Very strange:

bernd at t40:~/lazsvn/lazarus/trunk\ $ make useride
./lazbuild --lazarusdir=. --build-ide=
primary config path: /home/bernd/.lazarus
TPkgManager.OnGetBuildMacroValues Error: Error: (3,17) operator

// LCLWidgetType
if undefined(LCLWidgetType) then begin
  if GetIDEValue('OS')=TargetOS then begin
    // use the same widgettype as the IDE
    LCLWidgetType := GetIDEValue('LCLWidgetType');
    if LCLWidgetType='nogui' then
      LCLWidgetType:='';
  end;
  if LCLWidgetType='' then begin
    if (TargetOS='win32') or (TargetOS='win64') then
      LCLWidgetType := 'win32'
    else if TargetOS='wince' then
      LCLWidgetType := 'wince'
    else if TargetOS='darwin' then
      LCLWidgetType := 'carbon'
    else
      LCLWidgetType:='gtk2';
  end;
end;

and thousand more lines follow.

Then it continues to build everything, including the IDE. Did I mess up something? I cannot find anything suspicious in the "build lazarus" settings and also nothing in the lazarus project file. What can be the cause of this?

This code is in the file lcl/interfaces/lcl.lpk embedded in the xml. I tried many old revisions of this file but it has been there all the time. Is this intentional?

Found it: My lazbuild was too old. I was too lazy to rebuild it after every svn up.

i wouldn't call it "lazy" but maybe a lack of attention ;) i made it a point to bring stuff like this up with the recent lazbuild work that was done ;)

FWIW: here's my current base build flow ;)

make clean
svn up
make lazbuild lcl ideintf basecomponents starter
lazbuild.exe --build-ide= --build-mode="debug ide"
