OK, I am back with the resolution for my issue.
Turns out my issue was not related to neither of linked thread, but I found solution in the latter thread. I have uploaded a repo containing my example GitHub - mikolasstuchlik/LldbMinimalTest.
I've tried following steps:
- Clean the project using
swift package clean - Build debug using
swift build - Run my LLDB using
/my/path/to/swift/from/swift-org/usr/bin/lldb .build/debug/LldbMinimalTest - Add breakpoint using
breakpoint set --file main.swift --line 1
If any error ocurred when I set the breakpoint, I've tried another solution.
Turns out, that when target CGLib (which is system module) was added as a dependency directly to the executable target, lldb worked correctly. When I adeed CGLib as a dependency to a Swift target GLib and then added the target GLib as a dependency to the executable target, lldb failed.
I've configured LLDB according to Adrian's post and determined, that my issue was of a different nature than that of the OP of the thread.
Therefore I tried to call swift build with flags for frontend as described by Anthony and this solved my issue.
As I stated in the post above, my error message was exactly the same as yours, maybe the solution is worth trying for you aswell.
I have finalized my solution by addidng swiftSettings: [.unsafeFlags(["-Xfrontend", "-serialize-debugging-options"], .when(configuration: .debug))] argument to the (swift) GLib target which has CGLib as a direct dependency.
Hope this will help
