[gecode-users] An error in the linking of an example

[Claudio Cesar de Sá]

Guido:

Really, the link for the gecodedriver library was missing. This detail was
not in the
example in the manual. Everything  works fine.

 My  script is done by:
#!/bin/bash

echo ""

g++ -I/usr/local/include -c money.cpp
echo "compilou ok"
g++ -o money_exe -L/usr/local/lib money.o \
  -lgecodeint -lgecodesearch -lgecodekernel -lgecodesupport -lgecodedriver
echo "linkeditou ok"
./money_exe
echo " FIM "

The execution is:

....../gecode-3.2.2/examples# sh sh_comp_money

compilou ok
linkeditou ok
SEND+MORE=MONEY
    {9, 5, 6, 7, 1, 0, 8, 2}

Initial
    propagators: 2
    branchers:   1

Summary
    runtime:      0.000 (0.197000 ms)
    solutions:    1
    propagations: 14
    nodes:        7
    failures:     3
    peak depth:   3
    peak memory:  10 KB
 FIM


Thanks for all for help me
