-Dnosse option and Krylov

One of My system does not support SSE


CC = $(MPICH)/bin/mpicc -fopenmp -O3 -Dnosse -I$(FFTW)/include -I$(MPICH)/include

# make

DFT.o: In function `DFT’:
DFT.c:(.text+0x1d24): undefined reference to `Krylov’
DFT.c:(.text+0x1f70): undefined reference to `Krylov’
collect2: ld returned 1 exit status
makefile:219: recipe for target 'openmx' failed
make: *** [openmx] Error 1


if use "-Dnosse" option, Krylov.c is not compiled, then there was no Krylov.o

I want to know
1. How to (or is it possible) compile Krylov, with "-Dnosse" option?
2. Is it possible to compile DFT without Krylov.o

Could you show us the error message when the compilation of Krylov.c failed?
Is there mimic_sse.h in the source directory?
