This sounds a bit mysterious. What is the output of
nm -D /home/hgcastro/precice/lib64/libprecice.so | grep precice15SolverInterface
This will you a longer cryptic output looking similar to this (but more output):

It would be interesting to see whether the missing symbol _ZN7precice15SolverInterfaceC1ERKSsS2_ii (as mentionde in the ldd.log) is indeed missing.
Currently, my best guess would be that the compilers are still somehow mixed up as in this older forum post.
