Dear all,

Is there possible to convert Delphi code of FreeReport and tiOPF to FPC/Lazarus? Or are there any attempts done? Any hints will be appreciated. TIA.

LazReport is based on FreeReport:
http://lazreport.sourceforge.net/

So with some effort (converting forms etc.) FreeReport should be compilable as well.

I have looked at tiOPF, because I would like to use it in Lazarus myself.

The core should compile quite easily. It's programmed quite clean, does not seem to have Windows dependencies.

The persistence layers are a different thing: IBX will compile (maybe not easily), Indy 9 should, I think Marco got it running. The ADO layer not, because we don't have ADO. Oracle: No idea.

I think the best option would be to try and go for writing a new persistence layer, based on SQLDB or so.

I haven't looked at the visual components, though.

tiOPF version 2 has already been converted to Free Pascal. I convinced my client to sponsor the work for their next project, and did it during Desember. Get the latest tiOPF framework from the TechInsite SVN repository.

Regarding the persistence layers. I only needed Firebird support, so started with that, but persistence layers are quick to write. Anyway, I started by using the SqlDB components that came with FPC. I got it working, until I needed to execute a few sql statements under one transaction (and the sql statements had parameters). It was a weird problem, I will attend to later.

I also needed Server Services, which SqlDB doesn't support and found another free firebird component set called FBLib (Firebird Library). I created another persistence layer using these components and they work 100%. I am currenty using these in my latest comercial application.

I would still like to get the SqlDB components working 100%, as it will be easy to add more database vendor support to the framework. SqlDB is similar to Delphi's dbExpress.

Peter Hinrichsen metioned the other day, that he will be using the Free Pascal compiler with the tiOPF framework for his first Linux project. He normally uses Oracle and XML, so will most probably complete those persistence layers under FPC/Lazarus.

Regarding the visual components. I opted to do the same as I have done with Kylix and the tiOPF. I rather use the Model-Gui-Mediator (MGM) pattern, to hook the tiOPF objects to standard GUI components instead of converting the tiOPF GUI components. Again, converting the components are not difficult, it is just much easier to get cross platform abilities when using standard components. You can also swap out other components it the need arises without issues. Look in the tiOPF SVN repository under Demos for my generic mediating views I created.

On the reporting side. I haven't decided what to use in my latest project yet. I was going to give LazReport a go. Under Kylix I used Report Manager. There are talks about getting Report Manager to compile under Lazarus as well.

Visit the news.techinsite.com.au News Server if you want more support on tiOPF under Free Pascal and Lazarus.

Excellent news !!

This is not yet official ? The latest stable version is 1.41 ?

Any chance of donating this persistence layer to tiOPF ?

Even more excellent news :-)

Lazreport is based on FreeReport (fastreport 1 or 2). Fastreport 3 is a good engine, 2 was not very good because of it's extensive use of global variables, but you can create excellent-looking reports with it.

Thanks for this update. You just clinched the decision to create a new commercial application with Lazarus instead of Delphi :-)

Peter H. , myself and a few others have been using v2 under Delphi for more than a year. It has been stable for some time now. Some class names and some unit name have changed, and has made it much easier to use than v1. V1 is now in maintenance mode, all new features are added to v2 only. There are a few people than have some large projects under v1, that don't want to move yet, but for all new developement work, v2 is recommended.

Already done. Both the SqlDB and the FBLib persistence layers can be found in SVN (tiOPF2 only). The SqlDB layer still needs to be refactored, to make it even easier to add the other supported SqlDB databases as well. Any help would be great. ;-)

I am in the process of setting up my Linux server to do nightly builds under FPC as well. PeterH only does them under Delphi.

Lazreport is based on FreeReport (fastreport 1 or 2). Fastreport 3 is a good engine, 2 was not very good because of it's extensive use of global variables, but you can create excellent-looking reports with it.

I will have a look at LazReport soon.

Could you please give more information about how to download tiOPF through SVN? I didn't find information in
http://www.techinsite.com.au/ about it. Or I didn´t search good, sorry.

I only noticed now, PeterH still needs to update the website for the SVN access. I'll send him a note.

The quick answer:
svn checkout http://tiopf.techinsite.com.au/svn/tiOPF2/Trunk Source

The long answer:
The attached script will checkout (on first run only) or update your working copy from SubVersion. It uses the svn.exe command line client and will create the following directory layout. The script are currently for Windows only, but the commands under Linux should be very similar.

\tiOPF2
\Source <= From svn\tiOPF2\Trunk
\3rdParty <= From svn\3rdParty
\3rdPartyGUI <= From svn\3rdPartyGUI
\Demos <= From svn\Demos
\Images <= From svn\Images
\SupportApps <= From svn\SupportApps
\_Bin <= From svn\_Bin

All you need to do is modify the "svndir" variable on line 5 to point to the location of your svn.exe file.

NOTE FOR Free Pascal:
When compiling under Free Pascal, only the svn\tiOPF2\Trunk is needed. All the other folders are only needed when compiling under Delphi. The DBDemos have not been updated for FPC yet (I must really get to that).

A very excellent news indeed! :D I'm very exciting to know that tiOPF has been run and compiled using FPC. I'll take a look at it soon. I think this also would be nice if mention on FPC/Lazarus wiki (contribution section?).

Thank you for the great work. I believe the FPC community will really appreciate this. :)

What platform are you developing under? I have only tested tiOPF under Windows and Linux.
