Tomorrow, we plan to initiate the update the build machine responsible to build:
- Slicer macOS application installer distributed on [https://download.slicer.org](https://download.slicer.org)
- corresponding Slicer extensions
## Implications for users
- Preview Slicer package and extensions may not be available for one or two days
## Implications for developers
This should allow us to update the minimum deployment target to 10.13 and build against the latest version of Qt5. See [COMP: Update minimum required CMAKE\_OSX\_DEPLOYMENT\_TARGET to 10.13 by jamesobutler · Pull Request #4940 · Slicer/Slicer · GitHub](https://github.com/Slicer/Slicer/pull/4940)

The upgrade has been completed of both the firmware and the operating system have been completed 🎉 (see below)
Next steps:
- Update XCode
- Update Qt5 installation
- Integrate [COMP: Update minimum required CMAKE\_OSX\_DEPLOYMENT\_TARGET to 10.13 by jamesobutler · Pull Request #4940 · Slicer/Slicer · GitHub](https://github.com/Slicer/Slicer/pull/4940) and [factory-south-macos: Update nightly builds to use Qt 5.15.0 by jamesobutler · Pull Request #27 · Slicer/DashboardScripts · GitHub](https://github.com/Slicer/DashboardScripts/pull/27)

I re-initiated the XCode update on the `factory-south-macos` build machine.
Once this is done I will start the Qt build using [5.15.0](https://github.com/jcfr/qt-easy-build/tree/5.15.0) branch doing the following:
```auto
$ ./Build-qt.sh -s macosx10.14 -d 10.13 -j 4
[...]
This script will build Qt for Darwin system
QT_VERSION : 5.15.0
OPENSSL_VERSION : 1.1.1d
[...]
Script options (macOS):
-a OSX architectures ............................ x86_64
-d OSX deployment target ........................ 10.13
-s OSX sysroot .................................. macosx10.14
```

It looks like the XCode update is incompatible 😕

Now downloading XCode 10.1 from [https://developer.apple.com/download/more/](https://developer.apple.com/download/more/)
That seems to be the latest version supporting 10.13.6 (see [here](https://developer.apple.com/documentation/xcode_release_notes/xcode_10_1_release_notes))
Indeed, version 10.2 and beyond requires macOS 10.14.3 or later (see [here](https://developer.apple.com/documentation/xcode_release_notes/xcode_10_2_release_notes))
For the record, the version currently installed is:
```auto
/usr/bin/xcodebuild -version
Xcode 8.2.1
Build version 8C1002
```

After downloading the file `Xcode_10.1.xip` it will be available in `~/Downloads`, then here are the steps:
- double-click on it from finder, it extracts to `Xcode.app`
- `sudo mv /Application/Xcode.app /Applications/Xcode-8.2.1.app`
- `sudo mv ~/Downloads/Xcode.app /Applications/`
Nest step is to download and install the command line tool:
Once the file is downloaded, double-click on the `.dmg` file, and then double click again on the `.pkg` file and following instructions.
After starting Xcode, you will be prompted with additional installation instructions.
XCode 10.1 is now installed:
```auto
$ /usr/bin/xcodebuild -version
Xcode 10.1
Build version 10B61
$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Qt5 build is moving along. I edited the instruction posted [above](https://discourse.slicer.org/t/2020-06-09-macos-packages-will-not-be-available-until-build-machine-is-updated-to-macos-10-13-6/11935/5). `macosx10.14` had to be specified as the SDK root (instead of `macosx10.13`)

The corresponding dashboard script have also been updated.
**Note:** Build of Slicer ‘Stable’ release extensions has been disabled on macOS
Assuming the Qt5 build completes, we should expect tonight Slicer preview build to complete without issues.

It turns out that Qt has been built in the wrong directory which caused the regular build to fail.
Qt is now being rebuilt following these instructions:
```auto
cd /Volumes/Dashboards/Support
./qt-easy-build/Build-qt.sh -s macosx10.14 -d 10.13 -j 4
```
This will ensure the Qt will be available in the expected directory `/Volumes/Dashboards/Support/qt-everywhere-build-5.15.0`

I haven’t tried myself, but as of 5.14.0 Qt is relocatable. See [https://www.qt.io/blog/qt-is-relocatable](https://www.qt.io/blog/qt-is-relocatable)

Good to know. It turns out I deleted the previous directory and restarted the build.

Updates:
- Qt 5.15 has been built on the factory
- Slicer build failed with `malformed mach-o: load commands size` error.
- A first attempt to address the problem was implemented in [Slicer/DashboardScripts@26a343](https://github.com/Slicer/DashboardScripts/commit/26a343d5670b97aac7b7d004f95041c6f6692231) by changing the basename from `Slicer` to `S`.
- With that change to number of failed tests went from `77` to `44`
Next steps:
- Update to use `P` instead of `Preview` and `S` instead of `Stable` to address remaining failures.

Updates:
- Reducing the path addressed some more issues there are remaining `malformed mach-o: load commands size` errors
Next steps:
- Evaluate these options:
- (1) Further reduce the path length by renaming the volume from `/Volumes/Dashboards` to `/Volumes/D`
- (2) Look into adapting the `ld` wrapper developed to address similar issue in NixOS:
- [https://github.com/NixOS/nixpkgs/pull/27536](https://github.com/NixOS/nixpkgs/pull/27536) and [https://github.com/NixOS/nixpkgs/issues/22810](https://github.com/NixOS/nixpkgs/issues/22810)
- [https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/bintools-wrapper/macos-sierra-reexport-hack.bash](https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/bintools-wrapper/macos-sierra-reexport-hack.bash)
I will probably go with option (1), this means we will have to rebuild Qt5, update cronjobs, …
We should look into (2) if we still have these issues after transitioning to the latest VTK, in this case we will have less libraries (no more `*PythonD.dylib`)

Updates:
- Volume has been renamed from `Dashboards` to `D`
- Cronjobs updated
- Misc python virtual env recreated
- Dashboard scripts updated (see [Slicer/DashboardScripts@2e56a8b](https://github.com/Slicer/DashboardScripts/commit/2e56a8b97b681b0e8d3a596b92f9de7cfb3194ae))
- Qt5 build in progress
🤞 If the timing is right, and we forgot nothing … tomorrow build should look better !
