请求添加 mac catalyst 的支持

[CaffreySun]

你在什么场景下需要该功能？

我有个动态库 framework 需要适配 mac catalyst。
mac catalyst的介绍：https://developer.apple.com/cn/mac-catalyst

我现在使用 option 实现了 mac catalyst 库的编译

set_languages("c++14")
add_rules("mode.debug", "mode.release")

option("mac_catalyst")
    set_default(false)
    set_showmenu(true)
    set_description("是否编译 mac catalyst")
    add_cxxflags("-target x86_64-apple-ios13.1-macabi")
    add_shflags("-target x86_64-apple-ios13.1-macabi")
option_end()

target("MyLibrary")
    add_options("mac_catalyst")
    add_rules("xcode.framework")
    set_kind("shared")
    add_files("src/*.cpp")
    add_files("src/Info.plist")

然后

xmake f -p macosx -a arm64 -m release --mac_catalyst=y
xmake

但是这样有问题：

1. 用编译出的framework不能使用，使用时会报错Library not loaded: @rpath/MyLibrary
2. 想要修改option中的x86_64-apple-ios13.1-macabi中的ios13.1版本就比较麻烦。
3. ios13.1其实是iphoneos的版本号，而在macosx平台下只能设置mac的sdk版本号。

描述可能的解决方案

一、在 macosx 平台下修改

在 xmake config 中增加 mac catalyst 配置项，
然后根据配置把load_macosx.lua文件中的
format("-target %s-apple-macosx%s", arch, target_minver)
改为
format("-target %s-apple-ios%s", arch, target_minver)。
但这里有一个麻烦点，现在target_minver是macos的版本，需要改为对应的ios版本，
并且 mac catalyst 最低支持ios13.1。
还有就是Library not loaded: @rpath/MyLibrary报错不知道该怎么处理。

二、在 iphoneos 平台下修改

在 xmake config 中增加 mac catalyst 配置项，
然后在find_xcode.lua中判断如果plat == "iphoneos"并且是 mac catalyst时，
将platsdkdir改为macos的sdk路径：
platsdkdir = "Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX*.*.sdk"
但是有一个注意点，在load_iphoneos.lua中设置format("-target %s-apple-ios%s", arch, target_minver)时，target_minver最低支持13.1

试下这个 patch #2695

xmake update -s github:xmake-io/xmake#catalyst

[waruqi]

还是有点问题，编译器要用 xcrun -sdk iphoneos clang 还是 xcrun -sdk macosx clang?

xmake f -p iphoneos -a x86_64 --appledev=catalyst

[CaffreySun]

sdk 使用 macosx

[waruqi]

好了，再试试

xmake update -s dev
xmake f --appledev=catalyst -c
xmake

现在可以编译，但是使用编译出的Framework时会报错

在使用xmake -v 编译时，看到输出 -install_name @rpath/RbtBezie，我用xcode工程编译的时候能看到输出-install_name @rpath/RbtBezierLib.framework/Versions/A/RbtBezier，是不是这个区别导致了Library not loaded: @rpath/RbtBezier 报错。

不清楚，不过我刚修了点其他的问题，storyboard 编译，和 UIKit 的支持等等。。

https://github.com/xmake-io/xmake/tree/master/tests/projects/objc/iosapp_with_framework

我用这个带 framework 的例子测试，是可以正常编译和加载 framework的。。

$ xmake update -s dev
$ cd iosapp_with_framework
$ xmake f --appledev=catalyst -c
$ xmake
$ xmake run
2022-08-22 10:29:37.074 demo[78404:5225667] add(1, 2): 3
2022-08-22 10:29:37.074 demo[78404:5225667] hello xmake!

我把iosapp_with_framework编译出来的test.framework放到一个新建的xcode工程里，就会报错：
dyld[34419]: Library not loaded: @rpath/test

iosapp_with_framework 使用 xmake f --appledev=catalyst -c 编译出来的demo.app的目录结构和xcode不太一样
xcode编译出来的app目录结构：

• Demo.app
  • Contents
    • MacOS
      • demo
    • Frameworks
      • test.framework

xmake编译出来的app目录

• Demo.app
  • Contents
    • MacOS
      • demo
      • test

所以xmake run可以运行起来，因为test和demo在一个目录下，@rpath/test 能找到test

依赖的 frameworks copy 到 .app 一直还没搞，TODO 状态，之前只是临时性 copy 了 dylib 过去

xmake/xmake/rules/xcode/application/build.lua

Lines 49 to 54 in b359ad6

	-- copy dependent dynamic libraries, TODO copy frameworks
	for _, dep in ipairs(target:orderdeps()) do
	if dep:kind() == "shared" then
	os.vcp(dep:targetfile(), binarydir)
	end
	end

好的，辛苦了大佬

[waruqi]

可以了，你再更新到 dev 试试

👍确实可以了，大佬辛苦了
