Compiling the Chipyard fails

[jordankrim]

I am trying to compile the Chipyard (make -f Makefile.chipyard) with the CEP v4.5. I had successfully done this several weeks ago, but now I am getting an error message:

Can you clarify what has changed in your environment over the last few weeks? It seems from the first few errors that there is some array you recently added which is breaking the compilation,

[jordankrim]

I am having difficulty determining what I may have changed to initiate this. I am on a branch so I don't think I have (or can?) update from the head. Is there any way to chase what got changed and is causing the issue from the messages in the log rather than visa versa?

Through git, you can do many things.. some of them bad. Assuming your internal repository has a github-like interface, you should be able to check your current commit vs the former commit. I'd recommend working with your colleagues to track that down.

A related question: Did anything about the machine you are working on change? Package updates by IT?
