After a few days of reading and headache, I finally gave a try at
building R from source with Intel MKL and ICC. Documentation and posts
on this topic are rather incomplete, sometime fantasist et do not give
much explanations about configure options.
As I am not sure if mine is correct, I would appreciate some advices and hints.

OS: Fedora 22
parallel_studio_xe_2016
Hardware : 8 Thread(s) per core: 2 Vendor ID: GenuineIntel Model name:
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz - Sandybridge
R-3.2.2

Here is my build configuration:

-------------------------------------------------------
source /opt/intel/compilers_and_libraries_2016/linux/mkl/bin/mklvars.sh intel64
source /opt/intel/bin/compilervars.sh intel64
_mkllibpath=$MKLROOT/lib/intel64
_icclibpath=$MKLROOT/linux/compiler/lib
export LD_LIBRARY_PATH=${_mkllibpath}:${_icclibpath}
export MKL="-L${_mkllibpath} -L${_icclibpath} -lmkl_intel_lp64
-lmkl_intel_thread -lmkl_core  -liomp5 -lpthread"
export CC="icc"
export F77="ifort"
export CXX="icpc"
export AR="xiar"
export LD="xild"
export CFLAGS="-O3 -ipo -openmp -parallel -xAVX"
export CXXFLAGS="-O3 -ipo -openmp -parallel -xAVX"
export FFLAGS="-O3 -ipo -openmp -parallel -xAVX"
export MAIN_LDFLAGS='-openmp'
./configure --with-lapack --with-blas="$MKL" --enable-R-shlib
--enable-memory-profiling --enable-openmp --enable-BLAS-shlib
--enable-lto F77=${F77} FC=${F77}
------------------------------------------------------------

After I run ./configure, it seems from config.log everything is fine:

checking for dgemm_ in
result: yes

checking whether double complex BLAS can be used
result: yes

checking whether the BLAS is complete
result: yes

The only error I can see is ld complaining about not finding -lRblas
----------------------------------------------------------------------------

Then run $ make with no errors.
Now, with no $ make install, I get this:

Now a few questions:

EDIT

1- am I not supposed to see these libraries in the list ?
libmkl_intel_lp64.so
libmkl_intel_thread.so
libmkl_core.so

You are looking in the wrong place. With the option --enable-BLAS-shlib,
R is linked to MKL via the library libRblas.so which you will find in
the directory "lib" after building R.

Right.
$ ls lib
libRblas.so*  libRlapack.so*  libR.so*

$ ldd bin/exec/R returns
....
libRblas.so => not found

Shall I let things like that or tell R the path to libRblas.so ?
