Hi,

We were compiling a program with MKL.

The error shown is:
[ded@wci32-oib mm-app-0.0.2]$ make

mm.c -o mm

The Makefile is as follows:

MKL_DIR = /home/ded/intel/mkl/9.1.023
MKL_PATH = $(MKL_DIR)/lib/32
MKL_INCLUDE = $(MKL_DIR)/include

all: mm

mm: mm.c
cc -I$(MKL_INCLUDE) -I$(MPI_INCLUDE) -L$(MKL_PATH) -lmkl_p4 -lguide -lpthread -lm
mm.c -o mm

clean:
rm -f mm

It looks as if your mpicc may be a 64-bit compiler, so you would have to switch to the corresponding library in the em64t section of your MKL library installation.
If your only reason for linking in Intel OpenMP support is on account of MKL, and you don't intend to ask for threading in MKL, the mkl serial library may be preferable.
