Intel Toolchain[edit]

I do not endorse using the Intel Compiler or Math Kernel Library, I always endorse using completely free software solutions. I am simply evaluating how compatible Octave is with the Intel development tools and putting some notes here.

Intel Compiler[edit]

To compile Octave with the Intel compiler (tested with version pass the following variables to configure:

Code: Intel compiler variables
CFLAGS="-g -O2 -diag-error 10006,10155,10156,10157,10158"
CXXFLAGS="-g -O2 -diag-error 10006,10155,10156,10157,10158 -diag-disable 654,1125"
FFLAGS="-g -O2 -diag-error 10006,10155,10156,10157,10158"

The -diag-error 10006,10155,10156,10157,10158 options tell the compiler to treat unknown command-line options as errors instead of warnings. This allows the configure script to correctly detect which options are recognized by the compiler.

The -diag-disable 654,1125 setting for C++ turns off warnings about shadowing member functions. I may turn these back on at some point to compile a list of these warnings, but ignore for now.

Intel Math Kernel Library[edit]

The IMKL provides a library interface that includes BLAS, LAPACK, and FFTW functions, so it should be possible to use it in place of all three of those libraries.
