Has anyone built Slicer and Qt 5.15.2 on macOS Monterey with Xcode 13.2. I seem to be running into a lot of issues with building Qt5.15.2 from source (including JCFR’s easy script). I also tried to build Slicer with the Qt binaries but after building the code, I get a lot of errors related to link libraries. One example of the error is shown below:

Error(s):  
Cannot load library /S4-new2/S-s/Slicer-build/lib/Slicer-4.13/qt-loadable-modules/libqSlicerDataModule.dylib: (dlopen(/S4-new2/S-s/Slicer-build/lib/Slicer-4.13/qt-loadable-modules/libqSlicerDataModule.dylib, 0x0085): Symbol not found: \_\_ZN6vtksys18SystemToolsManagerC1Ev  
Referenced from: /S4-new2/S-s/Slicer-build/lib/Slicer-4.13/qt-loadable-modules/libqSlicerDataModule.dylib  
Expected in: /S4-new2/S-s/Slicer-build/lib/Slicer-4.13/qt-loadable-modules/libvtkSlicerDataModuleLogic.dylib)

Any idea how this could be resolved?

I’ve built on Monterey (12.1) with Qt 5.15.2 and Xcode 13.2.1, though not for a couple of weeks. Not sure what those link errors are, sorry, but that configuration should work.

I typically use Qt from homebrew on mac with no problem, but I haven’t built from scratch in a while.

Same for me (Qt from homebrew).

Thanks Steve and Hollister. I am trying to create a Slicer package for a collaborator with a custom module, therefore trying to build Qt from source.

I just configured with this `cmake` line:

```
cmake -DCMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.15 -DCMAKE_BUILD_TYPE:STRING=Debug -DQt5_DIR:PATH=/usr/local/Cellar/qt/5.15.2/lib/cmake/Qt5 ../Slicer

```

and it’s building now. Should work, I’ll let you know if it doesn’t.

Even if you’re making a custom module, why do you need to build Qt from source?

So this is kinda odd. I now get:

Looks like \_\_ASSERT\_FUNCTION is from assert.h? Am I misreading this?

Hey @pieper Steve, have you seen this ITK problem on a Mac? (or anybody else)?

I am experiencing the same issues when starting Slicer.

cmake configuration below:

```auto

   cmake ../../sources/cpp/Slicer/ \
    -DCMAKE_OSX_DEPLOYMENT_TARGET:STRING=12.1 \
    -DQt5_DIR:PATH=/Users/herzc/Qt/5.15.2/clang_64/lib/cmake/Qt5 \

Getting errors like this:

I am using Qt from the online installer but can also try again with the one installed from brew (but Qt designer doesn’t work with that one)

I will try again with the cmake configuration from here: [Slicer build on macOS Monterey - #6 by hherhold](https://discourse.slicer.org/t/slicer-build-on-macos-monterey/21940/6)

Something relatively recent changed; I can build a fork from late January but the latest master fails.

The build machine looks okay though, I wonder if it’s a Monterey thing with some recent update?

Building an early Jan version works, but I am still getting the same errors when starting Slicer.

I will try with your configuration.

I looked through the 85 or so commits between the branch I have from late January (I said fork before, sorry, meant branch) and master from today, but nothing was obvious. I might try a binary search and see what broke things, I’ll let you know if I get to this.

Thanks - let us know what you find. I haven’t had a chance to try building since my mac (and my brain) are tied up with some other projects.

Also, why the nightly builds aren’t broken, I have no idea. My guess is that machine isn’t running Monterey? I’m running 12.1 right now.

Hi Steve @pieper ,

I saw the change to ITK in the most recent commit but I still get this error, the failing target is vtkITKPython. Any ideas?

Thanks!

I tried compiling again and getting the same errors:

```

So far only reverting changes to early 2022 worked for me.

@hherhold @che85

I’ve experienced the same issue on Monterey. I dug a little deeper, and it looks like the root cause is the preprocessor identifier \_POSIX\_SOURCE being defined during compile of vtkITK.This causes itkMacro.h file to conditionally include code which depends on Linux specific details of assert.h.

I sent a [PR](https://github.com/Slicer/ITK/pull/6) which uses the more granular \_\_linux preprocessor identifier for this conditional to Slicer/ITK and once approved will duplicate this to the main ITK repository.

Good catch! This appears to work on my machine as well - vtkITKPython target was the one failing, and it just finished. Rest of the build proceeding.

Nicely done!
