Octave 3.8.1 with MKL

[Zoltan_K_]

I am trying to rebuild GNU Octave  with the Intel MKL on Ubuntu 14.04

uname -a

Linux zoli-Precision-WorkStation-T3500 3.13.0-27-generic #50-Ubuntu SMP Thu May 15 18:06:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

base on the description:

https://software.intel.com/en-us/articles/using-intel-mkl-in-gnu-octave

The only thing I haven't done is to edit the  configure.in file since there is no such file in the source directory of Octave 3.8.1. But this has something to do with fft which I don't need now anyway (I guess it's not a problem).

Having set the enviroment variables (CC, CXX, F77, CFLAGS, CPPFLAGS, LDFLAGS) I run configure with the suggested parameters and I get the following error:

checking whether ifort has the intrinsic function ISNAN... yes
checking whether ifort generates correct size integers... no
configure: error: your Fortran compiler must have an option to make integers the same size as octave_idx_type (int).  See the file INSTALL for more information.

I have installed both the Intel C++ and Fortran compilers (l_ccompxe_2013_sp1.3.174 and l_fcompxe_2013_sp1.3.174) with only the 64 bit option.

SInce the error message refers to Fortan I posted this problem here but not sure if it is really the problem of the Fortran compiler.

Could anyone help me please?

I've moved this over to the MKL forum as folks there may be more familiar with this. I will comment that Intel Fortran's default integers are the same as C int, so maybe you added an option to change it that isn't shown in the article.

Were you able to figure this out?  I was using ifort and icc as well.

I've got the same issue while configuring octave 4.2.0, using parallel_studio_xe_2017_update1 and l_mkl_2017.0.098.

./configure --with-blas="-Wl,--start-group -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -Wl,--end-group -liomp5 -lpthread" --with-lapack="-Wl,--start-group -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -Wl,--end-group -liomp5 -lpthread" --enable-fortran-calling-convention=gfortran

Did you find a solution?
