In fact, there are even more simple:
The first approach:
Added directly in the source file:
AMD64_SOURCES = amd64 \ asm.asm # This is the 64's, 32's can be changed I386_SOURCES
But there would not have joined asm.asm SOURCES up.
The second approach:
Create a project directory folder named amd64, which placed compilation of documents,
Then added directly inside the assembler source file.
Note:
If the following conditions:
1> d: \ winddk \ work \ c \ amd64 \ asm.asm (1): error A2039: line too long
1> d: \ winddk \ work \ c \ amd64 \ asm.asm (1): error A2088: END directive required at end of file
google it says is a version of ml.exe problems that may subsequently improved. The solution is:
The system comes with Notepad to open the file, a look at the source code is only one line. Note: use other editing tools are good.
Solution: In Notepad formatting code inside hand on ok!
