mtpcpu cannot compile in win64
« on: January 08, 2012, 02:01:19 am »
I am using Lazarus v0.9.30.2 Windows 64 bits in Windows 7 64 bit

Lazarus complain "mtpcpu.pas(53,87) Error: Call by var for arg no. 3 has to match exactly: Got "LongWord" expected "QWord""

Here is solution:
function GetSystemThreadCount: integer;
// returns a good default for the number of threads on this system
{$IF defined(windows)}
//returns total number of processors available to system including logical hyperthreaded processors
var
  i: Integer;
  ProcessAffinityMask, SystemAffinityMask: DWORD; <---

Change to

{$IF defined(win64)}
    ProcessAffinityMask, SystemAffinityMask: QWORD;
  {$Else}
    ProcessAffinityMask, SystemAffinityMask: DWORD;
  {$Endif}
