To: mcxtrace-users at mcxtrace.org

Dear all, a bug in the 3.2 release of McXtrace has been found by one of our DTU users.


Instruments containing "anisotropic" SasView components will not compile out of the box, instead giving the compilation error

core_shell_cylinder:2944:43: error: expected ')'
  double l0, l1, k, l_full, l, dl, d_Phi, theta;
                                          ^

which indicates a doubly-defined 'theta' symbol in the generated component-codes.

If you need / want to use one of these anisotropic models, please either

  *   Pick a "fresh" comp from our Git repo (https://github.com/McStasMcXtrace/McCode/tree/main/mcxtrace-comps/sasmodels)
  *   Edit the first line in TRACE containing

TRACE
%{
  double l0, l1, k, l_full, l, dl, d_Phi, theta;

to instead read

TRACE
%{
  double l0, l1, k, l_full, l, dl, d_Phi;

A fresh McXtrace release will be spun out in the spring of 2024.


Best,
