Anže, I managed to compile therion from source yesterday, on an Apple Silicon Mac, but with the previous version of macOS Sequoia 15.6.1. I used the v6.3.4 tag (17059ab27ce491f1edac150da2b7e2011f79b800). Are you using the CMake build method? I did install the dependencies via Homebrew (taken from the `ladislavb/homebrew-therion` repository): brew install BWidget cmake catch2 fmt freetype ghostscript imagemagick lcdf libjpeg libpng pkg proj tcl vtk wxwidgets zlib brew install --cask xquartz Olly

Greetings.
I've been trying to reinstall Therion on a new M-series macbook on the newest OS (Tahoe) but have run into several 'dead ends'.
(1) First I tried the homebrew method, but I ran into the same issue as several others. The whole homebrew route seems to be broken currently.

(2) I tried to compile it from source, but it gets stuck while trying to compile Loch with the following error:
In file included from lxSetup.cxx:39: ./lxData.h:35:10: fatal error: 'vtkPolyData.h' file not found 35 | #include <vtkPolyData.h> | ^~~~~~~~~~~~~~~ 1 error generated. make[1]: *** [lxSetup.o] Error 1 make: *** [loch/loch] Error 2
Does anyone know of a solution, how to tackle any of these problems by chance? Thanks in advance, Anze
