无法识别的链接开关？

[aznarble]

程序中需要使用到大于2G内存空间的功能及API函数，结果在编译时加入了/LARGEADDRESSAWARE时VC无法识别这个链接开关（在Project/Setting/Link/General中的Option中加入），请问是何原因？

错误信息：
Linking...
LINK : warning LNK4044: unrecognized option "LARGEADDRESSWARE"; ignored

环境
Windows 2000, Service Pack 2
Visual C++ 6.0, Service Pack 5, Platform SDK 2296.1

与函数无关，在任何一个工程中加入，都无法识别这个开关。

有这个编译开关吗？
我觉得你理解错了。这看上去应该是一个预定义的宏。如果是这样，在你的程序开头加上
#define LARGEADDRESSWARE
或者
#define LARGEADDRESSWARE 1
就可以了。

当然有这个编译开关，MSDN原文。

Linker Reference
Home | Overview | How Do I | FAQ | Details

LINK is a 32-bit tool that links Common Object File Format (COFF) object files and libraries to create a 32-bit executable (.EXE) file or dynamic-link library (DLL).

Following is a comprehensive list of options for LINK.EXE. For information on how to specify an option, see Set Linker Options.

This section also includes information on Compiler-Controlled LINK Options, LINK Input Files, and LINK Output.

/LARGEADDRESSAWARE Tells the compiler that the application supports addresses larger than two gigabytes.

是使用那个API函数，检查一下这个API函数要求什么版本的操作系统

As far as i know only the win2000 advanced server can run a 3gb user mode program , but in other version it is possible to use this switch, and i test it in my win professional(vc6), and i've not got the linking waring, so the only thing that i can say is making sure your spell is ok.

Oh I think you should add a "A" between "LARGEADDRESS" and "WARE"

MSDN骗人已经不是第一次啦

[houjzs]

use /LARGEADDRESSAWARE

我的运行环境是windows me ; vc6.0 sp5
可以build成功！

哪位知道吗？
加到300分。

拼错啦！LARGEADDRESSAWARE

气死我了，MSDN中的原文居然会少了一个"A"!! (2001年1月版)

On Intel x86 computers with more than 2 GB and less than 4 GB of memory, the GlobalMemoryStatus function will always return 2 GB in the dwTotalPhys member of the MEMORYSTATUS structure. Similarly, if the total available memory is between 2 and 4 GB, the dwAvailPhys member of the MEMORYSTATUS structure will be rounded down to 2 GB. If the executable is linked using the /LARGEADDRESSWARE linker option, then the GlobalMemoryStatus function will return the correct amount of physical memory in both members.
