</span>From your log I see that Cactus says: Found MPI compiler wrapper at<br>
/opt/local/bin/mpiCC. This is likely the problem. Apple still doesn't<br>
use a case sensitive filesystem by default, which means this is the same<br>
as mpicc, which is the C compiler. The compiler itself is smart enough<br>
(in the case of gnu) to figure this out at compile time, so you don't<br>
get an error there. At link time however, (and because Cactus uses the<br>
C++ compiler for linking), this can result in C++ libraries not being<br>
linked, and thus C++ symbols are missing (as seems to be the case in<br>
your log).<br>
<br>
Now, the thorn MPI should have picked up /opt/local/bin/mpic++ before<br>
mpiCC, if the former exists. Does it? If not - is there some package you<br>
still need to install (like openmpi-c++ or such)?<br>
