Ok, the latest 2.60 seems to have some issues.

Building an application for win32 that uses SQLite, and the following command->

DB.GetTableNames(tbl);

Gives the SIGSEGV. 2.50 was fine.
The debugger is reporting Exception in TCollection.DoClear. Looking at 2 copies of collect.inc I have, it appears there has been a few changes here.

Also compiling same application for WINCE, has issues relating to the BGRABitmap stuff.
It stops in perspectivescan2.inc, line 1 -> {$asmmode intel}
I think the problem is most likely perspectivescan.inc there is at line 108 there is a {$IFDEF CPUI386} but the else is also including perspectivescan2.inc that is only INTEL based.

Did you have any luck?

A little bit more information for you.
I would get the SIGSEGV just by writing a program that created a TDataset descendant component, and then freed it.

I think you mentioned 2.70 coming soon after website rebuild, so I'll try again then..

Thanks.

Yes, i got SIGSEGV too.
My old project, run without any error with old version of Lazarus (but i don't want to use old version of Lazarus).
Now, i got SIGSEGV, my project use interface to encapsulate Zeos component, so it can be freed automatically on runtime.

I did a test to make sure KpjComp statement about TDataset true,
var   
   Fcon: TZConnection;
   Q: TZQuery;

begin
  Fcon:= TZConnection.Create(Self);
  Fcon.HostName:= 'localhost';
  Fcon.User:= 'root';
  Fcon.Password:= '';
  Fcon.Protocol:= 'mysql';
  Fcon.Database:= 'ppdb2011_pontianak';
  Fcon.Connect;

  Q:= TZQuery.Create(Self);
  Q.Connection:= Fcon;
  Q.SQL.Text:= 'select * from bobot';
  Q.Open;
  Q.Free;
  Fcon.Disconnect;
  Fcon.Free;

end;

SIGSEGV error occured when debugger try to execute
Q.Free;

i don't know, this (maybe bug) because Lazarus Bug, Code Typhon Bug, or my code?

i hope Sir Sternas has a solution for this.

Thanks.

Hello.
Have you tried to run without debugger?
Or have you tried to close query before destroying it?

Sir, try close first, and encapsulate with try/exception (sorry for my poor english)

I did a simple test
procedure TForm1.Button1Click(Sender: TObject);
var Q: TSQLQuery;
begin
  Q:= TSQLQuery.Create(nil);
  Q.Close;
  Q.Free;
end;
it can work properly on Original Lazarus (from Lazarus site) and raise an SIGSEGV exception on Code Typhon Lazarus 2.60.

So i conclude, that Code Typhon 2.60 is released with non stable Lazarus version. Then, i'm waiting for next version of Code Typhon...

Nice one, look forward to 2.70.

(rolling installation)


That sounds nice :), will this be able to SVN updates, and be able to select revision's etc. That would be really nice.

Hi Sternas

any update on when CT2.7 will be available?

I need to do some stuff with Zeoslib so I either wait for 2.7 or try and retro fit an older version of Zeos (possibly from CT2.5 as the latest Zeoslib from their SVN doesn't appear to compile in CT2.6 without some other changes and I don't really want to spend time battling with that if you've already resolved those issues in CT2.7).

hi Sternas

thanks for releasing CT2.70 (you must have been up very late last night doing this).

I noticed the link to the "changes log file" on the home page and on the download page still refer to 2.6 (the "latest version" also says 2.60 even though it's 2.70 now).

Thanks again.
