or no not correctly installed) the
cross compiler and ppu files for wince.
Thanks. How should I do this (compare with above, describing how I have tried to do it, and which worked OK with 0.9.26)?

Have you seen this page:
http://wiki.lazarus.freepascal.org/Windows_CE_InterfaceI have the reference, and it appears similar to what I have done. It does refer to 0.9.26/2.2.2 etc (which works OK on my installations), and not to 0.9.29/2.4.1 (which I need for the clipboard facility in wince). It does refer to various scripts which are needed to cross compile, and I do not understand what these are for, and how you do it. Is it for source code lazarus only. On each occasion, I have downloaded binaries - will these need the same treatment?
Mattias
Thank you for your help so far. I will send you whatever files you need.
Regards
Peter
