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

[Christian Schulte]

Hi Vijay,

Not being an Apple user, let me still try a guess: you need to add
additional libraries:
 -lgecodeminimodel -lgecodedriver -lgecodegist

Please use the order as described in MPG.

Good luck
Christian

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

Continuing with http://www.gecode.org/pipermail/users/2014-April/004368.html

I am unable to get the basic example running from the tutorial.

On a MacBook, OS X 10.9.2, XCode 5.1.1, trying to install GECode 4.3 from
the webpage http://www.gecode.org/download.html

Downloaded source package, did a ./configure, make, make-install -- all
seemed to succeed.

The following command succeeds:

$g++ -O3 -I/usr/local/include -stdlib=libstdc++ -c money.cpp

However, the next command fails -- what am I doing wrong?

$g++ -v -o money money.o  -L/usr/local/lib -stdlib=libstdc++ -lgecodesearch
