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).
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.
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 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.
hi @adi, can you please help to take a look? Once again, I still cannot compile the contract millionaires_problem, I just followed the 2nd part of dev guide.
After I run discovery compile -s ASSERTIONS=1, it gave me a bunch of errors which I’m gonna show below:

Something went wrong compiling secret contract millionaires_problem, aborting.

And it also relates to linking with rust-lld issue which I reported few days ago.
Can you please take a closer look and give me advice?
hi @adi, if I run cargo +nightly run, I cannot compile the eng-wasm
How can it happen?

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!
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.
Hmmm, just tried this and it compiled with any package name.
I copied one of the examples into a new project and renamed the package in Cargo.toml, did i miss something?
and back to Enigma tmr.
