Re: [lazarus] FPC compiler for virtual machines?
I've been investigating, and came to the conclussion that the best compiler I can do IS NOT a compiler, BUT an specialiced translator. I could use customizable templates to transform Pascal code into each VM's natural language, then take advantage of the command-line compilers for those VMs. There are open-source compilers that will fit perfectly on this project. At least MTASC, is a much faster and optimal compiler than the actual Macromedia/Adobe Flash compiler. Crappy and cheaty, maybe, but will output the best optimal code possible, and also will save myself from the HUGE task of creating real compilers, since I must keep focused on my game engine. If we remove pointers, goto's (...what else?), there is almost a one-on-one correspondence between Object Pascal and ECMA's scripts (javascript and actionscript), Java and .NET. But will require some cheating with the class frameworks (thinking on FPC's RTL and the LCL), like converting TBitmap into MovieClip, as an example. As said it's a language mutilation, but it's something a programmer can live with if he/she wants to target those virtual platforms, Delphi .NET shows that as you mentioned. -Marco _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] FPC compiler for virtual machines?
The guys at mhccorp, did the same:
http://www.mhccorp.com/java.shtml
But, its a closed source project.
In their pages, they said, they made an Object Pascal To Java translator,
and later a Object Pascal to JVM assembler translator.
Yes the idea is having it Open Source, and for at least three VM's:
J2ME, Actionscript2, .NET
Whoever needs another platform can add the templates, and an
implementation of the Virtual Machine Library.
I'll take it to the point when I can display bitmaps and play sounds.
Then I'll drop the project, so I can work porting my engine on top of
it using the {$IFDEF} machete! :D

Re: [lazarus] FPC compiler for virtual machines?
But, how knows ? Maybe the games you want to migrate to JVM-based phones, can be fun and even profit !!! ;-) Many games can be migrated to VM's that don't need a lot of processing power, think about the best selling Tetris ;D Also, what happens if a compiler maker or chipset builder finds out that developers are using Pascal on mobile devices... they might get interested since there is a visible market. They could make a real compiler or even better a chip with a Pascal Virtual Machine!! If there is a market, there is always a chance for these things to happen, if no one migrates applications the possibility is just zero. -Marco _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] FPC compiler for virtual machines?
I'm building right now a translator of Object Pascal to ECMAscript. I just need a common run-time library, which I'm building on top of FPC's RTL and the LCL. If someone wants to have a portable application, they just have to use the classes of the Virtual Machine Library (VML, not to confuse with VCL). Later, the translator will just change the syntax from Object Pascal to the VM's natural language using a template, then compile the application with an open-source or SDK's compiler, and integrate everything with a version of the VML for the target platform. From the programmer's point of view, it work exactly as an optimal Pascal command line compiler. That's my strategy. -Marco 2008/2/7, mramirez [EMAIL PROTECTED]: Quoting Felipe Monteiro de Carvalho [EMAIL PROTECTED]: My experience with Symbian makes me think I should have instead started a Java port. The Symbian is such a mess that a Java port would I read somewhere that Symbian was rebuilding its OS from scratch, because of the mess. There is even a Java assembler out there. I'm not 100% convinced that it can't be abstracted just like if it was just another platform. There is a JVM assembler: http://en.wikipedia.org/wiki/Jasmin_%28Java_assembler%29 But, the main problem with the Java ENVIROMENT/FRAMEWORK (Virtual Machine + Standard Library + Programming Language + else), is that is 100% CLASS/OBJECT oriented. Even the JVM assembler works with objects and classes, you can't work with global functions, records, or variables like many of the LCL functions does. As mentioned in other replies, you'll have to mutilate the object pascal version of the language to make it run in a JVM. Trying to migrate the Free Pascal Compiler (FPC) used by the Lazarus could be possible, but with weird, unexpected, poor performance results... Borland/CodeGear make an experimental Pascal for JVM compiler, and both this version and its .NET compiler had pitfalls. Anyway, virtual machines are slow, don't matter how much optimization they have, and require more resources. And mobile devices don't have as many resources that a P.C. does. I suggest you should go for the native development, whether is FPC+Lazarus or other development set of tools.

[lazarus] Threads and OpenGLContext
I'm having problems to make OpenGLContext work with threads. I have a game loop inside a thread, and it is wrapped with a Synchronize(). I know it's not an efficient way, but as a test this solved the weird problems in Delphi (no keyboard response, exceptions, etc). Now in Lazarus it doesn't work. I know I'm using OpenGLContext correctly, since the single-thread setup shows all the 3D graphics. In the multi-threaded version, the window goes black (as it should), but no graphics are displayed.

And now that makes me remember something I wanted to ask: I activate the Debug output window, but it doesn't show the lines generated by DebugLn(). But when I ran the application from GDB, the output of DebugLn() was shown. Regards! 2007/11/30, Marc Weustink [EMAIL PROTECTED]: Marco Alvarado wrote: So we don't need GDB?

Re: [lazarus] some questions
Hello! 1) I have solved all of my unit not found problems by adding all the Path templates. Just go to the main menu Project Compiler Options, and click the right [...] button for Other Unit Files and for Other Sources. At the bottom of the dialog, you will see the Path templates, just add all of them. 2) I have never worked with databases, maybe someone else can help you on this :) Regards! -Marco 2007/11/28, el stamatakos [EMAIL PROTECTED]: Hi All, I would like to start by saying Lazarus seems like the answer I have been looking for, for a long time. I love Delphi and have finally found something similar for Linux. I have a few questions, first I registered to the forums but never received an e-mail back with password so I cannot log in. I have two questions that pertain to the Linux version of Lazarus 1) I use a form and then I click in the OnCreate Event Handler in the object inspector and it returns an error Unable to find method. Plz fix the error shown in the message window.. I look at the message window and the error is Error:unit not found:Forms. I take the same code into windows and do not have this problem. Any ideas. 2) I would like to use MySQL with Lazarus. I have no idea where to start. I placed a MySQL50conn module. I then tried to connect to the database using the HostName, DatabaseName, userName, password. Is there a field for port? Is there a simple example to retrieve data from a MySQL. I have a form that essentially has some combobox and they are to be filled with info from the MySQL database. Please help. Thanks I look forward to joining the forums and receiving help.

I'm creating the component dynamically. The example that comes with
this component works for me, but I can't make it compile in my
application.
Do you know where the LCL is defined? Maybe I have to include another unit.

The define comes from the LCL package.
What target platform do you use?

[lazarus] Creating TForms dynamically (works in Delphi, not Lazarus)
I need to create my forms dynamically. In Delphi I just remove the designed form from the main program, so it looks like this: ... begin Application.Initialize; Application.Run; end. Later on, I just create new instances of my forms and assign it's properties, i.e.: ... AForm := TMyForm.Create(Application); AForm.Caption := 'This is my form'; AForm.Left := X; AForm.Top := Y; AForm.Width := Width; AForm.Height := Height; AForm.Show; ... In Delphi that's all I need, and it works. But must be missing something in Lazarus, because the program runs and executes without exceptions, but there is no form shown. I included Forms and Interfaces in the uses clause. Any ideas?

Re: [lazarus] Creating TForms dynamically (works in Delphi, not Lazarus)
Sorry, this is the part that is inside the initialization section: Application.Initialize; Application.Run; Not in the main begin..end, so it should execute before the main program creates the window. Anyway, maybe the way the widgetset works is not the same as the way VCL works. Maybe I should use some event of TApplication to make sure the code executes in the right order. :) 2007/11/26, Mattias Gaertner [EMAIL PROTECTED]: On Mon, 26 Nov 2007 12:05:27 -0600 Marco Alvarado [EMAIL PROTECTED] wrote: Oh, forgot to tell, this part: ... begin Application.Initialize; Application.Run; end. is inside an unit's initilization section.
