64 bit compilation on 32 bit intel machines

[tsrmohan]

Can I create 64 bit dlls for Windos XP on a 32 bit machine?
What compiler should I use for this ?

Mohan,

We are building our 64 bit components for WinXP.
With MS compiler, first install the SDK from MS.

Then produce the makefile from your 32 bit project (Project -> "Export Makefile" with MS VS 6.0)
Then:
SetEnv.Bat /pre64 /RETAIL
nmake /f your_makefile.mak" "YourProjectName - Win32 Release" CLEAN
nmake /f your_makefile.mak" "YourProjectName - Win32 Release"

I have no experience with Intel compiler, but in the past there was also an opportunity for sure to make cross compilation also.

Hello Daniel,
- I have installed MS SDK on a Windows 2000 machine.
- I am using the cl.exe to compile the cpp files.
- When i use the link.exe with /Machine:IA64 option i am get the following error:
DllTest.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'IA64'

Which means that the obj's that are created X86 compatible. What option can I specify to get IA64 compatible obj's?

Thanks,
Mohan

You must use cl.exe & link.exe from SDK located in Binwin64 folder.
Use WIN64 define (/D"WIN64") when you produce .obj from .c

Mohan,

I believe that "SetEnv.Bat /pre64 /RETAIL"
sets all needed pathes, so you should not run into troubles after running it.
