I've run into this recently so it's still fresh what to do. Basically you have to compile openblas yourself.

It's not too hard but, of course, a PITA. Download it from http://www.openblas.net then edit the file Makefile.rule and search for "64". You need to change a couple of things - BINARY64=64 INTERFACE64=1. Then make and make install.

Something Julia does is provide binaries with all the dependencies included, precompiled for generic 64 bit Linux. I think this is a neat idea - the whole bundle is 178M unpacked. The amount of pain saved is worth duplicating the libraries... I know, heresy to say that on Linux! ;)

Hello community,

since I need to enable large arrays, when trying to build octave-4.0.0 from source (tar.gz from ftp) with --enable-64, I got the following error :

./configure --enable-64
[...]
checking for sgemm_ in -lblas... (cached) yes
checking for sgemm_ in -lessl... (cached) no
checking for sgemm_ in -lblas... (cached) yes
checking whether LSAME is called correctly from Fortran... yes
checking whether ISAMAX is called correctly from Fortran... yes
checking whether SDOT is called correctly from Fortran... no
checking whether DDOT is called correctly from Fortran... yes
checking whether CDOTU is called correctly from Fortran... no
checking whether ZDOTU is called correctly from Fortran... no
checking whether the integer size is correct... no
configure: error: BLAS doesn't seem to support 64-bit integers.  This is incompatible with --enable-64.

Same from sources 3.8.2 makes no error.

Actual archtecture (uname -a) :
Linux titipc 3.19.0-33-generic #38-Ubuntu SMP Fri Nov 6 18:18:12 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Thank's.
Fred
