如何将 readline 包含到 Zig 项目中

Question

我正在尝试在我的 Zig 项目中使用 readline。

我设法通过将其添加到构建文件中来使链接器找到它：

    exe.linkLibC();
    exe.addIncludeDir("/usr/local/opt/readline/include");
    exe.addLibPath("/usr/local/opt/readline/lib");

即使它找到了 readline 定义，它似乎也没有“看到”C lib ...

错误：

▶ zig build                         
./src/main.zig:1:18: error: C import failed
const readline = @cImport({
                 ^

我怎样才能让它工作？

似乎问题不在构建文件中，而是在 cImport 中。

我正在这样做：

const readline = @cImport({
    @cInclude("readline/readline.h");
});

由于错误消息抱怨来自 C 的 stdio.h 的内容，我也添加了以下内容：

const readline = @cImport({
    @cInclude("stdio.h");
    @cInclude("readline/readline.h");
});

现在 Zig 构建工作。
