Hi
If you want to use MKL10(no 8 or 9), you should obey instructions of R-admin.
MKL10 needs openmp. This needs gcc4.2 or later.
OpenMP for Intel was necessary with MKL10.0.1.x (There was not it in a
manual of MKL).
# Please try an additional effect of "-liomp5" in the %*%
# fp-model of Linux of IA32 is 387(80bit) about the precision,
# but SSE2(64bit) is a default in Intel64.
# It is caused by this that results are different.
There was not the problem in R-2.8.0 either
MKL_LIB_PATH=/opt/intel/mkl/10.0.5.025/lib/em64t
MKL=" -L${MKL_LIB_PATH} \
-Wl,--start-group \
${MKL_LIB_PATH}/libmkl_gf_lp64.a \
${MKL_LIB_PATH}/libmkl_gnu_thread.a \
${MKL_LIB_PATH}/libmkl_core.a \
-Wl,--end-group \
-liomp5 -lguide -lpthread -lgomp"
./configure --with-lapack="$MKL" --with-blas="$MKL"
