Looking at the output, it seems that Cactus uses mpicc, while icc reports and error. Does mpicc maybe use icc? What happens if you type "mpicc --version"?
Generally, I recommend against using mpicc, since it complicates the configuration stage (it may be difficult to run small test programs). With cross-compiling, this may not be so much of an issue since you can't run test programs anyway.
I assume that you are trying this with an empty thorn list?
Your option list looks strage. Is this really a Fedora system?
You are setting MPI_DIR = /opt/apps/intel13/impi/4.1.0.024/intel64. Does this make sense, if you expect to not be using icc? What compiler should be used to generate the code, gcc or icc?
You are setting FPP_OPENMP_FLAGS = -D_OPENMP; this is only necessary for very old versions of GNU cpp. For modern versions, I recommend FPP_OPENMP_FLAGS = -fopenmp.
You are using -rdynamic in CFLAGS. This is a linker option; it should go to LDFLAGS instead.

I'm trying to build on MIC. In order to do that, I have to cross compile. See attached cfg file.
Anyhow, I build with simfactory and get this:

So I expect the mpicc compiler to be used. It isn't. What am I doing wrong?
