This lets math/libqalculate build with clang6.
The error is:
/usr/ports/pobj/libqalculate-0.9.7/libqalculate-0.9.7/libqalculate/MathStructure.cc:7166:48:
error: cannot initialize a parameter of type 'MathStructure *' with an rvalue
of type 'bool'
MathStructure::gcd(cont_c, cont_d, gamma, eo, false);
^~~~~
The function prototype of MathStructure::gcd in MathStructure.h is:
static bool gcd(const MathStructure &m1, const MathStructure &m2,
MathStructure &mresult, const EvaluationOptions &eo,
MathStructure *ca = NULL, MathStructure *cb = NULL,
bool check_args = true);
Their latest Github code and libqalculate-0.9.8 indicate that it is
meant to be:
MathStructure::gcd(cont_c, cont_d, gamma, eo, NULL, NULL, false);
