Hi,

I got a linker error while installing dlcodac10.lpk in Lazarus IDE under Linux 32 bit enviroment - I use OpenSuSe 11.4 and also Ubuntu 10.04.3 / FPC 2.4.2 and also 2.4.0 / Lazarus 0.9.30 :
- Compiling of package is OK, without any error message but
- Installing ends up with following messages:

I try the same with ODAC version 6.90 without any error - at this time I have no password for ODAC source code version 7 ...

Hello,

Thank you for the information, we have reproduced and fixed the problem.
This fix will be included in the next product version.
For the time being you should make the following changes in the MemUtils.pas file:

add the {$IFNDEF FPC} directory in the 688 line and {$ENDIF} in the 697 line;

Code: Select all

{$IFNDEF FPC} - add
function PtrOffset(Value: IntPtr; Offset: Int64): IntPtr;
begin
{$IFDEF CLR}
  Result := IntPtr(Value.ToInt64 + Offset);
{$ELSE}
  Result := IntPtr(Int64(Value) + Offset);
{$ENDIF}
end;                                       
{$ENDIF} - add
