I modified the program to show a message after a button-click. It seems like a second after the button is clicked before the messagebox appears. I'll have to try bigger programs to see if it's acceptable. Some remark : the first time the messagebox is shown it occupies the whole screen. The second and next times it's much smaller, just the size of the button, like I would expect. Anyway, thanks guys ! Regards, Koenraad Lelong. P.S. When I look at the version of Lazarus in the IDE I see the previous version (11739) instead of 11761 like svn reports.

Hi,

I found where the exception 'Invalid Filer Signature' is raised :

I added writeln's for Filersignature and Signature and this is the
result :
FilerSignature : 4608084
This is only the first three chars of the signature. I wonder why it
is cut of. Maybe an arm bug?
It is due to unaligned data access. It does not raise exception on
arm-linux, but do not handled properly...
It is needed to use unaligned() keyword.
if Signature <> LongInt(FilerSignature) then
must be fixed to
if Signature <> LongInt({$ifdef
FPC_SUPPORTS_UNALIGNED}unaligned{$endif}(FilerSignature)) then
Yury.

I tried this (renamed my form to TestForm1) :
initialization
{$I unit1.lrs}
writeln('test');
TestRes:=TLresource.Create;
TestRes:=LazarusResources.Find('TTestForm1');
writeln('Name:');
writeln(TestRes.Name);
writeln('Valuetype:');
writeln(TestRes.ValueType);
writeln('Classname:');
writeln(TestRes.ClassName);
end.
The result was :
test
Name:
TTestForm1
Valuetype:
FORMDATA
Classname:
TLResource
[FORMS.PP] ExceptionOccurred
unit1.lrs contains :
LazarusResources.Add('TTestForm1','FORMDATA',[
'TPF0'#10'TTestForm1'#9'TestForm1'#4'Left'#3#17#1#6'Height'#2'y'#3'Top'#3#28#1
Any conclusions ?

Tried this, and got another result.

And the form seems to respond to a click on one of the buttons, it

This is some progress, thanks. Other suggestions ?
at leas this is no: "Gtk-WARNING **: cannot open display:"
so you now have your display and ran into a complete different problem.

I read your mail as you use startx OR project1 - which would have been nonsense. My fault, sorry. I'd try ktrace/strace/truss for looking deeper into the problem.

The board does not have a running X-server when booted. I have to ssh to it and do startx. Startx gives me an xterm. What next ? With X running I tried another ssh to it, now with -X added, seems to do nothing, I mean I get a prompt but nothing else. There I tried to start my app : ./project1 -> problem reported DISPLAY=:0 ./project1 -> problem reported I was curious and I tried running the app without a running X : the same problem.

Is this just "xhost +" from the command-line (without quotes of course) ? This does not work on my arm-board. No other suggestions ?

That's the X-server telling you that it cannot open the X display. You can try to run "xhost +" on the X-server, but it is UNSAFE, and ONLY for debugging.
