In this tutorial,

> **[Creating a built-in application in Go | Tendermint Core](https://docs.tendermint.com/master/tutorials/go-built-in.html)**

  
The KVStore app cannot be built. The errors are:

go build  
\*KVStoreApplication does not implement “[github.com/tendermint/tendermint/abci/types](http://github.com/tendermint/tendermint/abci/types)”.Application (missing ApplySnapshotChunk method)

I google for 1 hour. I don’t know what is wrong with the tendermint tutorial

Anyone ? It seems that very few people are using tendermint built in app.

I have figured out the problem. The app.go has to implement the missing ApplySnapshotChunk method.

Well. The tendermint core document is obsolete.

Thank you very much. I was comparing my code with yours and found that the ApplySnapshotChunk method was already implemented from tendermint tutorial and noticed that it was not having the SetOptions method.

Thank you, 🙂
