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