Hello together!

I want to create a application (gui) with lazarus for wince.
The application should connect to an sql server 2005


I have problems by including the components of ZEOdbo when I compile
for wince

This my steps:

 Until Step 2 (down) I compile for win32 for testing first.!

STEP1:
-> I install the "lazarus-0.9.28.2-fpc-2.2.4-win32"
-> Then the "Lazarus-0.9.28.2-fpc-2.2.4-cross-arm-wince-win32"
-> Open lazarus and generate a new project
-> I do the things in this tutorial
(http://wiki.lazarus.freepascal.org/Zeos_tutorial)
   -> Download the "ZEOSDBO-6.6.4-stable.zip" and extract the files
   -> Download the "TortoiseSVN-1.6.6.17493-win32-svn-1.6.6.msi" and
install this (restart the pc after setup)
   -> make the checkout from windows explore
(svn://zeos.firmos.at/zeos/trunk), it works!
-> Open Lazarus and save the default project1 (the default project
with the empty form!)
-> Compile all (Start > compile all) > no errors!
-> go to package > load packages (lpk) and select the "zcomponent.lpk"
-> In the package zcomponents-form I press install
-> By the dialog with the question recompile i press yes
-> Make the steps with the connectors..

-> TEST - It works!!!!!!!


STEP2: (Now I want to compile for wince / arm
-> I change the compilerconstant


Options > Options "FCP.exe" to: 
B:\lazarus\fpc\2.2.4\bin\i386-win32\ppcrossarm.exe
Project > Paths > LCL-Interface to: wince (beta)
Project > Sourcecode > target-OS to : WinCE
Project > Sourcecode > target-CPU to : arm

When I now compile I received the attached error messages

Can someone help me please?
Support zeosdbo the wince ?
Must I change some files or sources???

Thanks and best regards from germany

unlike win32 api, the wince api uses WideChar for its strings. So
loadlibrary expects a widechar.
You can have a peek in ZEOS trunk (7.x) if they have fixed it there.

Otherwise you can try casting likeCode: [Select]  {$ifdef
WINCE}PWideChar(WideString(Location)){$else}PChar(Location){$endif}

Thanks!

I try it and a few steps later we receive a new erorr

  {$IFNDEF UNIX}
    if doOemTranslate in FOptions then
    begin
      if ToOem then
        CharToOem(Src, Dest)      else OemToChar(Src, Dest);
      Dest[Result] := #0;
    end
    else            

how can I transact the ChatToOem for wince?

Thanks and regards
