Re: [Octave-bug-tracker] [bug #59475] Exceptions Running Octave with 64-bit Indexes

[David Laxer]

I did read the doc you alluded to and followed the instructions.
I download, built and installed OpenBlas, LAPACK, etc. and built them for 64 
bit.

E.g. 

make BINARY=64

Clearly, I did something wrong!
