Label, font size problems

Hello!
I have problem with my program when I crosscompile it to Raspberry PI.
It is simple form with few labels (standard palette) on and two
buttons.

Code: [Select]procedure TForm1.Button1Click(Sender: TObject);
begin
  Label1.Font.Height := 20;
  Label2.Font.Size := 20;
  Label3.Font.Color := clred;
  Label4.Font.Style := [fsbold];
  Button2.Font.Size := 15;
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  Label1.Font.Height := 0;
  Label2.Font.Size := 0;
  Button2.Font.Size := 0;
end;

When I run this on win7 and I press Button1 I get labels modified
according to code.
When I crosscompile this code on ARM (Raspberry PI), Label1 and Label2
dissapere from screen. Text in Button2 also dissapeare. Label3 become
red and Label4 become bold.
When I press Button2 Label1 and Label2 are visible again in normal
size. The same with button2.

The computer that I am using for programing is Win7, 32 bit PC.
Program is Typhon32IDE v4.8; FPC version 2.7.1; SVN revision: 44546
Library for crosscompile is arm-linux-pi downloades from server this
week.

I susspect that it has something to do with compiling massage
QuoteOptions changed, recompiling clean with -B
project1.lpr(22) Warning: "crti.o" not found, this will probably cause
a linking failure
project1.lpr(22) Warning: "crtbegin.o" not found, this will probably
cause a linking failure
project1.lpr(22) Warning: "crtend.o" not found, this will probably
cause a linking failure
project1.lpr(22) Warning: "crtn.o" not found, this will probably cause
a linking failure
Project "project1" successfully built

But surfing on the net didn't give me any good solution. Have any any
idea how to solve this?

Regards, Matija

Hello!

I install Linux Debian on new machine and also install CodeTyphon with
cross compile to ARM.
I made the same program as above and on Linux was working OK, when I
cross compile to arm and run it on Raspberry PI I get the same
problem.
Label1 and Label2 disappere where I press Button1 and reappere when I
press Button2. Tha same with Buton2 text.

Does anybody cross compile to Raspberry PI and can manage text size on
Labels or Buttons?
I will be very grateful for any pointing direction to salve my
problem.

Regards,
Matija

Hello,
I did visit this site, but no solution.
Solution that works is that I write program on PC, transfer files to
RPI, compile it there and I have no more problems with label size and
coloring.
