#10 — Announcement: Free Pascal Compiler Delphi XE Port Project

Hello,

I have finished with Phase 1 of the Free Pascal Compiler Delphi XE Port 
Project:

http://www.skybuck.org/FreePascalCompilerDelphiXEPortProject/


All code with porting issue's have been disabled by me.

(The RTL is not used, instead small portions of it where copied to 
unit_skybuck_types.pas for the time being).


By disabling/commenting all code porting issue's it's now possible to fully 
compile the free pascal compiler in Delphi XE which should be a great help 
to programmers all over the world that want to help with this new project !

Programmers should now be able to fix any bug in any file, they can all 
working in parallel.


This project is open to anybody skilled enough at fixing porting issue's... 
these are probably/hopefully little issue's like... fixing pascal-array 
features which are not supported in Delphi. (How to exactly fix these 
issue's could be further discussed perhaps via e-mail, a forum, 
newsgroups... not sure yet where we could discuss this... I'll probably 
setup a nice little forum for us to communicate via the website... )


I also hope that the original developers of free pascal might take a little 
peak and perhaps help out at fixing their own compiler so it becomes 
"portable" again.

You should have and/or install a latest version of Delphi... (Delphi XE 
preferably) that would be great... then you have all the advanced tools that 
you need to fix this code ! ;) =D

Perhaps your code might even benefit from this. Perhaps it's also easier to 
navigate to certain things.


Do see SkybuckChanges.txt to see what I did to source code...

I shall also paste a link to the source code right here so you don't have to 
wrestly through that somewhat whacky/messy website ;):

http://www.skybuck.org/FreePascalCompilerDelphiXEPortProject/fpcbuild-2.4.2-delphi-xe-port-version-002-do-not-use-free-pascal-rtl.rar

Good luck to all and may the force be with you ! ;) =D

Bye,
  Skybuck.

Hello,

Little blog:

I have experimented with subversion + google code hosting + delphi xe 
build-in subversion client + rapid svn.
I spent a whole day trying to figure this stuff out but with success.
The subversion experience seems slow therefore I have trimmed down the 
project to an absolute minimum of files so that downloads/checkouts can 
happen fastly.
So in short: I have now setup a subversion server so that we could work in 
parallel.
However this will not be your typical subversion experience, since I have my 
own versioning methods and I don't really like subversion... it's too slow 
and fok-ups are just around the corner...
However it will come in handy for this phase2 and it will come in handy for 
parallel work.
After the parallel work/fixes have been completed the trunk/revisions will 
probably again be removed, or perhaps it will be stored for historic 
reasons... however new branches will be created for further experimentation.
Zip files will probably be main way of distributing all necessary files but 
perhaps I might change my mind later on... and perhaps I will start to use 
subversion more seriously... for now don't count on it staying up long ;)
So if you want to join in with fixing free pascal compiler so that it can be 
successfully compiled in Delphi XE then here is your big chance to join in ! 
;) =D
Meanwhile you can also gain some experience with subversion... it's actually 
quite fun now that I am getting the hang of it and understand it a little 
bit better ;) (I have tried in the past that probably helped ;) :))
Perhaps I will create some little tutorials maybe even some video's to help 
you started with working with subversion, delphi and this project.
For now this little help right here will have to do (all subversion-noobies 
are welcome ! ;) :)):

What do you need to participate in this project:

1. Delphi XE
2. A subversion client (Delphi XE should have one build in, otherwise 
download Rapid SVN (it's free)).
3. A google account.
4. The following information, enter this subversion link into your client 
(repository):
https://free-pascal-compiler-delphi-port.googlecode.com/svn/

My advice is to select the "fpc-build" folder and download/check it out to 
your computer.

"fpcbuild-2.4.2-delphi-xe-port-version-004-make-fixes"

Copy & paste the folder name to a new folder on your computer, and rename it 
as follows, example:

"P:\fpcbuild-2.4.2-delphi-xe-port-version-004-make-fixes-working-copy"

For now you can only download the sources via svn (subversion), but you 
should also be able to make changes,
simply use Delphi XE to make changes/fixes to files.

5. For you to be able to commit (send fixes to the subversion server) I need 
to add you as a "project member".
I need to add your e-mail which you associated with your google account to 
the "project committers" list.
Once I did that you should be able to "commit" your changes.

So if you want to participate in this project send me an e-mail:
skybuck2000@hotmail.com

Then I will put you on the committers list and you can go have some fun ! ;) 
=D

In case subversion is too difficult for you or you don't like it or you just 
want to have the latest files then here is the latest 
"release/distribution".
I removed all unnecessary files and it has become much smaller and much more 
easy maintainable me thinks for the time being (i386/x86 only ;))
(However it should be able to later integrate changes back into the main 
releases, so don't worry about that ;))
fpcbuild-2.4.2-delphi-xe-port-version-004-make-fixes.rar

I hope some of you will join, that would be cool ! ;) =D

Bye for now,
  Skybuck.

The short story so far:

Hello,

This project is about "porting" the Free Pascal Compiler to Delphi XE.

More information can be found on this little blog:

http://www.skybuck.org/FreePascalCompilerDelphiXEPortProject/

A subversion server has been setup here:

https://free-pascal-compiler-delphi-port.googlecode.com/svn/

The latest release/distribution is here:

http://www.skybuck.org/FreePascalCompilerDelphiXEPortProject/fpcbuild-2.4.2-delphi-xe-port-version-004-make-fixes.rar

The source code compiles, however little sections of code have been disabled 
as follows:

// *** Skybuck: Fix Needed ***

These sections are slight free pascal language incompatibilities with Delphi 
and need to be fixed...

There are about 700 of them. (Many duplicates here and there though).

Will you help fixing these issue's ?

If so you can either help by using subversion or simply working via e-mail 
and selecting a file to fix.

Me e-mail is: skybuck2000@hotmail.com


After the compiler is fixed it can be extended to support new 
hardware/platforms and virtual machines, perhaps even converters... like 
opencl/cuda/ptx/php/java/.net/c/c++... pretty much anything can become 
possible afterwards. It's good to have an open-source delphi alternative, if 
you agree with that then help out and together we rock the cradle ! ;) =D

Bye,
  Skybuck.

#13

Ok,

I gave google code a try but it doesn't have all the features I want, so I 
am switching to sourceforge:

https://sourceforge.net/projects/fpcfordelphi/

(I especially like/what the bugtracker ! ;) =D)

Bye,
  Skybuck.

Hi, can you give an example or two of why this is beneficial?  What
are the advantages of being able to compile freepascal in Delphi?

Hi,

Easy modification of code, and easy debugging, in other words more easy 
extending it and developing it further.

Also Delphi has very strong error checking which is helpfull too.

Delphi IDE probably more high quality and stable than say Lazarus.

Delphi little bit faster compiler too.

And personally I feel right at home in Delphi ! ;) =D

Like fish-in-water =D

  Skybuck =D

Porting Freepascal to Delphi won't give you a freepascal backend with
a delphi IDE frontend, so I'm still confused what the benefits are.
What exactly are your goals?  To develop code in the Delphi IDE but
compile it with freepascal?  Extend freepascal with Delphi syntax?

Maybe a clear statement of what you're trying to accomplish would help.

For now the goal is easy:

"Compile free pascal with Delphi".

The next (personal) goal for me is:

"Add support for virtual machines and other machines"

(By writing internal assemblers).

I think that's what you mean with "backend"... so yes after the "port" is 
done I want to try and attempt to write a back-end maybe even multiple ;)

Others might use the free pascal delphi source for other things... like work 
on front-end or so.

(I am much faster at developing code with Delphi than with any other tool, 
so that's why I want free pascal ported to Delphi (there are many other 
reasons though)).

(I also find it very important to have my own "object pascal compiler" for 
the future... (So I don't have to worry about being left standing in the 
cold ;) =D))

Bye,
  Skybuck.

OK, so you savaged it as well...

Why in the world should I need Delphi for that, when I can use
FreePascal itself on all supported platforms to do the same?

So it is with FreePascal itself.

What FreePascal really could use is it's own native debugger (this is
where Delphi still is way aheaed IMHO).

That and the fact that FP has serious issues with some serious large EXE 
files.

Really? It seems I've read more than my share of FAQ's on the
subject. It just does not seem to help, much..

When was the last version you tested? Are you talking about in general
or via Lazarus? If you haven't tried since a year or so, you may want
to try again: the internal linker on Win32 improves things a lot. In
particular, see "smartlinking": -CX, -XX -Xs, -Os, etc.

It works in general for heaps of people. It could be that you are doing
something wrong, have outdated configs that obscure the vision (specially
upgrading Lazarus is not fool proof, and I recommend to verify
deinstallation of the old one, including config directories before
installing a new one)

So IMHO you shouldn't state such things as universal truth, while it might
be a problem of your configuration.

And the fact that the Borland Pascal compatibility for one feature that was 
introduced when smartlinking was introduced (TP4? TP5?) is still not present in 
FPC, in casu the fact that when I use a declare of

const
   list_ptr: listptr = nil;
   list_top: listptr = nil;
   list_end: listptr = nil;

and my code only implicitly references list_top via a call to a procedure with 
an untyped parameter, passing only list_ptr, FPC smart^H^H^H^Htupid_links it away.

And yes, like another poster mentioned, the debugger stinks, and given that the 
full TP6 source, whether original, or reconstructed has been available for at 
least two decades, the FPC IDE is an absolute C of C.

Perhaps I will not continue this project, unless I get some help from 
others.

Because it's quite a lot of work and Lazarus seems to be quite good now... 
at least is supports fpc 2.4.2 and is out of beta...

So me give that a try for my purposes though it would still be nice to have 
free pascal compiling in Delphi.

However Lazarus does have some IDE features which Delphi does not have so it 
could be interesting to use Lazarus for a while...

But this is all new so my oppinion about Lazarus might change... but for now 
it seems sufficient for doing what I want ! ;) =D

And that is adding my own target to it ! ;)

  Skybuck.

Lazarus does not support fpc 2.4.2.
The FreePascal compiler (2.4.2 or higher) is needed to build current
Lazarus.

A matter of semantics...

What I ment is "Lazarus comes with fpc 2.4.2 and in that regard it supports 
fpc 2.4.2 or in other words it uses fpc 2.4.2 binaries to compile the user 
sources".

So the developer of Lazarus thinks fpc 2.4.2 is a good thing and uses it 
instead of an older version like fpc 2.2.0 or so...

Perhaps there are differences between fpc 2.4.2 and fpc 2.2.0 so it's good 
to know that Lazarus uses the latest one and has no issues with it ! ;)

So again in that sense Lazarus supports the latest fpc 2.4.2 command line...

It's especially nice for me at least since I also use fpc 2.4.2 sources ! ;) 
=D

Bye,
  Skybuck.
