you wrote

Don't compile Lazarus to get the bug, compile lazarus/lcl/components/mwedit/release/mwcustomedit.pas

That was a typo, becuase lazarus compiles fine. I tried mwcustomedit which wouldn't compile. There are at least some references to windows unit which all need to be removed.

btw. I'll remove the unit alias code from the compiler. Florian and Michael are against it.

Peter

It already exists -Sd or {$mode delphi}

Unit aliases would be important for migrating existing apps.

The code is placed in an ifdef so it's not completly removed yet.

Peter

I agree. Couldn't there be some kind of command line switch that would turn the "delphi compatibility"
option on or off. That way you can compile source using the "stricter" compiler settings if you wanted to. Unit aliases would be important for migrating existing apps.

Cheers,
Kevin.

I just updated from CVS and re-cycled the compiler. Everything worked fine and Lazarus compiles fine. I then went to the mwedit/release directory and compiled mwcustomedit and that worked fine too.

I added mwcustomedit to the uses clause in MAIN.PP in the lazarus directory and added a mwedit : TMWCustomEdit in the TFORM1 class of MAIN.PP and tried to compile LAzarus.pp. I constantly get internal error 9999.

Any thoughts? Wnat me to update CVS with the change so you can try it, or coulsd someone just add it to their own MAIN.PP and try it please. Does it crash for everyone?
I'm going to reboot and see if it's a memory thing but I'm not going to hold my breath... Shane

Are you referring to the assembling error or something else? Shane

The bug with 'inherited property' has been killed. Now a lot of $ifndef FPC's can be removed.

btw. why are there 2 versions of mwedit?

Don't compile Lazarus to get the bug, compile lazarus/lcl/components/mwedit/release/mwcustomedit.pas

That's when the assembly error occurs.

I can't reproduce the bug with mwCostumEdit with the incorrect assembler generated.

When i compile lazarus i got first 'windows.ppu not found' bugs. After adding unit aliases to the compiler i got some other error in mwEdit

Unit aliases work with -Ua<unit>=<newunit>

It looks like somewhere the gtkwin define is gone, so some parts are included in ./gtk/glib/glib.pp and ./gtk/gdk/gdkprivate.pp

I just removed the conflicting lines and lazarus links well.

Marc

Yes, I am not calling the CREATE because it's crashing during the compile, not while I'm running it. I DO have the code in MAIN.PP to call the create, but I'm not getting a changce to run the program....

Here's more info. If I change TControl and the compiler needs to compile that along with mwcustomedit.pas, then it compiles. If I simply change LAZARUS.PP or MAIN.PP then it crashes.

Not a big deal I guess. To get around the problem I just change CONTROLS.PP and it recompiles everything.

So, I added a mwedit1 component to the MAIN.PP file and call it's create. It goes into the create and crashes when it assigns the TTimers ONTIMER event.....odd. Not sure why yet.....but at least I got it to compile so I can look at it....

I will try this as soon as I'm home. If I understand it correctly, you only added a reference, and declared a var. You didn't try to call TMWCustomEdit.Create ???

It's a pity. It could be handy for compatibility

Marc

The reason for this was that I was originally working on getting the latest beta version of mwedit to compile. At the same time, Shane was working to get the release version to compile. The release version has less units and was easier to convert, so we checked it in and decided to get it to compile first. But the beta version is closer to the next release of mwedit, so we really should try to get it to compile too. Otherwise, we are going to have to do this all over again with the new version of mwedit. We just wanted to do the release version since it was smaller and we thought we could get it working faster.

But here is the result when i'm trying to compile mwCustomEdit:

Compiling mwCustomEdit.pas
Fatal: Can't find unit WINDOWS

Actually, I fixed the error by enclosing it in an {$IFNDEF MWE_FPC} block last night and committed it. This allowed it to compile. You can find it by looking for the above IFNDEF line or by looking for "Result := inherited Font". I also added a TODO comment. The function that contains this is the TmwCustomEdit.GetFont function.

If you remove the IFNDEF and try to compile the mwcustomedit.pas unit with the -al switch, you will get the error and the .s file.

Curtis

Ok, some report on experiences this weekend.
I finally got a compiled lazarus with a reference to mwCustomEdit. You get an internal error on compileing when something is changed in Controls and mwCustomEdit isn't recompiled. Somewhere the dependencies get mixed up if you do just a make. make clean;make works fine.

After runnig lazarus it dumps. This has something to do with the last changes I made. With the introduction of Handle/HandleNeeded/CreateWnd, at least GTK (but I guess GT and WIN also) objects (merely forms) are created when they are needed. So in the Application.Init part, the LCL object structure is created. In Applucation.Run, the GTK/GT/WIN objects are created. This you can see in the debug output.

The reason why lazarus crashes now is that some routines assume the window is already created. Like InvalidateWnd (the reason now). Since the window isn't created yet, a call to invalidate sould do nothing. (The moment the window is created it has (re)drawn itself already ;-)

In the next days I plan to look after these kind of routines to fix them.

Marc

The bug with 'inherited property' has been killed. Now a lot of $ifndef FPC's can be removed.

Peter

If you are compiling the right one, there is a {$IFDEEF MWE_FPC} to use a different "uses" clause in the case of compiling with FPC and it should use LCLLinux instead of Windows.pas....

Hmmm.... strange things happen here. I had to recompile the compiler to get the ReallocMem support.... This intruduced some other nasties.

I tried to make lazarus, after I changed the followeing line in the ./lazarus/Makefile:
NEEDUNITDIR=../fcl/$(OS_TARGET) ../rtl/$(OS_TARGET) ../gtk lcl lcl/components/mwedit/release

So it compiled. Great, but didn't link:

Linking ./lazarus
/mnt/hdc/usr/src/fpc/gtk/gdk.o: In function `GDK_FONT_XFONT': gdk/gdkx.pp:112: undefined reference to `gdk_debug_level' gdk/gdkx.pp:112: undefined reference to `gdk_show_events' gdk/gdkx.pp:112: undefined reference to `gdk_stack_trace' /mnt/hdc/usr/src/fpc/gtk/glib.o: In function `SET_YEAR': glib/glib.pp:1647: undefined reference to `exportfunc' glib/glib.pp:1647: undefined reference to `exportprefix' glib/glib.pp:1647: undefined reference to `exportcache' An error occurred while linking ./lazarus

What's this, do I have to upgrade my gtk libs ???

Marc.

BTW if I do a make again I get an:
 mwcustomedit.pas(31,10) Fatal: Internal error 9999

Great. Line 31 col 10 does not exist.

even without make:

marc:~/fpc/lazarus$ ppc386 lazarus.pp
Target OS: Linux for i386
Compiling lazarus.pp
Panic : Internal compiler error, exiting.
mwcustomedit.pas(31,10) Fatal: Internal error 9999

This is very cool. Somehow, I missed this when I went through the FPC documentation. I didn't know FPC could do this. That gives us the unit alias funcitonality that Delphi has. So we can use this to alias the LCLLinux unit with the Windows unit when compiling under Linux. We can also use this with the WinTypes and WinProcs units just like Delphi does. This is great and gives us one more thing to be compatible with Delphi :-)
