合约编译

使用Remix方式

打开已经写好.sol文件 -> 选择左边栏Solidity Compiler -> 点击按钮Compile XXX.sol（或者在合约编辑框按快捷键 command+s 也可以自动编译合约）

编译好之后，在左边栏可以点击复制ABI和合约bin文件的内容（可用于用vcl部署合约，若使用Remix部署合约则无需复制ABI和Bytecode）：

注意，Bytecode按钮生成的内容如下：

在生成bin文件时，只需要复制"object"项的值，bin文件内容形如：

使用vcl方式

在前面章节已经介绍了如何安装solidity的命令行编译器solc。该编译器可以生成各种输出，范围从简单的二进制文件、汇编文件到用于估计 gas 使用情况的抽象语法树（解析树）。

使用如下命令来查看它的所有选项的解释：

solc --help

使用如下命令可以在 Storage_output 文件夹中生成二进制bin文件和abi文件：

solc --bin --abi -o Storage_output Storage.sol

使用truffle方式

如果使用 安装方式一：直接安装 安装truffle的，那么

# 在合约项目的根目录下执行
truffle compile

如果使用 安装方式二：源码编译 安装truffle的，那么

# 在合约项目的根目录下执行
yarn run truffle compile
