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!
