Hi,
I tried to compile the example "Send More Money" from the pdf
"Modeling and Programming with Gecode", page 14.
The compiler stops with following errors:
In constructor 'SendMoreMoney::SendMoreMoney()':
error: '(Gecode::IntVarBranch)10u' cannot be used as a function
error: '(Gecode::IntValBranch)0u' cannot be used as a function
The line causing the error is (you can find the complete code at the
end of this mail):
branch(*this, l, INT_VAR_SIZE_MIN(), INT_VAL_MIN()); // defined in
set.hh
As far as I know this kind of error occurs when you use a variable
with the same name as the function, but there is no
variable with this name. Searching with google didn't show any useful
results so I am asking here for help.
I'm using qtcreator on ubuntu 12.04.

Example from the book:
#include <gecode/int.hh>
#include <gecode/gist.hh>
using namespace Gecode;
class SendMoreMoney : public Space {
protected:
IntVarArray l;
public:
SendMoreMoney(void) : l(*this, 8, 0, 9) {
IntVar s(l[0]), e(l[1]), n(l[2]), d(l[3]),
m(l[4]), o(l[5]), r(l[6]), y(l[7]);
rel(*this, s, IRT_NQ, 0);
rel(*this, m, IRT_NQ, 0);
distinct(*this, l);
IntArgs c(4+4+5); IntVarArgs x(4+4+5);
c[0]=1000; c[1]=100; c[2]=10; c[3]=1;
x[0]=s; x[1]=e; x[2]=n; x[3]=d;
c[4]=1000; c[5]=100; c[6]=10; c[7]=1;
x[4]=m; x[5]=o; x[6]=r; x[7]=e;
c[8]=-10000; c[9]=-1000; c[10]=-100; c[11]=-10; c[12]=-1;
x[8]=m; x[9]=o; x[10]=n; x[11]=e; x[12]=y;
linear(*this, c, x, IRT_EQ, 0);
branch(*this, l, INT_VAR_SIZE_MIN(), INT_VAL_MIN());
}
SendMoreMoney(bool share, SendMoreMoney& s) : Space(share, s) {
l.update(*this, share, s.l);
}
virtual Space* copy(bool share) {
return new SendMoreMoney(share,*this);
}
void print(void) const {
std::cout << l << std::endl;
}
};
int main(int argc, char* argv[]) {
SendMoreMoney* m = new SendMoreMoney;
Gist::dfs(m);
delete m;
return 0;
}
