Quartus II 4.0 - Start Complilation Disabled

It came with a book that is why I used that version. But latter I installed latest version as can be seen below. In the second image I have the same problem.

I installed Quartus II 4.0 on VMware Workstation running Windows XP Pro SP3, here also I have the same issue.

Have you created a project, or just opened the VHDL files?

You need a project to be able to compile.

BTW: if thats the code that came with the book (johns.vhd) - I would ditch that book and find one that uses much better code examples (the code is quite poor).

Thanks, that was exactly it, I needed to create a project first. I was able to compile the file. Regarding, johns.vhd, the code is definitely written poorly but it is not from the book, I found it online.

Now that I compiled the file I want to do a functional simulation where I face another problem, as seen below. I searched for that error and one suggested to add file to the top-level. But it is already in top level. Any ideas what is going on?

Hi thebatosai,

Sorry if I have missed out anything. What is the error with compilation that you are encountering? I mean the Quartus II error message.
