Error compiling LCL for WinCE

[Legolas]

I'm trying to recompile the LCL for WinCE but I get an error:

Code: [Select]


WinCEInt.pp(123,21) Error: Overridden methods must have the same return type: "TWidgetSet.GetStockObject(LongInt):DWord" is overriden by "TWinCEWidgetSet.GetStockObject(LongInt):LongInt" which has another return type


I have followed all steps I have found here. The raw crosscompiler works fine and the arm-wince binutils are called correctly.

The LCL THandle is defined different than the windows THandle. I'll try to fix that.
For the time being, you can change in lcl\lcltype.pas the line

Code: [Select]

THandle = type PtrInt; into

Code: [Select]

THandle = {$ifdef windows}system.THandle;{$else}type PtrInt;{$endif}

[Legolas]

Sadly same error happens

The line is embedded in a ifdef block:

Code: [Select]


{$ifndef WINDOWS}
  {$IFDEF CPU64}
  // temp solution for 32bit system.Thandle
  THandle = type PtrInt;
  HANDLE = THandle;
  PHandle = ^THandle;
  {$ENDIF}
  ...


Maybe this block is never reached compiling wince?

[Marc]

ah, ok
I only had a quick look, didn't see the surrounding ifndef.

I've to look later what is going on, but from this I think the windows handle is used and that one should be the sam ein all units.
Somehow thandle gets redifined somewhere.

Sure it isn't reached, that block has a {$ifndef WINDOWS}

Windows CE defines Windows too.

It could try to fix it, but it's a little hard to me since I don't have a win64 system, and I don't remember this problem on win32. Was it introduced recently?

[Marc]

This block is only for non windows, so no need to fix that.
The only question is, how comes that there are 2 different THandle definitions ? Where are they defined.

I'm resuming this old post for an error I get compiling the lcl for wince. I use this

Code: [Select]


make lcl LCL_PLATFORM=wince PP=ppcrossarm.exe CPU_TARGET=arm OS_TARGET=wince

in order to get a cross lcl, but  I get this error:

Code: [Select]

The strange thing is that the file Graphics.ppu is exactly where the makefile expects to be.

I guess you are using svn fpc ? Then this is a known issue

[felipemdc]

Just use one of the tested unstable revisions:

http://www.freepascal.org/wiki/index.php/Tested_Unstable_Revisions

Also, please mark on that wiki page that the revision you utilized does not work so other will know that. If it isn´t already marked.

[Legolas]

The wince crosscompiler works fine (rev. 5370). I think the problem is in the lcl, because I can't compile it even if I use a fpc stable version.

[Vincent Snijders]

I don't understand. arm-wince is only supported in the unstable version. So clearly fpc cannot compile the LCL with the stable version.

What error do you get?

[Legolas]

*me crying in a corner
Sorry, for "stable" I meant a tested unstable revision. And now I'm sure I need some sleep: I got these errors because I have put wrong paths in the fpc.cfg file :/

[Vincent Snijders]

No problem :-).

Take a good rest.
