Hello,

I figured I'd try the "$SetPEFlags IMAGE_FILE_LARGE_ADDRESS_AWARE" in
a program but the compiler isn't liking it.

With FPC v3.0.4, I get the error: Code: Text
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Error:
Identifier not found "IMAGE_FILE_LARGE_ADDRESS_AWARE"
With FPC v3.2.2, I get the error: Code: Text
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Error:
Compile time expression: Wanted Integer but got AnsiString at
SETPEFLAGS
What's the magic incantation to make that option work ?

Thank you for your help.

Hi
This is how I work.
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
{$SetPeFlags $0020}By the way, I want to talk about an interesting
situation.
It works when Code is first added to the unit. Then if the unit is
recompiled without any changes, it doesn't work.

the constant IMAGE_FILE_LARGE_ADDRESS_AWARE is defined in defines.inc,
which is part of the windows unit.
so add the windows unit to your uses clause, then set the flag after
the uses , should work fine.

uses windows, ........

{$SetPeFlags IMAGE_FILE_LARGE_ADDRESS_AWARE}

Thank you loaded and Josh.

I didn't think about the fact that the directive must appear _after_
the Windows unit. 

Thank both again, that was very helpful.

I should have mentioned that in the other thread, but the directives
$SetPEFlags and $SetPEOptFlags either take an integer value, an
integer constant identifier (3.0.x) or an integer constant expression
(which in turn can contain constant values or identifiers) (3.2+). And
the identifiers need to be in scope of course.
