Hi everyone,
It’s my first time to making a geant4 project, I had a geant4 v11.2.o and did workes done, But the MacOS was updated to Sequoia and makes error on geant4. I updated the system and apparently works done, now Cmake calls a different sdk that I’ve installed. I think this may be a beginner’s mistake.

  • That’s the error:
    admin@MacBook-Pro-de-Leonardo build % cmake …

How can I fix it? I appraised than you can help me

Hi Leo

Looks like the problem is CMakeCache.txt in the build directory. It “remembers” previous builds. Simply remove it - a new one will be created.

Please try and let us know if it fixes things for you.

Hi John

I removed it and the problem is still there

OK. Let’s have another try.

How did you install Qt? With homebrew? If so, it installs both Qt5 and Qt6, and cross-links them is some way. It looks like you are building with Qt5 (I.e., you have not specified Qt6 explicitly - GEANT4_USE_QT_QT6=ON). To get Qt5, you have to unlink:

brew unlink qt

So, either specify Qt6 or unlink. (To get back to Qt6, brew link qt).

Goes without saying, at this level of problem, at every change, you should re-build from scratch in a clean build directory - or at least, remove CMakeCache.txt.

Let us know how you get on?

You need to remove the Geant4PackageCache.cmake file as this is the fundamental cause of the problem. This isn’t installed by default from version 11.3, so I suspect your v11.2 install is still around. Nevertheless, remove that file and the main error should resolve.

You may will then need to set CMAKE_PREFIX_PATH to include /usr/local/opt/qt@5 when building your application.
