Hi guys, When compiling the `simple_calculator` contract, it seems that it cannot generate `contract.wasm` because of this error “linking with `rust-lld` failed: exit code: 1” (The same error happens when I compiled the other examples). You can check full error logs [here](https://forum.scrt.network/t/error-installing-discovery-cli/917/25). And I tried some ways to rebuild it, such as add option linker “RUSTFLAGS=’-C linker=rust-lld’ cargo build --release --target wasm32-unknown-unknown --verbose” when recompiling it , but still got same error. Can you please take a look? ---

> [@arookie](#): > > linking with `rust-lld` failed: exit code: 1 Hey @arookie! Looking into this, unable to reproduce on my end at the moment, so will continue digging. From the looks of it, it seems like you are building things more manually. Have you tried using the `discovery-cli` to compile the `simple_calculator` and other example contracts. That’s our recommended way of playing around with the examples and writing your own secret contracts, and I don’t believe there should be an issue with that at the moment…but let me know if you see otherwise! ---

hi @adi I already got [the issue](https://forum.scrt.network/t/error-installing-discovery-cli/917/25) when installing `discovery-cli`, so I used the docker to build instead. I will try to rebuild the brand-new env and let you know the result later. Btw, for `discovery-cli`, I tried to downgrade node version to v10 and it’s working now. ---

Hey @arookie! Been spending a fair amount of time on this and can’t reproduce, I believe these are all corollary issues to your initial setup (node, etc.). I think what’s best is if we start a private chat (via discord, feel free to DM me (@Adi#6679) to have more streamlined communication. I’ll draft up a initial setup post after we resolve your issue to help guide others that may run into similar problems in the future! ---

I got a similar error compiling a contract. In my case I found deps.js looks for contract.wasm but `secret_contracts/{CONTRACT_NAME}/target/wasm32-unknown-unknown/release/contract.wasm` was named `secret_contracts/{CONTRACT_NAME}/target/wasm32-unknown-unknown/release/{CONTRACT_NAME}.wasm` fixed by manually renaming to contract.wasm and recompiling. Maybe this isn’t the right solution but it compiled 🙂 … happens if you don’t change the name in Cargo.toml file ---

Hey @izokay and @arookie – can you confirm that you’re building using the CLI and in SW mode? At this time we can only support issues that arise in a controlled developer environment so it’s important that the setup is consistent. ---
