[Octave-bug-tracker] [bug #52425] eigs function regresses

[Kai Torben Ohlhus]

Follow-up Comment #29, bug #52425 (project octave):

@Rik: The patch (file #42524) lets me go on as before.  Thank you for that and
please push that one as well!  Most of the FORTRAN checks don't need that
save&restore as they do not really compile any FORTRAN source code.

Just for the files: my prior workaround (comment #26) did not work.  Using
"-fdefault-integer-8" within the FFLAGS causes  liboctave/external/ranlib (all
FORTRAN) to be compiled with INTEGER == uint64_t and messes up all RNGs that
rely on 32 bit integers... It really raises some doubts about the reliability
of Octave's FORTRAN heritage, but that is for another bug report.


./configure [...] F77_INTEGER_8_FLAG='-fdefault-integer-8' [...] --enable-64
[...] --with-arpack='-larpack_Octave64'

[snip]

checking for dseupd in -larpack_Octave64... yes
checking whether the arpack library works... yes
checking whether the arpack library is free of bugs... yes

[snip]

  64-bit array dims and indexing:       yes
  64-bit BLAS array dims and indexing:  yes

[snip]

Summary:

  PASS                            15943
  FAIL                                0
  XFAIL (expected failure)            5
  XFAIL (reported bug)               32
  SKIPPED (feature)                  37


Yesterday there were unnoticed errors.
