I always get "Fatal: Compilation aborted" error the first time, ...
lazarus / 67-Windows

Hello,

since today, I always get an "Fatal: Compilation aborted" error, when
I compile my project after I did some changes. When I "re-compile" the
project, it compiles fine.

The last days it was just randomly, but since today it's always. Does
anybody know, what the issue is here.

I use generics in delphi mode, maybe that is the issue? I remember
when CodeGear/Emb introduced generics/closuers I had a similar
problem.

Lazarus 1.6
Win7 + 64Bit

Well then, give us some code that reproduces the issue.
If you had similar issues with Delphi, chances are your code "doesn't
meet standards"  .

I will try to isolate the issue. I also use ZeosLib and mORMot in my
project.

right click the message window, and get ALL and Hidden messages. That
may give more info on the error

These are the messages, but don't see any hint, for that issue:

I also tried to use my delphi mode generic code in a new project, but
there it works fine. The only thing I recognized is, that in the
project where the error occuers, the compiler doesn't complain when I
use my generic class the delphi way without declaring that unit as
{$mode delphi}.

e.g.:

var
  x: TSimpleDict<Integer>; //compiles without {$mode delphi}

But adding that compiler mode, doesn't change anything.

I added some more code lines (proceeded with my work), and now the
fatal error is gone.

Strange

my condition:

  if I set the default vale of one var parameter , like this :
 
  function   xSelectSQL( _sql: string; var _ErrMsg:String=''):Boolean;

  then Compilation aborted .

The error message clearly doesn't mention var parameters and that is
logical (it's passed by reference, default value conceptually doesn't
have memory address to be passed as reference).

Thanks !
hu !  so I see .
it's a reference, a memory address, can't be initialized .
