no rule to make target

I trying to use openlb for the first time and I am having trouble using the example codes to see if it works. I believe I gave the correct directories and configured the files to run but I keep getting the same error " no rule to make target." I am currently using cygwin on window vista home basic system. Any help you can give would be greatly appreciated. Thanks

Is this the full error message, or is there more output? If it is the full message, this simply means that there is not Makefile in the current directory. Which means that you are not in an example directory. Solution: switch to an example directory, as in

cd examples/cavity2d/

and then type “make”.

Hope this helps,
