Therion date data delimiter
by bruce＠tomo.co.nz 13 Nov '25

13 Nov '25

Good morning I've just inherited some Therion survey data that includes dates defined: date 1985 2 16 (as opposed to date 1985.2.16) A cursory look suggests it is working, in that no errors or warnings are reported, and Aven seems to be interpreting the dates of the surveys exported from Therion. The Therion Book suggests that . is the only valid delimiter in this position - no mention of using a space. Is there any problem with using a space as the date delimiter? Regards Bruce

macOS installation

05 Nov '25

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. https://github.com/ladislavb/homebrew-therion/issues/15 (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 *Anže Abram* Ulica bratov Učakar 84, 1000 Ljubljana SI - Slovenia *M* +386 41 480 906 *@* anze.abram(a)gmail.com *Naše oči je zalila* *lava goreča*.
