 Randy Eckenrode | I get that crash when building swift-corelibs-xctest for Swift Driver. 😕 | 02:02:28 |
| Randy Eckenrode | I think I got the SDK propagation wrong. | 02:08:35 |
| Randy Eckenrode | So close. SwiftPM depends on Swift Driver. I guess I’m going to have stick with the CMake build of Swift Driver. I don’t like that. | 02:45:54 |
| Randy Eckenrode | LLVM has a Darwin libtool? Hmm. | 05:24:40 |

disclaimer for Gruber, but I have been happy to learn that the person who took responsibility for Liquid Glass and has otherwise overseen the decline in Apple UI design over the past decade has been replaced by an actual interface designer https://daringfireball.net/2025/12/bad_dye_job Amazing... I think I'll just stick to my plan of skipping macOS 26 entirely then. | 08:20:47 |
| Randy Eckenrode | I wonder if I can do something hacky to swift-toolchain-sqlite to make it devendor sqlite. 🤔 | 12:44:26 |
 vcunat | Ever seen something like this?

SyntaxError: invalid syntax
This wrapper stuff is auto-generated by buildPythonPackage and it does work on linux.
| 13:24:41 |
| vcunat | (except for a tiny non-python patch changing this hash, it's all just nixpkgs master) | 13:27:22 |
| vcunat | Oh, does macOS behave different than Linux around executing scripts? 🤔 | 13:28:36 |
| vcunat | i.e. maybe it's syntax error because a wrong interpreter is used? | 13:29:33 |
 K900 | That's a Python syntax error | 13:29:55 |
| K900 | In a script with clearly bash syntax | 13:30:00 |
| K900 | So something is trying to call python <bash script> | 13:30:12 |
| vcunat | Hmm, thanks. I think this moves me in a hopeful direction. | 13:32:28 |
| vcunat | I see. It's an unexpected interaction of nix-specific wrapping machinery with OS-specific piece of code from upstream. | 13:47:44 |
| vcunat | (when the script attempts to reexecute itself) | 13:48:07 |
 emily | shebangs don't work with shell wrappers on macOS | 15:57:16 |
| emily | i.e. if #!/nix/store/foo, then foo must be a makeBinaryWrapper rather than a shell wrapper | 15:57:28 |
| emily | perhaps something around that | 15:57:34 |

| Randy Eckenrode | I managed a stack overflow without triggering an infinite recursion. 🤔 | 19:01:50 |
 toonn | That's what we call sharpshooting : D | 19:10:11 |
| Randy Eckenrode | I think the problem is how I was trying to set up the Swift bootstrap. Because I already have a scope, I do overrideScope in the scope definition to declare a bootstrap version of the scope. I defined swift-bootstrap in the real scope as bootstrapSwiftPackages.swift, which uses swift-bootstrap to compile swiftc. | 19:12:13 |
| Randy Eckenrode | Fortunately, I found a way around it. Once I have SwiftPM not causing an infinite recursion, I’ll share the scope. | 19:19:56 |
| Randy Eckenrode | Also, llvm-install-name-tool supports -delete_all_rpaths, which the cctools one does not. That’s pretty handy. | 19:20:30 |
| Randy Eckenrode | (I tried making LLVM bintools the default for building Swift, but there is some work that needs to be done to make LLD actually work as a default linker on Darwin. The wrapper is not set up for it.) | 19:21:06 |
