Re: I need help for compile of 64 Octave on Ubuntu

[siko1056]

Like Andy says, if you are really sure you need 64-bit indices, it requires
you to compile OpenBLAS, SuiteSparse, Arpack-NG, and QRUPDATE yourself.
Besides the link Doug provided, there is the MXE-Octave project [1] to build
all of Octave's dependencies (mostly intended for the Windows-Port).
Admittedly, I never got MXE to work on my Linux system. Maybe I did not try
hard enough and I found it too heavy to compile all the dependencies my
distributions provides anyway.

Some more lightweight approaches to only compile the minimum required
libraries for 64-bit indexing is to my knowledge a project of Mike [2] and a
similar one by me [3]. The most interesting parts of [2] and [3] for you are
the `configure` and `make` flags and parameters for an own approach. 

HTH, Kai

P.S.: Currently I am able to build a 64-bit Octave version on openSUSE 42.3
using [3].
