After some time I tried to compile lcl-qt on linux-amd64, and I got some compilation errors.

Please remember that not all machines are 32 bit, so whenever you cast handles, pointers and so on to integer types you shouldn't assume they are 4 bytes large.
If you need to do such casts, use PtrInt/PtrUInt: they are signed/unsigned integer types of the same size of pointers (so they are Integer/LongWord on 32 bit machines and Int64/QWord on 64 bit machines).

These are the errors I have:

qtcaret.pas(139,33) Error: Illegal type conversion: "DWord" to "QPixmapH"
qtcaret.pas(269,6) Error: Illegal type conversion: "QPixmapH" to "DWord"
qtcaret.pas(272,34) Error: Illegal type conversion: "QPixmapH" to "LongInt"

Explanation:

line 139, CreateCaret function:
ColorCaret is cardinal, so it cannot be cast to a QPixmapH on 64 bit machines.

line 269,272 TEmulatedCaret.CreateCaret method:
A QPixmapH is cast to a Cardinal.
A QPixmapH is cast to an Integer (moreover, CreateColorPixmap wants a Cardinal:
maybe CreateColorPixmap should be modified too to accept a PtrInt/PtrUint?)

I didn't provide a patch because I don't know qt-lcl internals and I don't want
to break things.

bye,
Giulio

will be fixed, tnx for report.

can U test it now , and possibly send feedback ?

tnx

I get this error yet in 64 bit machine

lazarus/lcl/interfaces/qt/qtcaret.pas(269,6) Error: Illegal type conversion:
"QPixmapH" to "DWord"

Thanks

Still compilation problems.
This patch should fix it (I hope).

Howver, on my 32 bit chroot environment lazarus ide compiled for qt (qt 4.3) starts, while the 64 bit version crashes, so I think there are still problems here and there.
I'll try to investigate.

Giulio

tnx, any hint for 64bit will be appreciated (I don't have an 64bit machine)

tnx, patch applied.

maybe you should recompile libqt4intf on your own. It can causes problems.

I never compiled a 64bit verson ?!

I don't know ;), I just want to help to Giulio, I have to recompile bindings each time since I cannot use it (glibc-2.3.6 & qt compiled with -no-sse2).

so it works now ? Giulio ?

I still have problems... but it's very strange.
After your patch, lazarus starts (via ./startlazarus). However keeps crashing when starting it with ./lazarus, and gdb tells me something that shouldn't be related to the timer issue.

In fact, when lazarus starts it tells me that last project made lazarus crash, so a dialog box asks me if I want to try to reopen that project or not. When I click a button in the dialog, the ide crashes. What happens is this:

The dialog is created from QuestionDlg, that at some time calls ShowModal (of CustomForm).
ShowModal does a
ActiveWindow := GetActiveWindow;
(in the qt interface, it asks to the bindings for the active window, and then finds the qtwidget object if I understood correctly). After showing the Dialog, ShowModal does a
if ActiveWindow 0 then SetActiveWindow(ActiveWindow); In qt interface, we have

procedure TQtWidget.Activate;
begin
  QWidget_activateWindow(Widget);
end;

Widget passes TheObject, but TheObject is nil, so there is a SIGSEGV.

This is what seems to happen, but I'm a bit lost, and compiling with -dVerboseQt gives a lot of compilation errors.

hm ... I don't have 64bit linux installation, so cannot help. Any ? I would like that we have 64bit compilation/running before 0.24 go out. Giulio, if you have any ideas || patch please provide so I can test against 32bit and if it work it will be commited.

grazie :)

Ok, sorry, it's not a bug related to 64 bit, However it's a qt interface bug :P
You can reproduce it this way:

edit your .lazarus/protocol.xml so that it's like that:

<?xml version="1.0"?>
<CONFIG>
<Protocol Version="1">
<LastProjectLoading Failed="True"/>
</Protocol>
</CONFIG>

start lazarus with ./lazarus.

It fails even on 32 bit, in the way in wrote in the other mail. I think it should be a qt-interface bug because a gtk compiled lazarus starts fine in these conditions.

Probabily I had my protocol.xml set like that because of former crashes of qt-lazarus, and then I had it crashing because of this (not 64 bit) bug :P

bye,
Giulio

ide is still "watch but don't touch" :), but has huge progress last days, bugs will be fixed and ide probably should be useable in next month or two.

Probabily I had my protocol.xml set like that because of former crashes of qt-lazarus, and then I had it crashing because of this (not 64 bit) bug :P

so, can you confirm that apps & ide are compileable on 64bits machines in normal conditions ?

tnx
zeljko

Yes. And at a quick glance 32 bit and 64 bit versions look the same :)
