[helpwanted] Compile Errors of libcephei

[Liam0205]

Hi @kirb ,

I'm a tweak developer, and now I want to derootify my previous tweaks that are depending on libcephei. I've noticed that libcephei is now with rootless support (but under testing...), thus the compilling.

Installed lates patched sdks, make gives the following error report. Would you please have a look and any clues to fix this would be appreciated.

You need a newer version of the Swift toolchain - the one you’re using doesn’t support async/await and Task. It was introduced in Swift 5.5.

[Liam0205]

@kirb Thanks for your reply.

I ran xcrun swift --version, and it gives

swift-driver version: 1.62.15 Apple Swift version 5.7.2 (swiftlang-5.7.2.135.5 clang-1400.0.29.51)
Target: x86_64-apple-macosx12.0

It seems that, I already have Swift 5.7.2 with XCode (14.2).

Is it possible that despite having Xcode 14.2 installed on my Mac with Swift version 5.7.2, the correct version was not used when building libcephei?

How can I troubleshoot this issue?

[kirb]

Which SDK are you using? It’ll also need to be iOS 15 or newer. I’m using Xcode 14.2/Swift 5.7.2 and iOS 16.2 SDK.

[Liam0205]

Which SDK are you using? It’ll also need to be iOS 15 or newer. I’m using Xcode 14.2/Swift 5.7.2 and iOS 16.2 SDK.

Well, nevermind.

iPhoneOS16.0b4.sdk is used, and this CE is gone. Now, it comes:

cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64/generated/Cephei-Swift.h: No such file or directory

This could be fixed by #58. And after the fix, it comes:

cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64/Cephei.swiftdoc: No such file or directory
cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64/Cephei.swiftmodule: No such file or directory
cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64/Cephei.abi.json: No such file or directory
cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64e/Cephei.swiftdoc: No such file or directory
cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64e/Cephei.swiftmodule: No such file or directory
cp: /Users/Liam/iOSdev/libcephei/.theos/obj/debug/arm64e/Cephei.abi.json: No such file or directory

It seems that recent modifications have been made to the Makefile and the directory structure of the project, resulting in these issues. It might be more appropriate for me to compile and test the project again once you have resolved them.

[kirb]

Are you using the Theos orion branch? Those files aren’t emitted on the master branch currently.

[Liam0205]

Yes, I'm compiling libcephei with the main branch, and orion branch of THEOS is used:

Sorry, I'm actually on master of THEOS.

Now, when I switched THEOS to the orion branch and ran gmake clean; gmake SYSROOT=$THEOS/sdks/iPhoneOS15.5.sdk, the error has changed:

ListController+Actions.swift:4:8: error: no such module 'MobileIcons'

This is strange because the MobileIcons is actually present in $THEOS/sdks/iPhoneOS15.5.sdk:

Liam@❤️  [15:45:40]:~/opt/theos/sdks/iPhoneOS15.5.sdk
$ find . | grep MobileIcons
./System/Library/PrivateFrameworks/MobileIcons.framework
./System/Library/PrivateFrameworks/MobileIcons.framework/MobileIcons.tbd

I’ll need to push the header changes I made shortly, although the changes are pretty minimal:

+- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier specifier:(PSSpecifier *)specifier NS_DESIGNATED_INITIALIZER;
