Can I build a 64bit with "NMAKE"

I'm making 64bit program now.I use the VC6.0 and MS PSDK,because I have some Fortran codes,so I want use "NMAKE" to build my program. I got a makefile from VC6.0,but I got some errors.
I make a simple project with VC6.0, I can get a well 64bit program use the "build" command in VC6.0,but I still got errors when I using the "NMAKE" command.
Why?
Nmake should work fine targeting any type of processor. Can you show a snippet of the makefile and the error you are getting?
And just to be clear, you're using nmake from VC6. How did you create the makefile? By hand or autogenerated?

thank you.
Kang Su GatlinI have worked my problem out. I have a good makefile now,and I got my 64bit program.But I had a new program is that how can I debug it ?
I create my makefile by autogenerated,and change some things in it by hand.
To debug a 64bit program you need to have Visual Studio 2005 or use WinDbg for 64bit. Those are the two options you have for debugging.
