I got the following error on Ubuntu 20.04 by running cargo build --release
Compiling sp-arithmetic v2.0.0-dev (/home/min/Projects/substrate/substrate/primitives/arithmetic)

error: build failed
In master?
@bkchr yeah it's in master. But the same error happens even if I checkout other branches like v2.0.0-alpha.6.
$ git branch -v
* master c82a0f7b5 Remove background_tasks field in ServiceBuilder (#5830)
Which rust version are you using?
$ rustc --version
rustc 1.43.0 (4fb7144ed 2020-04-20)
I am going to get a substrate docker image in case there is something wrong with my local environment...
BTW I tried with another ubuntu 18.04 laptop and same error occurred.
I am having a similar error too.

error: build failed`I am using
rustc 1.47.0 (18bf6b4f0 2020-10-07)
Is the problem solved锛烮 am having the same error too.
i had the same issue and i solved it using the nightly-2020-10-06 compiler version as the documentation says:
https://substrate.dev/docs/en/knowledgebase/getting-started/#webassembly-compilation
Then i run the command setting the env variable WASM_BUILD_TOOLCHAIN:
WASM_BUILD_TOOLCHAIN=nightly-2020-10-06 cargo build
I had the same error
@hbulgarini suggestion fixed it 馃帀
after I changed the wasm target as well
rustup target add wasm32-unknown-unknown --toolchain nightly-2020-10-06
This solves it @manuelpolzhofer
rustup toolchain install nightly-2020-08-23
rustup target add wasm32-unknown-unknown --toolchain nightly-2020-08-23
Then compile your node with this:
cargo +nightly-2020-08-23 build --release
@bkchr I try to build a kitchen node but got:
https://github.com/paritytech/substrate/issues/7150#issuecomment-748978039
There is any place where I can find versions of Rust and toolchains required to build the node?
