Delphi 2007 IMAGE_FILE_LARGE_ADDRESS_AWARE

Question

我希望我的應用程序能夠使用2GB以上的內存，我搜索了一下，發現IMAGE_FILE_LARGE_ADDRESS_AWARE命令可以讓我做到這一點。

所以我添加

{$SetPEFlags IMAGE_FILE_LARGE_ADDRESS_AWARE} 

要我的程序的.dpr文件，所有的用途和後{$ R * .RES}行，

但是當我編譯，我得到的錯誤：

E2003 Undeclared identifier: 'IMAGE_FILE_LARGE_ADDRESS_AWARE' 

我在做什麼錯？

此外，在64位Windows 7，我需要有引導設置惹周圍此命令的工作，或者只是編譯命令32位應用程序，它會自動別的做的一切？

感謝

Answer 1

Also, on Windows 7 64bit, do I need to mess around with boot settings for this command to work, or just compile a 32bit application with the command and it will do everything else automatically?

64位Windows會自動提供4 GB的地址空間，而無需啓動調整。

http://msdn.microsoft.com/en-us/library/windows/desktop/bb613473%28v=vs.85%29.aspx：

To enable an application to use the larger address space, set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the image header. The linker included with Microsoft Visual C++ supports the /LARGEADDRESSAWARE switch to set this flag. Setting this flag and then running the application on a system that does not have 4GT support should not affect the application.

On 64-bit editions of Windows, 32-bit applications marked with the IMAGE_FILE_LARGE_ADDRESS_AWARE flag have 4 GB of address space available.

答案的實際問題是添加到使用單位Windows。
