[mcstas-users] Version 2.4.1 on High Sierra (10.13.3)

[Peter Willendrup]

Hi both,


Andrew is right, this could easily be the issue.

(These days, to come around rare numerical issues with the Apple-provided “gcc”/clang, I have enclosed what is supposed to be a “full” gcc inside the McStas application bundle. For this reason the recommended way to run a command-line environment is via mcstas-2.4.1-environment.)

If the problem persists / is something else Christoph, you may also experiment by changing which compiler is used - easiest via File -> Preferences in mcgui.  Setting it to /usr/bin/gcc will run the system-default gcc.


Best,

Peter
