Hi,
I wrote a small program for Linux in a previous version of Lazarus
which compiled and ran without problems before. I have now updated to
fpc 3.0.0 and Lazarus 1.6 (backports version for Debian X86_64
Jessie). The code still compiles perfectly (it had a number of
warnings, but these have now disappeared: e.g. unixfileutil.inc(6,51)
Warning: Symbol "UTF8ToSys" is deprecated: "Use the function in
LazUTF8 unit"), but it results in a runtime error
"Project birds raised exception class 'External: SIGFPE'.
At address 7FFFEF8FC57F"
when running the following code:
procedure THoofVrm.OpenBtnClick(Sender: TObject);
begin
OpenDlg.Execute;
end;
What is wrong with my code (and how should I change it)?
I know that there has been a change in FPC/Lazarus string
implementation, but this is just a standard Lazarus File Open dialog
(TOpenDialog) and result in the error before even allowing me to
select the file to open.
I am not using either UTF8ToSys or even the unixfileutil unit AFAICT:
"uses
Classes, SysUtils, FileUtil, LResources, Forms, Controls, Graphics,
Dialogs,
IpHtml, StdCtrls, ExtCtrls, Buttons, ExtDlgs, AsyncProcess,
Ipfilebroker,
strutils, Soek;"
Any pointers appreciated...
Regards,
Chavoux
Just a wild guess. The villain might be some property (such as FileName,
Filter or InitialDir) that you did set up with old Lazarus at design
time and which isn't compatible with current version. Revising the
design time properties of your File Open Dialog with Object Inspector
should fix the issue.
