Got error "linking with rust-lld failed: exit code: 1" when compiling contracts in examples

arookie · July 15, 2019, 10:24am

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.

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?

hey guys, any updates on this one? Please help me.

@adi can you pls take a look

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 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:

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?
Error logs:

Please help!

looking into this @arookie , hopefully will have something for you shortly!

arookie · July 23, 2019, 2:47am

hi @adi, any lucks on this one?

adi · July 23, 2019, 3:10pm

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!

arookie · July 24, 2019, 2:03pm

hi @adi, will get in touch with you tomorrow. I have sth need to be done today and back to Enigma tmr.

izokay · July 27, 2019, 1:00am

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

arookie · July 26, 2019, 3:26am

hi @izokay, i got that issue even though I compile the example contracts.
Btw, I will try your solution tonight.

arookie · July 28, 2019, 3:49am

hi @adi, i found some information here & here relating to my issue.

I already dm you on Discord, if you have time, can you please help?

Thank you.

ainsley · July 29, 2019, 7:49am

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.

arookie · July 29, 2019, 10:00am

hi @ainsley, yes. I met the issue with discovery-cli and using sw mode.

adi · July 29, 2019, 12:01pm

Being handled offline at the moment, but will post findings to help others running into similar presetup issues

bmiller59 · December 22, 2019, 11:24pm

@adi @arookie Any notes on the resolution of this issue? I seem to be encountering something similar. Thank you.

bmiller59 · December 27, 2019, 8:09pm

If anyone else comes onto this thread looking for the resolution, this post from above helped me to resolve my issue: Got error "linking with rust-lld failed: exit code: 1" when compiling contracts in examples

I had to set the name field in my Cargo.toml to be contract. Creating a custom contract name causes the build to fail.

@taariq or @ainsley I recommend that be documented in the sample Cargo.toml files so people don’t change it!

taariq · December 28, 2019, 4:44am

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?

My rustc version is 1.39.0, what’s yours?
