先决条件

安装 Xcode 和 Homebrew。然后，使用以下命令安装所需的软件包：

brew install git cmake ninja

构建 DuckDB

克隆并构建 DuckDB，操作如下。

git clone https://github.com/duckdb/duckdb
cd duckdb
GEN=ninja make

构建成功后，您可以在 build 目录中找到 duckdb 二进制文件

build/release/duckdb

对于不同的构建配置（如 debug, relassert 等），请参阅构建配置页面。

故障排除

构建失败：未找到文件 'string'

问题：在 macOS 上构建失败，并出现以下错误：

解决方案：用户反馈重新安装 Xcode 解决了他们的问题。请参阅 DuckDB GitHub issues 和 Stack Overflow 上的相关讨论。

警告：尝试重新安装 Xcode 套件可能会影响您系统上的其他应用程序。请谨慎操作。

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Debug 构建打印 malloc 警告

问题：macOS 上的 debug 构建打印 malloc 警告，例如：

duckdb(83082,0x205b30240) malloc: nano zone abandoned due to inability to reserve vm space.

解决方案：为防止此问题，请将 MallocNanoZone 标志设置为 0

MallocNanoZone=0 make debug

要将此更改应用于您未来的终端会话，您可以将以下内容添加到您的 ~/.zshrc 文件中

export MallocNanoZone=0
