Setting up local BTC environment errors

working thru

m1 mac
bitcoin-core running locally
port 8333 is default port … has been running several months without issues
set dfx.json to port above

fails on:

basic_bitcoin % dfx deploy basic_bitcoin --argument ‘(variant { Regtest })’

console log is here

then added command
cargo add secp256k1-sys

been hanging on nostr with our BTCmaxi brothers and what to show this off :slight_smile:

error occurred: Failed to find tool. Is clang installed?

Sounds like a problem with your machine’s setup to me. Can you make sure that clang is available?

same error

this is where things derail

reinstalled llvm and added suggested paths to .zshrc

it compiles now but …

It’s pretty common to have rust canisters be too big. There’s a few things you can try. Probably easiest is cargo install ic-wasm, which will try to remove unused code from the wasm before uploading. Next is to gzip the wasm before uploading it. This requires a custom build script and you should be able to find more info about it in this or this thread.

thanks got things working by compressing wasm and rolling back dfx 12.1. → dfx 12.0

i was not able to install ic-wasm

some issues may be from using a M1 mac
