[gecode-users] failed to link with branch

[Gustavo Gutierrez]

Hi Ronen,

I think the problem can be related to the linker and the standard library
used to build gecode on the mac. The std::__1:: usually means that you are
using symbols from libc++. What I would do is to make sure you are using
clang (and not gcc) to build gecode. In general make sure that you are
using the same compiler you build gecode with.

If you used clang (the default c++ compiler for some versions of MacOS) be
sure to pass -stdlib=libc++

Cheers,
Gustavo
