Thanks, Markus.

The easiest fix would probably be to provide a primitive format string:

warning ("%s", (string("Mshichmanhodgesmosfet: unknown parameter").append (parameternames[niter])).c_str ());

On an unrelated note: You might run into issues with the lifetime of the temporary string. I.e. the c_str pointer might be dereferenced by "warning" after the temporary string was already deleted. It's probably safer to assign it to a variable with well-defined scope:

string warn_string = string ("Mshichmanhodgesmosfet: unknown parameter").append (parameternames[niter]);
warning ("%s", warn_string.c_str ());

Compilation of package ocs fails when -Werror=format-security (the default when building Debian packages, to avoid uncontrolled format string vulnerability):

mkoctfile Mshichmanhodgesmosfet.cc
Mshichmanhodgesmosfet.cc: In function ‘void set_parameters(ColumnVector, string_vector, double*, double*, double*, double*, double*, double*, double*, double*, double*, double*, double*, double*)’:
Mshichmanhodgesmosfet.cc:108:103: error: format not a string literal and no format arguments [-Werror=format-security]
  108 |  warning ((string("Mshichmanhodgesmosfet: unknown parameter").append (parameternames[niter])).c_str ());

Is there a simple way to fix this issue?
