Now getting bunch of errors, and the hint message not helpful as I've just ran anchor build.

Needless to say, stating the obvious: first initial experience of using framework matters, if I struggle on a fresh install, non-zero chance others are affected too 🙏

Error: target/idl/solana_encode_homework_11_fresh.json doesn't exist. Did you run `anchor build`?

The error message is not great — we should definitely improve it. The reason for the error is the case conversion of numbers, which was explained in #3353 (comment).

Essentially, you named your program solana-encode-homework11-fresh, and during the case conversion from camelCase, it assumes as if there was a - before the 11. Here are some ways you can fix this:

• Rename the program to have - before 11, e.g. solana-encode-homework-11-fresh
• Rename the IDL file in target/idl to be solana_encode_homework_11_fresh.json
• Avoid having numbers in program names

Related: The warnings related to "unexpected cfg condition value" has been fixed in #3396.

We should prioritize fixing this, especially given it's been reported multiple times now.

Thanks for creating the issue, but I'm closing this as duplicate of #3353 to not divert attention.
