[gecode-users] Newbie problem

[Guido Tack]

Hi Torsten,

you seem to have an older version of Gecode installed in /usr/local (that's what the clang error messages point to).

The 35 is the "library version", which is simply incremented with each release and doesn't follow the major.minor.patch scheme.

Cheers,
Guido

I was surprised to find that /Library/Frameworks/gecode.framework/Versions/ contains a folder named "35" -- I would have expected it to be named "42", for version 4.2, but that could of course be simply a wrong guess on my part.
