添加了 SwiftPM 支持，大佬能抽空帮忙看下吗？ @Richard-Cao

合入后可能还得发布一个新版本才行

[Richard-Cao]

@wsxyeah 一起看看

这几个头文件是用的软链接？GitHub diff 上看不太出来

是的，不太想破坏原目录结构，常见的做法是把对应 header 软链到 include 里来满足 Package 要求的 Layout

https://github.com/apple/swift-package-manager/blob/main/Documentation/Usage.md#creating-c-language-targets

cd include
ln -s .../**/*.h ./

配置 publicHeadersPath 应该也可以？

publicHeadersPath 是额外的for search用的，这里讨论的是 include / modulemap layout

我的经验告诉我是不行的，或者您可以尝试下，直接 comment 提供新的 patch

publicHeadersPath 不传就是默认 "include"，用 "." 试过是不行的，因为布局不满足要求

你说的 for search 应该是指 cSettings.headerSearchPath？

我看这个库是用的publicHeadersPath。

参考文档

Nope.

Sorry for the miswording/confustion I cause.

You can have a look at the SwiftPM repo code here

// Compute the path to public headers directory.
let publicHeaderComponent = manifestTarget.publicHeadersPath ?? ClangTarget.defaultPublicHeadersComponent 

public final class ClangTarget: Target {
    /// The default public include directory component.
    public static let defaultPublicHeadersComponent = "include"

publicHeadersPath will be "include" if we do not specific it for ClangTarget.

We still need such layout here.

If you do not provide include folder and try set it to "." things will not work here because the layout is not valid.

我看这个库是用的publicHeadersPath。

If you like, I can add publicHeadersPath: "include" here but that's not the point and unnecessary for most of the case.

Again, if you have any better suggestion or comment, I believe the best way is to communicate via code/patch.

试了下这样写是可以的

另外 .gitignore 需要添加下 .build 目录

Thanks, it works. Maybe there is some strange cache issue for my previous try.
