第一个基板链构建失败

Question

想要根据他们的指导[1]一步一步地创建我的第一个衬底链：https://substrate.dev/docs/en/tutorials/create-your-first-substrate-chain/

运行以下命令：货物构建--发布但是得到这个错误：

Answer 1

在基于arch的linux中，您需要以下前提条件：

导出OPENSSL_LIB_DIR＝"/usr/lib/openssl-1.0"；

export OPENSS_INCLUDE_DIR＝"/usr/include/openssl-1.0"；

对于其他oses，请查看/docs/srust-setup.md

Answer 2

WASM_BUILD_TOOLCHAIN=nightly-x86_64-unknown-linux-gnu cargo build --release不需要包括WASM夜间工具链，这可能是基板v2.0所需要的，但基板v3.0 不再需要

请遵循此处的指南并构建[节点模板v3.0:

git clone -b v3.0.0 --depth 1 https://github.com/substrate-developer-hub/substrate-node-template
cd substrate-node-template
# NOTE: you should always use the `--release` flag
cargo build --release
# ^^ this will take a while to do a release build!

Answer 3

尝试使用with parity db功能进行编译，这样就不会编译rocksdb。

如果你想要轻松的生活，那么在checkout目录中运行nixshell，它会安装所有需要的依赖项。
