hi Samuel,
this is a common problem on this machine. it happens because the Cactus build process at some point relies on an environment variable called "MPI", and this machine also defines a variable called "MPI" as an env variable. so these two definitions clash.
to go around this issue, you need to unset this variable before compiling. ie, you just have to do:
$ unset MPI
and then follow with the compilation as you normally would.
cheers, Miguel

Hi,
while trying to build the ET on the Marenostrum cluster (from the Barcelona Supercomputing Center) I obtain the following error:
Configuring with flesh MPI Warning: use of flesh MPI via MPI option is deprecated and should be replaced with the thorn ExternalLibraries/MPI and its MPI_DIR option MPI selected, but no known MPI method - what is "impi" ? Error reconfiguring sim_cx-config make: *** [Makefile:732: sim_cx- config] Error 2
The MPI thorn is on the thornlist and can be found on the repos folder as an external library. On the other hand, members of my group have already installed the Toolkit on this cluster, and I am using the same configuration file as they are, so I am unsure what the problem might be.
I am still quite new to this kind of task, so I would appreciate any help. Thanks!
