failed to start wince-application with ZeosLib
Posted: 09.01.2009, 18:08
Hello forum,
I'm new to Lazarus + fpc + zeos. So please forgive me my school-english and my stupid questions.
I installed lazarus with fpc and wince-cross-compiler. Compiled applications works with win32 and wince. There seems to be no problem.
An application with ZConnection works under win32 without any problems, but under wince the application is started and suddenly ended. It won't show any errormessage or the form or anything else. This only happens, when I use ZConnection.
While compiling my application with zeoslib for wince I get errors. I only get these errors, when i try to compile for wince.
Perhaps it's not a good idea, but this was nesassery to continue compiling. To compile win32-applications successfull I've to change again from PWiderChar to PChar.
I tried 'peinfo' (wince) for checking depencies, but all needed dll's are existing and are loadable.
Does anyone have an idea for compiling applications with zeoslib without manupulating the sourcecode?
On win32 I had to copy ntwdblib.dll to system32-directory, but for wince i didn't find this file. Do I also need the ntwdblib.dll for wince? 'peinfo' didn't say anything about this dll. Where can I get it from?
Normally I'm coding in Delphi 2007. Would it be better to "integrate" fpc and zeos in Delphi than using Lazarus? Any expierence?
I invested more than three days for googling, forum-reading, changing options, compiling, testing, changing more options and I don't have more ideas...
I know, these are a lot of questions, but I would be glad to hear an other opinion.
Thanks a lot!!!

I fixed this with changing PChar to PWideChar in lines 172 and 209.PWideChar expected, but PChar found (ZPlainloader.pas)
Perhaps it's not a good idea, but this was nesassery to continue compiling. To compile win32-applications successfull I've to change again from PWiderChar to PChar.
To continue compiling I removed these few lines beginning from line 2586. So the application is compiled, but won't run on wince. Start and stop, no form, no messages, nothing...OemToChar and CharToOem not found (ZAbstractRODataset.pas)
