[Lazarus] Linker errors
Hi Folks. In a TDaemon project running nicely since beginning of last year, I have added a TTimer to execute periodically an internal control procedure. I then added a TTimer component, the unit ExtCtrls in the uses clause, the code of the TTimer event, compile and ... nothing: linker fails with a lot of errors like these: /usr/bin/ld: warning: /home/sources/compiled/link.res contains output sections; did you forget -T? /home/sita/.lazarus/lib/LCLBase/units/x86_64-linux/wsimglist.o: In function `WSIMGLIST_REGISTERCUSTOMIMAGELIST': wsimglist.pp:(.text+0x99f): undefined reference to `WSRegisterCustomImageList' /home/sita/.lazarus/lib/LCLBase/units/x86_64-linux/wsmenus.o: In function `WSMENUS_REGISTERMENUITEM': wsmenus.pp:(.text+0x167): undefined reference to `WSRegisterMenuItem' /home/sita/.lazarus/lib/LCLBase/units/x86_64-linux/wsmenus.o: In function `WSMENUS_REGISTERMENU': wsmenus.pp:(.text+0x187): undefined reference to `WSRegisterMenu' /home/sita/.lazarus/lib/LCLBase/units/x86_64-linux/wsmenus.o: In function `WSMENUS_REGISTERMAINMENU': wsmenus.pp:(.text+0x1a7): undefined reference to `WSRegisterMainMenu' As you can read the linker references a lot of units located into the local user home directory. I wonder why. The IDE has been rebuilt without problems Installation is a Linux Opensuse 12.2 x86_64, Lazarus 1.0.12, fpc 2.6.2 installed out of rpm's. When I embed all TTimer references into conditional code, no more problem. The daemon compiles and runs as before. BTW, the same project compiles and runs under Win32 with the TTimer (Lazarus 1.0.12 and FPC 2.2.6, same external componets). I think to a workaround solution based on another thread sleeping for the required period of timet this adds some extra useless overhead Any explanation ?

I forgot to be more precise: embedding the same TDaemon code into a normal application using a front end display the code compiles without problems Of courese in this case, the daemon register procedures are conditionally surrounded by IFDEFs and are not compiled under the gui application.

[Lazarus] Compile works, building DEB package fails

[Lazarus] TFPTimer, Linux
Hi Folks.
Following a Michael advice I changed a TTimer by an TFPTime component in
a Linux daemon application but the latter doesn't work.
There is the code snippet of the TFPTime OnTimer event:
procedure TDaemon1.ThreadControlTimerTimer(Sender: TObject);
var
Res: Boolean;
begin
// se réveille toutes les 10 secondes pour vérifier l'état du thread
FLog.Add(9, '1', esError);
try
FLog.Add(9, '2', esError);
except
on E: Exception do begin
FLog.Error(Format('+++ error on log control thread:%s',
[E.Message]));
Res := False;
end;
end;
FLog.Add(9, '3', esError);
try
FLog.Add(9, '4', esError); - this line appears
into the log file
ThreadControlTimer.Enabled := False;
FLog.Add(9, '5', esError); === this line is never reached
Res := DoThreadControl;
FLog.Add(9, '6', esError);
except
on E: Exception do begin
FLog.Error(Format('+++ error on control thread:%s', [E.Message]));
Res := False;
end;
end;
if Res then begin
FLog.Add(9, '7 True', esError);
ThreadControlTimer.Enabled := True;
end else begin
FLog.Add(9, '8 False', esError);
end;
end;
It looks like the Enabled property doesn't work and blocks the TFPTimer
in some way. The event is fired on time, but only once and never more.
I'dl be glad to know what happens.
Antonio.

DaemonApp works using threads.
TFPTimer is not usable in threads other than the main thread.

I think is much better change the default behavior to generate a external debug file but i don't know if it has any consequence... 2014/1/15 Martin laza...@mfriebe.de On 15/01/2014 10:43, Kostas Michalopoulos wrote: Is it really necessary to mention exe size in the Windows installer?
