You don't say what tool you're using, whether you're trying to do
simulation or synthesis, and whether you've written oc8051_alu_test.v
yourself, or if you got it someplace, where and whether you've modified
it.

That error message indicates that something called "oc8051_alu" is being
declared twice. Have you looked through that file to see if it's
happening within the file?

You're attempting to use a macro that doesn't exist. If you wrote the
code, then you probably misspelled the macro either where you define it
or where you use it. If you didn't write the code, tell us where you got
it.

If you're trying to make an 8051 core work and this level of problem
stymies you, you have a long row to hoe.

First, if you're using Xilinx tools I would suggest moving your project
to a directory that has no spaces in the path like c:\projects

Second, I suspect that although you're only seeing 2 errors, there must
be piles or warnings that would probably shed light on the real issue.
For example your second error saying that a Verilog macro is not defined
often means that some `include file was not found and therefore you
missed out on all of the `defines in that included file. This often
happens in the Xilinx tools if you don't tell it where to look for
included files or put a more complete path in the `include statement.

It seems oc8051_alu_test.v and oc8051_alu.v define the same module inside so you probably want only one of them. It seems like alu_test is a new module in development. Try running the scripts in the sim directory instead of trying to make your own tests.
