Re: Building octave with large matrices support

[John W. Eaton]

As a start for checking consistency of integer sizes at compile time,
I checked in the following change:

  http://hg.savannah.gnu.org/hgweb/octave/rev/f26229391ea1

If configuring with the --enable-64 option fails to detect the proper
size integer and we are using gfortran, then -fdefault-integer-8 is
added to FFLAGS if it is not already there.  Checks for other
compilers could be added, but I don't know what the compiler names or
options should be.
