 Assembling: simple.asm

C:\Users\mahdi\Desktop\New folder>link /subsystem:console /entry:main simple.obj
 io.obj Kernel32.Lib
link: extra operand `simple.obj'
Try `link --help' for more information.

Solution

Although this question was answered by @Michael, I would like to make it clear.

We have to put the CYGWIN path stand behind the MS Visual Studio path.

 Path=....C:\Program Files (x86)\Microsoft Visual Studio\VC98\bin;C:\cygwin\bin

Open Windows command prompt:

cmd
link --help
