Execution problem under Lazarus/Code Typhon

DidiL · 2015-01-06 02:58:57

Hi,

I need some help to use mORMot with FPC/Windows 8.1

Using
CodeTyphon32 5.1 / FPC 2.71 / mORMot 1.18
sqlite3fpc.7z (fpc-win32) -> mormot dir
sqlite3obj.7z (obj) -> mormot/sqlite3 dir
sqlite3.dll -> output dir and system32

Compilation error:
SynCommons.pas(9438,14) Error: function header doesn't match the previous declaration "SetProperty(var tvardata;const AnsiString;const tvardata):Boolean;"

----

Using
Lazarus 1.26 32bit / FPC 2.64 / mORMot 1.18
Lazarus 1.26 32/64bit / FPC 2.64 / mORMot 1.18
Same SQLite3 deployment.

Compilation: OK
But execution error:
TestSQL3 project has raised a class exception: 'External: ?' At address: 75262F71

----

Thank you for your help.
We've tried on 3 different computers.

This issue was already documented.
In short, 2.6.4 contains a bug - http://mantis.freepascal.org/view.php?id=26773 - which prevents the tests to pass, and has been fixed in latest SVN trunk (but not in CodeTyphoon 5.1).

You may change the Synopse.inc file, in this section:

   {$ifdef VER2_7_1}
     {$define ISFPC271}
     {$define HASVARUSTRING}
     {$define HASVARUSTRARG}
     // defined if the http://mantis.freepascal.org/view.php?id=26773 bug is fixed
     // you should use 2.7.1/trunk branch in revision 28995 from 2014-11-05T22:17:54
     // => this will change the TInvokeableVariantType.SetProperty() signature
     {$define FPC_VARIANTSETVAR}
   {$endif}

Undefine FPC_VARIANTSETVAR conditional.
But the tests would not pass either.

You need the latest SVN 2.7 trunk so that this http://mantis.freepascal.org/view.php?id=26773 bug is fixed.
Codetyphoon is outdated.
We use http://wiki.freepascal.org/fpcup to compile it, and not CodeTypoon, which has strong licensing issues.

Thanks Arnaud,
I tried again this morning but got a FPC 3.1.1 version, witch gives me the same FPC_VARIANTSETVAR problem...

BTW I do not know what is FPC 3.1.1...
I only know the 2.6 and 2.7 branches - see http://www.freepascal.org/develop.var

I guess what you call FPC 3.1.1 version does not have the 26773 fix included.
Ask FPC guys for including the fix!

I've asked them for them for the exact command line to get 2.71 specific version using fpcup.

Please see http://synopse.info/forum/viewtopic.php … 502#p13502

As a quick (and dirty) solution, I've found binaries for this version.
http://vdebris.wordpress.com/lazarus-2-7-1-snapshot/

The test project is successfull (except URI root)
Let's play with the mORMot!

Sorry to resurrect the thread but I'm having this issue with FPC 3.0.1. Won't it be better to change that ifdef in synopse.inc and use the FPC_FULLVERSION define instead? (In order to don't need to update the condition after new fpc version releases).

Something like:

{$if FPC_FULLVERSION >= 20701} 
{$define ISFPC27}
{$endif}

I'm not sure if this would be ok since I'm not very experienced with FPC (and have no experience with mORMot), but it seems to be easier to maintain.

I already tried that...

But this won't be allowed in a Delphi file AFAIR....

brian_ch · 2015-02-25 02:50:47

Hi, thanks for the reply,

what part won't be allowed? This part of the file is inside a "{$ifdef FPC}", so Delphi won't reach that condition. (Although it would be better to end with "{$ifend}" and not "{$endif}" as in my code above, but even this would only be needed for versions lower than Delphi 6 if I'm not mistaken.)

ab · 2015-02-25 05:24:40

Just try it.
Afair at least in older Delphi, it won't compile, even in a $ifdef fpc...
Buggy delphi...

brian_ch · 2015-02-25 23:53:26

I don't have a Delphi license (or a Windows one hehe). I'm a GNU/Linux user and FreePascal hobbyist (and work with Java for a living).

I was happy that I found here in my house an old Borland evaluation kit CD that has Delphi 5 trial, but I just discovered (with the help of Wine) that it needed registration on the Borland website... I guess it's a bit too late for that. Now I don't know how I'll live without knowing what that problem was, but that's life! hehe
