Hi Lucas, With Swift there is a required standard dylib that must be included (and Xcode copies by default). So perhaps CMake should automatically add the rpath option to the Xcode command line?

And this is what you achieved with install_name_tool with an additional step. To avoid this additional step, see https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/DynamicLibraries/100-Articles/RunpathDependentLibraries.html or https://stackoverflow.com/questions/42613881/adding-run-time-shared-library-search-path-to-executable-at-compile-time-clang By the way this is not related to Swift at all. Lucas Le 2 mars 2018 à 20:12, Harry Mallon <[email protected]<mailto:[email protected]>> a écrit : Hello all, When making a pure Swift bundle Xcode automatically copies `libswiftCore.dylib` as follows. ``` ./Tests/SwiftOnly/Debug/SwiftOnly.app └── Contents ├── Frameworks │ └── libswiftCore.dylib ├── Info.plist ├── MacOS │ └── SwiftOnly ├── PkgInfo └── Resources └── libswiftRemoteMirror.dylib ``` When I try to run the output I get a dynamic linking error. I can reproduce this by adding MACOSX_BUNDLE to `./Tests/SwiftOnly/CMakeLists.txt` (in the CMake source tree) in `add_executable` and trying to run the result. ``` % ./Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: .../Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly Reason: image not found zsh: abort ./Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly ``` It seems that the rpath should be set to `@loader_path/../Frameworks`. I am not a Swift maestro so not exactly sure on the details of how this works. After running `install_name_tool -add_rpath "@loader_path/../Frameworks" ./Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly` it runs fine. Does anyone have any idea what to do? Is it a missing CMake Swift feature? We are currently working around it by manually adding the rpath with a cmake step.
