[gecode-users] Compilation problem on MacOs with Gecode 4.3

Hi Guido --

I had the -stdlib=libstdc++ line in there only because you had suggested 
that it be so in 
http://www.gecode.org/pipermail/users/2014-April/004368.html :-)

So I went back and redid everything without Qt, to see what I would get.

This time I was able to get the following to work. So perhaps I had just 
gotten myself confused earlier... Any case, glad to have it working now! 
(Note: unlike what the manual said, I did need to include the 
-I/usr/local/include arg.)

  g++ -I/usr/local/include -O3  -c -o money.o  money.cpp
bash-3.2$ g++ -o money money.o -L/usr/local/lib    -O3 -lgecodeflatzinc 
-lgecodedriver  -lgecodesearch -lgecodeminimodel -lgecodeset 
-lgecodefloat -lgecodeint -lgecodekernel -lgecodesupport
bash-3.2$ ./money
SEND+MORE=MONEY
     {9, 5, 6, 7, 1, 0, 8, 2}

Initial
     propagators: 2
     branchers:   1

Summary
     runtime:      0.000 (0.252 ms)
     solutions:    1
     propagations: 14
     nodes:        7
     failures:     3
     restarts:     0
     no-goods:     0
     peak depth:   1

bash-3.2$
