Are you on Apple M1? If, so there are currently issues with building rocksdb there. See here an approach: vikiival.medium.com/run-substrate-on-apple-m1-a2699743fae8 – Showbread

This needs more clarity. What are your dependencies, platform, and more specifically what is the full output of the build error? – Misplace

Answer 1

You need to install additional library:

sudo apt install clang should help.

I have old mac and brew require os version 10.16 while I have 10.14 any solutions for me please – Hardball

The solution works for Linux based OS, I do not know issues with old mac so not able to help. – Ayeshaayin

Answer 2

sudo apt-get update
sudo apt install make clang pkg-config libssl-dev

This should do the trick. Reference: https://github.com/paritytech/polkadot/issues/65

Thanks ! That did the trick for a project I'm working on, in the Solana ecosystem ! – Elsi

Also others have reported needing to:

You need clone the rust-rocksdb repo and checkout the commit listed here: https://github.com/substrate-developer-hub/substrate-node-template/issues/122 then you can create a config.toml file in your .cargo folder in your home directory and add a path to that cloned repo

You had better update cargo to the nightly version and then try it. If it keep in stuck error try comment commands, you may will need to study link.

#rustup component add --toolchain=nightly rust-src rustfmt

rustup target add wasm32-unknown-unknown

#apt-get install llvm clang linux-headers-"$(uname -r)" #

apt install llvm clang
cargo build --release

Answer 5

You need to update the to this version: "6.20.3" checksum = "c309a9d2470844aceb9a4a098cf5286154d20596868b75a6b36357d2bb9ca25d"

This works for me as well, running on macOS. Just updated Cargo.lock file and everything started working perfectly! – Spiritualism

Answer 6

For me, on intel (x86_64-apple-darwin) MacOS, fix was in uninstalling brew installed llvm.

brew uninstall llvm

and using one installed from Apple's Command line tools.

Answer 7

So for me what works was:

sudo apt-get update
sudo apt-get install g++

I tried several things but, after downloading g++ on Ubuntu running WSL2 worked for me and I was able to build and run frontier and run with the following commands:

git clone https://github.com/paritytech/frontier/
cd frontier
cargo build --release
./target/debug/frontier-template-node --dev

And to see the blockchain explorer I used this link https://polkadot.js.org/apps/#?rpc=ws://127.0.0.1:9944
