addpkg: flclash

该应用编译后可以运行，但是在主页面一直显示核心服务无法连接。ps 命令可以看到两个进程都正常启动：

ps -e | grep Fl
1544050 ?        00:00:02 FlClash
1544267 ?        00:00:00 FlClashCore

对比生成的 FlClashCore，相较于aur中的flclash-bin，稍微大了一些。

namcap 运行输出如下：

#4642

[dongfengweixiao]

将源码来源从压缩包改为使用git编译后，内核工作了。

[dongfengweixiao]

core不支持在CGO_ENABLED为1时构建linux产物，因此保留CGO_ENABLED为0。
在该基础上添加了GOFLAGS="-buildmode=pie -trimpath -mod=readonly -modcacherw"，同时删除了-ldflags="-w -s"。

namcap指出的implicitly satisfied的dependency请显式依赖，避免之后间接依赖关系被破坏导致无法正常工作

libgcc/glibc/glib2/libstdc++属于core，不写入PKGBUILD
fontconfig/cairo/at-spi2-core/pango/libepoxy属于extra，写入PKGBUILD

意向如何？

[lilydjwg]

libgcc/glibc/glib2/libstdc++属于core，不写入PKGBUILD

啊？core又不是base——你把整个core仓库里的软件包都装上了吗？

了解。我会提交修改，将所有的implicitly satisfied dependency都写入到 PKGBUILD。

不过我有一个疑问，linux下的flutter应用的外壳是使用的gtk3，gtk3依赖了
at-spi2-core/cairo/fontconfig/glib2/glibc/libepoxy/pango
那是不是在flutter的PKGBUILD中这些依赖就不需要再包含了？

应当全部显式依赖，现在gtk3依赖了他们不代表以后会依赖。

[dongfengweixiao]

最新的提交，删除了source中git子模块的branch，prepare阶段设置子模块的命令参考wiki重写了以保持与文档的一致。

这个编译错误是已知的，很久以前我就已经提交了一个补丁，但是作者没有合并：leanflutter/hotkey_manager#69

我的家目录下的.pub-cache之前修改过，所以之前编译的时候没有提示该错误。
新的提交增加了patch，prepare阶段通过pub get之后，将hotkey_manager的修改写入。

[dongfengweixiao]

经考虑，使用补丁修改pub-cache下的文件虽然可行，但是太奇怪了。
遂采用dependency_overrides的形式，使用本地的hotkey_manager作为依赖，直接修改本地的hotkey_manager源码，避免修改pub-cache下的文件。
如果hotkey_manager将来解决了该问题，再将相关补丁删除。
