Yes, but that's not possible now. So if he want a GUI builder for FPC, he has to port it first.

Exactly. Current Amiga units contains heavy amount of 68k assembly. That's one problem. The second problem is, that some of the system structures also changed in MOS, so i decided to re-implement the units from scratch, instead of hunting for the changes through the MOS includes. But this is a slow and boring job, so i'll need to find a somewhat automatized way to do it soon. Since most of the Amiga units were build with fp2pragma, found on Aminet, i'll think i'm going to adapt fd2pragma to support building of an FPC/MOS unit too. (But fd2pragma is in C, and i hate to programm in C. )

I think they'll definitely work, however, i did not tested it yet. If some special support still needed which does not yet exists in the compiler, it will be added, it's not too difficult. Please note that FPC/MOS compiler (not including the RTL) already has better support for the platform than the Amiga compiler ever had, just take a look on ABox syscall support. Such a thing never existed in the classic Amiga compiler. Also the PPC code generator is already much better than the 68k one was.

Don't know. I never did such a thing. As i said, i'm not really a man of GUI programming.

sure, email it to bartonekdragracing at yahoo dot com


also, I didnt mean if there was a app that builds the GUI for you.. I meant, does FP have commands to build pulldown menus, windows etc ? I'm sure it does by looking at the demo code but it wont compile.

If you can help me get the Amiga version working that will be great. I want to see sample screens (your demos will probably do just fine) etc.

last time I used intuition/graphics.library, the screens looked ugly.. Mui is alot better looking then that, yet I dont want to code in C for now as I'm better at pascal then c.

Free Pascal for MorphOS first unofficial development snapshot is just released. You can get it from here. Don't expect anything big, now it's more likely only a toy for the curious ones than a real tool for real developments, but this will change soon...

Ok, just downloaded it and I can't make it compile anything, even a simple hellworld.pas ;(

With this one:

------- cut ---------
program test;

begin

end.
------ /cut ----------

I got a runtime error of fpc...

And with this one:

--------- cut ---------
program test;

begin

WriteLn('Hello');

end.
---------- /cut --------

I got: Fatal: Illegal character "' '" ($A0)

=> I know you warned to not expect a lot of things from it... But I had expected something more ;)

Leo.

PS: I used "fpc [file.pas]" to compile... With this line, is the link automatically done ? if not, how to compile and link ?

I can't reproduce the errors you reported. Can you send me the files you're trying to compile? Can you specify which runtime error you got exactly? At wich line you got the fatal error in the second example? The compiler works OK for me (the same one i archived and uploaded). Eg:

program hello;
begin
writeln('hello world!');
end.

In fact, the uploaded compiler is capable to compile itself into a working executable on MorphOS, and that is over 170000 lines of Pascal source...

Quote:

Assembling and linking should happen automatically after a successful compile. The compiler will call as to assemble what's needed and then ld to link the whole stuff together into an executable. It will even do the stripping with -Xs parameter on (which is the default in fpc.cfg).

(Note: while writing this, i've discovered that i'd accidentally left out strip from the archive, so you can't strip debug info from executables unless you've MOS SDK installed, or you copied strip from the MOS SDK archive to FPC's bin/morphos directory. This will be fixed in the next release, but this problem shouldn't affect working of the compiler, only result bigger executables, and an "Error: Util strip not found, switching to external linking
" message at linking time.)

If you just can't get it working, you can try to use 'fpc -va [file.pas] > log.txt' command, and send the resulting log.txt to me.

Hi,


Hm, I tried the upper "Hello World" programm after I installed fpc and it worked without problems here.

Maybe you have used the wrong backtics "'"?

Now to find out whether my long lost Modula2 knowledge can help me.

OK, now I cannot reproduce the RunTime error...

But here is the error I got when trying to compile http://nogfx.free.fr/test.pas :

Quote:
The compiler works well, there's really an invalid character $A0 (dec:160) after the word "Begin" at line 6, character position 6. Just turn on whitespace display in your favourite editor, and see. It's probably a typo by you. Accidentally this character is also empty by default, and shows ups as a space.

After the removal of that character, it's working:

I was getting the same thing and gave up... but now since you said that, I will definitely give it a shot...

I take it CygnusED should reveal those white spaces.... oh man, I sure do hope this works.

3rd try ;)

I removed the illegal character from the source and accountered a new runtime error:

PS: Despite the runtime error, it seems the executable is created and works...

Hm,


Nope, not here.

Just corrected the source as told by Chain-Q and it compiled without error.

@Leo:
Runtime error 204: (quote from FPC manual)

"204 Invalid pointer operation
This you will get if you call Dispose or Freemem with an invalid pointer (notably, Nil)"

Since the compiler works OK here, and at other people, my guess there is something wrong at you. Which version of ixemul.library do you have installed? Wrong version could cause memory corruption which can hurt the compiler, and result such error. Do you have MOS SDK installed? If not, did you install strip by hand? If yes, which version? (You need the one from MOS SDK!)

Something wrong with me ?
Nah... I just did a clean reboot.

And: yes, I have SDK, and got ixemul which was shipped with MOS 1.4 so there's nothing wrong here. And I have strip which came from MOS SDK as well...

Leo.

Chain-Q, what about this?

Btw, what libs can we access from FPascal today ?

.DOS/Exec ?
.Intuition/Graphics ?
.CGX ?

Leo.

Most MorphOS-releated units are incomplette yet, and untested. In the current CVS, there are units for exec, dos, utility libraries and for timer.device. I've a partially-done (around 50% completted) unit for graphics and intuition.library on my HDD. There will be units for CGFX and AHI too soon, since i need that for some of my own programs. MUI and other stuff will come later.

Please also note that currently calls using taglists cannot be used, because they're not yet added to the units. This will also change very soon.

(Anyway, i wrote down most of this already in readme.MorphOS, and on the FPC Wiki page, but i know users just never read the @#$(*@*#($&ing readmes... )

[ Edited by Chain-Q on 2004/8/16 10:45 ]

Great work with FPC, Chain-Q. Now I hopefully won't have to use c++, hehe.
Say, how about the CRT unit, when are you going port it?
