C语言 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

我设法使链接器找到它添加到构建文件:

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

尽管它找到了readline定义，但它似乎没有"看到"。

错误:

▶ zig build                         
./src/main.zig:1:18: error: C import failed

我怎样才能使它工作?

Answer 1

似乎问题不在构建文件中，而是在cImport.

我在做这个:

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

由于错误消息抱怨来自C的studio .h的东西，我也添加了:

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

现在Zig构建工作了。
